How To Replace A Water Heater

Learn How to Install a New Water Heater

Because professional installation may easily add $500 or more to the cost of replacing a traditional tank-style water heater, many homeowners are naturally interested in the option of doing it on their own. Furthermore, while it is considered an advanced project, DIYers with sufficient skill may frequently do the task themselves with a little forethought. It’s crucial to highlight that this is not a project for those who are just getting started. Examining the type of water heater you already have is the first step in learning how to install a new water heater in your home.

Then decide on the size: 30-, 40-, 50-, or larger-gallon containers.

You might consider upgrading to a larger unit if your old one did not provide enough hot water.

However, there must be enough space for the larger heater, the flue size must be correct with proper pitch, and the gas line supplied must be sufficient for the heater’s capacity.

Plumbers bid jobs on the basis of a full day’s worth of labor, however, because the project typically grows more intricate as time goes on.

If you’re not sure in your abilities in these areas, hiring a professional is the best course of action.

When it comes to dealing with gas lines, it’s important to always abide by municipal regulations.

Gas Water Heater Venting

Given that professional installation may easily add $500 or more to the cost of upgrading a traditional tank-style water heater, many homeowners are naturally interested in the prospect of doing it themselves. Furthermore, while it is considered an advanced project, DIYers with sufficient expertise can frequently complete the task themselves with a little forethought and preparation. Note that this is not a project for those who are just getting started with computer programming. Examining the sort of water heater you already have is the first step in learning how to install a new water heater on your own.

Then decide on the size: 30-, 40-, 50-, or larger-gallon drums.

However, if your old water heater did not provide enough hot water, you might want to consider upgrading to a larger unit—say, from a 40-gallon to a 50-gallon unit.

(Any modifications to gas lines should only be performed by a certified expert.) In the best-case scenario, replacing the heater requires only a few hours of labor, which includes disconnecting and removing the old heater, then bringing the new heater into position and reconnecting all of the connections in the same manner.

Making plumbing connections, as well as electrical or gas connections, and a vent connection if you have a gas water heater will be required while replacing the water heater.

A professional is the ideal course of action if you are not sure in your abilities to do so. The installation of gas connections may even be prohibited in some places for homeowners. Work involving gas lines should always be done in accordance with local laws and regulations.

Warning

All plumbing installations must be in compliance with the local plumbing code, so check with your local building authority to find out what is required in your region. Because installation varies depending on the location and the kind of heater, the following procedures are intended to serve as a general guideline only and may or may not apply to your specific case. As previously indicated, it is preferable to leave this process to the pros.

Materials

  • Purchase of a new water heater, as well as any necessary shimming, plumbing fittings, and plumber’s pipe-seal tape. a draft cowl for the water heater (if one is required for a gas heater)
  • Temperature and pressure relief valves (if not already given)
  • A drain valve for the water heater (if not already provided)
  • Fittings for vent pipes (where required)
  • Nipples for galvanized water heaters with a plastic liner (2)
  • Flexible water heater tubing (if required)
  • Flexible gas heater tubes (if required)

Shut off the Water, and the Gas or Electricity

  • Turn off the power to the existing water heater and disconnect the water heater’s plumbing. Turn off the water at the main water cutoff valve in the home or at a branch shutoff valve that controls the cold water that runs to the water heater in the basement. Then turn off the electricity or gas to the building. For an electric water heater, follow these steps: Turn off the circuit breaker for the water heater’s circuit in the breaker box for the house. a. This is normally a double-pole breaker with a 30-amp rating. For a gas water heater, turn off the gas supply at the shutoff valve on the gas line that is closest to the water heater and then turn on the water heater. Water main should be shut off at the water meter. Home-Cost.com

Drain the Water Heater Tank

  • A garden hose should be connected to the drain valve located towards the bottom of the water heater. Open the nearest hot water faucet, such as the one in the bathroom, to avoid suction from building up in the line, which can cause the draining to become sluggish. Place the other end of the hose over a floor drain or direct it to an open area outside. To prevent silt from clogging the drain valve, open it carefully when first turning it on. Allow the tank to empty entirely before turning off the valve and removing the hose from the tank. It is positioned at the bottom of the water heater, near the drain valve.

Disconnect the Water Lines

  • Disconnect the hot and cold water lines from the water heater by using a pipe wrench or channel-lock pliers to tighten the connections. Flexible tubes (usually coupled with compression or union fittings) or soldered connections (soldered connections must be cut with a tubing cutter) can be used to connect the water lines to the heater.

Disconnect the Electrical or Gas Lines

  • Next, the water heater’s power source must be unplugged from the mains power supply. For an electric water heater, follow these steps: Removing the cover from the wire connection panel at the top of the water heater will reveal the wire connections. Check the individual wires with a non-contact voltage tester to ensure that the circuit is off, and then remove the wire connectors that link the circuit wires to the water heater leads. Remove the cable from the connection box by unscrewing the cable clip and pulling the cable out. For a gas water heater, follow these steps: Remove the gas line from the water heater and make sure the main gas line valve is turned off before reconnecting it to the gas control valve. Depending on the kind of water heater, this gas tube may be a flexible tube covered with vinyl or bare soft copper tubing, or it may be an older water heater with a hard black-pipe connection.

Disconnect the Water Heater Vent (Gas Heaters Only)

  • The vent pipe should be disconnected from the draft hood located on the top of the heater. In most cases, three or four sheet metal screws are used to attach the draft hood to the exhaust vent pipe. In certain cases, if the draft hood is in excellent condition, it may be possible to repurpose it with the new water heater.

Swap the Old Water Heater for the New

Use an appliance dolly with straps to move the old water heater out of the way and wheel in the new water heater. The use of a helper is recommended while moving water heaters up and down basement steps. When transferring the heater, make sure you tie it to the dolly with strong straps. Clean up the area on the floor where the old heater used to be. Bring in the new water heater and align it with the existing plumbing connections so that it is connected to the water heater’s plumbing system. Shimming beneath the legs of the new water heater can help to level it if necessary.

Tip

  • If you live in an earthquake-prone area, there may be brackets or straps that need to be attached to the wall to keep the water heater from moving about while in use. The water heater should be installed. Getty Images

Install the Relief Valve and Other Fittings

  • Install all of the necessary fittings that are required for the water heater to function properly. This always comprises a temperature and pressure relief valve (also known as a TPR valve) as well as a drainpipe for discharge. Follow the manufacturer’s instructions to install any additional fittings that may be required. Relief valve for high temperature and high pressure

Connect the Water Lines

  • Tie galvanized plastic-lined nipples to the cold water input and hot water outlet ports on the top of the water heater using stainless steel screws. In order to install the nipples, you must first cover the threads with plumber’s pipe-seal tape before threading the nipples into the apertures and tightening them using channel-lock pliers or with a pipe wrench. Connect the cold water pipe to the intake nipple on the water heater, and the hot water pipe to the output nipple on the water heater to complete the installation. In some circumstances, reattaching the flexible tubing that were removed after removing the old heater might be as simple as plugging them back in. When the water pipes are hard-piped into the water heater and cutting is necessary to remove the water heater, the operation becomes a little more difficult. The water heater nipples will be connected to the cold and hot water pipelines through the use of different threaded adapters, short sections of pipe, and union fittings, which will need assembly. The method you use will be determined by the type of pipe you have and the layout of your plumbing system, among other factors. If you have copper pipes, you may need to sweat-solder them together with a torch, but there are compression fittings, grip-fit (SharkBite) fittings, and PEX fittings that can be used with a variety of plumbing pipes. The installation of flexible tubes to link the hot and cold water pipes to the water heater is a suitable time to do so if you do not already have them in place. The water heater will be more easily disconnected if you ever need to repair or replace it in the future. Male-threaded adapters must be attached to both the water heater nipples and the ends of the hot and cold water pipes in order to do this. The flexible tubes are then threaded into the adapters and secured using coupling nuts that screw into the adapters.

Connect the Gas or Electrical Lines

  • Connect the gas or electricity sources, depending on their location: For a gas water heater, follow these steps: Connect the gas line to the control valve for the gas burner. Use a flexible gas line if it is available and permitted by local regulations. Check for leaks by turning on the gas supply valve and scrubbing the gas union and any gas joints with a soapy water solution until they are clean. If you notice any bubbles, this indicates that the connection is leaking and that it needs to be tightened. If you are still unable to achieve a satisfactory seal without bubbles, contact your gas provider or a plumber for assistance. For an electric water heater, follow these steps: Connect the electrical cable to the water heater’s wire connection box, which is located at the top of the water heater. Wire connectors should be used to connect the circuit wires to the water heater lead connections. The cover plate for the wire connection box should be attached.

Reconnect the Vent (Gas Heaters Only)

The draft hood should be installed at the top of the water heater, centered above the exhaust aperture, and then inserted into the exhaust pipe. Sheet-metal screws are used to hold it in place. You may need to reduce the vent pipe if the new water heater is higher than the old one. You may accomplish this by cutting the vent pipe down to size using metal shears or by installing a shorter pipe segment. Another option is to lengthen the vent by installing an additional vent pipe segment if your water heater is less than the standard length.

The new water heater should come with its own set of parts and operating instructions.

Tip

  • Shared venting with a chimney or flue that simultaneously serves a furnace (as seen above) is no longer permitted in some municipalities. This means that you may need to hire a professional to reroute the venting for your new water heater in this situation. Getty Images

Complete the Installation

  1. Connect the hot water faucet to a distant position in the home, then turn on the cold water supply valve to the water heater, allowing the water heater tank to fill with water until the hot water tap is turned off. When water begins to flow from the hot water faucet, you’ll know the tank is completely full. Turning the circuit breaker back on for an electric water heater will re-energize the circuit that supplies electricity to the water heater. If you’re using a gas heater, make sure the main gas valve is open and that the pilot igniter is functioning correctly by following the manufacturer’s instructions. Make your chosen temperature selection on the water heater’s thermostat (120 degrees Fahrenheit is suggested), then wait for the water in the tank to get up to temperature before using it. Turn on the heater and adjust the temperature of the water heater. Banks Photographs courtesy of Getty Images

Introduction

When your water heater begins to leak, you must act quickly to have it repaired or replaced. We’ll teach you how to set up your own natural gas water heater in less than a day’s time. Even if you do not require a new water heater at this time, it is likely that you will require one within the next few years. Water heaters typically have a lifespan of seven to fifteen years. If yours is beginning to show signs of wear, this post is also for you. If you’re familiar with basic equipment and have a little expertise soldering copper, replacing a water heater shouldn’t be too tough.

Tools Required

  • Water and gas piping
  • Discharge pipe
  • Fittings
  • Pipe thread compound
  • Pressure relief valve
  • Solder. Ventilation pipe and connections
  • Pressure relief valve.

Getting Started Installing Your New Hot Water Tank

In this example, we’re swapping out a natural gas water heater for an electric water heater. The processes for replacing a propane water heater are identical to those for replacing an electric water heater, and the steps for replacing both are comparable. In any event, when it comes to arranging a water heater replacement, it’s best to be cautious. Call your local department of inspections and inquire as to whether or not you require a permit. Also, be certain that your work is checked by a plumbing or electrical inspector.

Plumbers normally charge between $45 and $65 per hour and can complete the installation of a water heater in a day or as little as 6-8 hours.

Gas water heaters with particular venting systems are also available, although they are more costly. However, because they are more difficult to install, we will not be covering them in this article.

Water Heater Parts and Breakdown

When to get a new water heater

When the tank of your water heater leaks, your water heater is out of commission. An indication that your water heater needs to be replaced is a gradual drop beneath the unit, which commonly manifests itself as a trail of discolored water. This indicates that the steel tank has corroded through and will be unable to be repaired. Other symptoms, such as little or no hot water, are typically indicative of other water heater repair issues that may be resolved by you. If you notice a drop, make a plan to get the water heater replaced as soon as possible.

  • New water heaters are sent with detailed installation instructions as well as several cautions to ensure that the gas, electrical, and other connections are handled properly.
  • However, you should be aware that you will be dealing with natural gas, propane, or electricity, all of which are potentially harmful.
  • And, after you’re finished, get your work examined.
  • You should explain to your local plumbing inspector how you want to install your new connections, including the sorts of materials you intend to use.

Figure B: Connections for Steel and Plastic Pipe

Mr. Fix-It-Up-For-The-Family Water supply pipes in many residences are made of galvanized steel or polyvinyl chloride (CPVC). Replaceable galvanized steel pipes are quite difficult to come by. Using our photo series, we propose that you return the pipes to their original tees and screw on a plastic-lined galvanized nipple before finishing the connections with copper. Plastic tubing should be kept at least 6 inches away from the vent and tank due to the possibility of heat accumulation. Using a specific connection, you may make the transition from plastic to copper.

Flexible copper connectors are less difficult to install than solid copper connectors, which is especially important when the existing pipes and tank inlets do not match up.

If yours does, take extra care not to pinch or kink them when handling them.

Project step-by-step (12)

Turn off the gas to the water heater by twisting the shutdown valve a quarter turn away from the water heater. When the handle is turned off, it should be at a straight angle to the pipe. Also, turn off the main water supply and drain the pipes by opening a tap on the lowest floor of the building. Step No. 2

Drain the water in the tank

Connect a garden hose to the drain valve and use it to drain the water that has accumulated in the tank.

The water will be boiling hot, so proceed with caution! With a pair of wrenches, disconnect the gas line at the neighboring union and remove the pipe from the gas control valve with a pipe wrench to complete the task.

Cut off the water lines

The vent pipe should be moved to the side once it has been unscrewed from the vent hood. After that, using a tube cutter, cut the hot and cold water lines. For galvanized pipe, remove the unions and, if you have them, remove the nuts on the flexible connections as well. Move the old water heater to the side of the room. Step number four.

Attach the relief valve

Teflon tape should be used to seal the threads of the new temperature and pressure relief valve (three turns). With a pipe wrench, tighten it inside the tank until it is completely sealed. Glue a copper discharge pipe to the wall (see Fig. A for routing details). Step number five.

Attach pipe assemblies

Solder fresh copper adapters to 6-in. lengths of 3/4-in. copper pipe and screw the assemblies into the hot water outlet and cold water inlet ports on the top of the tank’s tank’s tank’s tank. Make use of short, plastic-lined nipples to protect your pipes from galvanic corrosion, especially if you have hard water or if they are required by your local building standards. Step 6: Organize your thoughts and feelings about the situation.

Attach the water lines

Solder fresh copper adapters to 6-in. lengths of 3/4-in. copper pipe and screw the assemblies into the hot water outlet and cold water inlet ports on the top of the tank’s tank’s tank’s top. Make use of short, plastic-lined nipples to protect your pipes from galvanic corrosion, especially if you have hard water or if they are required by your local building code. Step 6: Organize your thoughts and feelings about your situation.

Reattach the vent

Reconnect the vent if necessary. Place it securely over the draft hood and secure it with three 3/8-in. No. 6 sheet metal screws to hold it in place. Prepare the holes by drilling them beforehand. Before turning at the first elbow, the vent should rise at least 12 inches vertically from the floor. In this eighth step, you will learn how to use a comma to separate the words “and” and “and not.”

Use two wrenches to attach the gas line

Reconnect the gas line if necessary. Pipe joint compound should be applied to the threaded ends before screwing the first nipple into the gas valve. To minimize straining the valve, use two pipe wrenches at the same time. Reassemble the remaining nipples, concluding with the union at the end of the process (Photo 2). Then, in order to fill the tank, perform these four steps: To check for leaks, perform the following steps: (1) cut off the main water valve; (2) re-connect the water at the main shutoff; (3) open the cold-water valve on the water heater (but do not close it); and (4) turn on a nearby hot-water faucet until water flows out.

Check for backdrafting

Reconnect the gas line if it has been disconnected before. Apply pipe joint compound to the threaded ends of the nipple and screw it into the gas valve for the initial nip. To avoid overstressing the valve, use two pipe wrenches. Reassemble the remaining nipples, concluding with the union at the end of the procedure (Photo 2). Then, to fill the tank, follow these four steps: (1) Close the drain valve; (2) turn on the water at the main cutoff and open the cold water valve to the water heater (keep it open); (3) turn on a nearby hot water faucet until water flows out; and (4) check all of the joints and fittings for water leaks before closing the drain valve.

Check for leaks

Check for leaks by turning on the gas and squeezing a 50-50 combination of dishwashing liquid and water over the connection points. If there are bubbles in the mixture, you have a leak. Joints that are leaking should be tightened or reconnected. When you’re finished, wipe the joints down with a clean cloth. Make an appointment with the plumbing inspector to have them go at your work. Follow the how-to instructions that are included with the photographs to ensure that the connections are secure.

Light the pilot light

The pilot light should be turned on in accordance with the manufacturer’s instructions. (When using an electric water heater, turn on the electricity at the main panel after your work has been checked by the electrical inspector). Once you’ve finished, adjust the temperature to 120 degrees Fahrenheit according to the installation instructions. The pilot light in the new water heater should be lit, then the temperature setting should be adjusted.

Installation Details for Electric Water Heaters

Follow the manufacturer’s instructions for lighting the pilot light. For electric water heaters, turn on the power at the main panel after your work has been checked by an electrician. Finally, according to the installation instructions, set the temperature to 120 degrees F. To begin using your new water heater, turn on the pilot light and change the temperature setting as needed.

How to Dispose of a Water Heater

In this video lesson, Jeff Gorton, an editor at The Family Handyman, will show you how to remove and dispose of a water heater in the proper manner. He will also demonstrate a simple method of transporting a water heater out of your home, even if you are working on your own.

These tips will make your work go faster and easier:

  • To avoid modifying the length of your water, gas, or electrical lines, take note of the height of your existing water heater and get a new one that is the same height
  • On older water heaters, the drain valve (Photo 2) frequently becomes clogged. Please be patient if the water drains slowly. WARNING: The temperature is really high! TIP: Turn off your water heater two hours before you want to use it to enable the water to cool. Water heaters are around 150 pounds in weight. When you’re moving the old one out and wheeling the new one in, you’ll need a strong partner or a dolly to assist you. Ordinarily, garbage collection agencies charge approximately $25 to remove the old one. Before you begin, go to a plumbing supply or hardware store, or a home center, and purchase the equipment and materials seen below. Check the sizes of the water supply pipes (the majority will be 3/4 in., as shown in our photographs) and purchase the fittings that are the proper size. If you have everything you need, you should be able to complete the work in four to six hours (provided there are no major problems!). This safety mechanism, which controls tank pressure and prevents it from bursting, is located in the tank’s pressure relief valve assembly (Photo 4). It is necessary to include a fresh one with each installation. The discharge pipe must be kept clear of impediments in order for the valve to function correctly (see Fig. A). Use 3/4-in. plastic-lined nipples (about $2 each
  • Photo 5 and Fig. A) to attach other metals, mainly copper tubing to the steel tank, in areas where the water is highly mineralized or where it is needed by municipal laws. This has the effect of slowing rusting. In order to avoid heating the tank itself during soldering, solder the copper fittings before screwing them to the tank (Photo 5)
  • Slip couplings should be used to link the existing and new water lines (Photo 6). (Photo 6). They do not have an internal stop, in contrast to normal couplings. Alternatively, you may slip them on, align the copper tubing, then slide them back and center them over the junction
  • However, the new inlets and outlets on the tank don’t always line up with the old supply lines, and vice versa. If required, solder in a pair of 45-degree fittings to ensure that each line is offset. While you’re doing it, you should also replace the old cutoff valve with a new ball valve (Photo 6). The diameter of the vents is determined by the amount of heat produced by the water heater. In order to achieve the ideal draft, you may need to raise or reduce the ventilation size. CAUTION: If you’re not sure whether or not your chimney has a liner, consult with a plumbing inspector. Make gas connections using solid steel pipe (Photo 8) or soft copper tubing with flare fittings (Fig. A). Both are more dependable and less expensive than flexible stainless steel connections, which are not usually allowed in some applications. For the same reasons, rigid copper water supply lines should be used rather than flexible copper water supply lines
  • If your water heater replacement is located in a location where leaking might cause damage to the floor or other elements of the home, lay a pan of an appropriate size beneath it (metal for gas water heaters). a drain tube that connects to a home drain or another suitable site must be installed in the pan (outdoors where permitted). If a leak might cause damage to the flooring, the discharge tube for the temperature and pressure relief valves must also connect to a drain. If routing is a problem, consult with your local plumbing inspector about possible solutions. Special straps should be used to secure your water heater to the wall if you reside in an earthquake-prone location (Fig. A
  • Available at plumbing stores and home centers). If they are necessary, your plumbing inspector will inform you of this. Ensure that the new water temperature setting does not exceed 120 degrees Fahrenheit to avoid scorching

When to Replace a Water Heater

There is a possibility that you can fix your current water heater if it is leaking or not heating up properly. When the time comes, learn how to recognize the indicators that your water heater has to be replaced completely.

How Long Do Water Heaters Last?

According to the manufacturer’s recommended service life, the life expectancy of a water heater is between eight and twelve years on average. That varies depending on the unit’s location and design, the quality of the installation, the maintenance schedule, and the quality of the water. Generally speaking, if your water heater is more than 10 years old, if it leaks at the base of the tank, or if it operates irregularly, it’s time to consider replacing it. You might also choose to upgrade to a more energy-efficient model in order to reduce your energy costs.

Before you begin looking for a replacement, check to see whether an electrical problem, such as a blown fuse or a tripped breaker, is the source of the unit’s failure.

Routine water heater maintenance will help you get the most out of your device, and certain fixes — such as replacing a pressure relief valve or heating element — are quite straightforward to complete.

Troubleshooting Common Issues

One of the most typical issues that arises with a water heater is that the water does not heat up as quickly as you would like it to. This is typically caused by a faultythermostator or a malfunctioning heating element in the boiler. When your water isn’t hot enough, have a look at the following.

Electric Water Heater

  • Check to see that the electricity is connected and that the thermostat has been reset. Flush the heater to remove any sediment that has accumulated in the tank. Ensure that the hot water lines are properly protected. Replacing the heating element or thermostat is a good idea. The thermostat’s temperature setting should be increased.

Gas Water Heater

  • Check to see that the gas is turned on and that the pilot light is lighted. Flush the heater to remove any sediment that has accumulated in the tank. Ensure that the hot water lines are properly insulated. Clean the gas burner and repair the thermocoupler (a safety mechanism that immediately turns off the gas if the pilot flame goes out)
  • The thermostat’s temperature setting should be increased.

Other Common Problems and Possible Solutions

  • If you hear hissing or sizzling noises, it’s possible that sediment has accumulated in the tank. Drain the tank until all of the water has been removed. Remove the components from the oven and place them in a pan filled with white vinegar for up to an hour, scraping off any scale that has accumulated. If the Pressure Relief Valve is leaking, it should be replaced. Water Supply Pipes That Are Leaking: Tighten the fittings. The water should be turned off and the fittings replaced if that doesn’t work.

Water Heater Maintenance

Although today’s water heaters are designed to require little or no care, following these maintenance guidelines may help you extend the life of your water heater. For further information on how to maintain a water heater, see How to Maintain a Water Heater.

  • The majority of newer water heaters are designed to require little or no care
  • Nonetheless, following these maintenance guidelines may help you get the most out of your water heater. Continue reading for additional maintenance advice on how to keep a water heater running well.

When Replacement Is Necessary

If you’re replacing a water heater, you can use the same sort of device as the one you’re replacing. However, you might want to think about upgrading to a bigger tank or a tanklessheater as an alternative. When shopping for a water heater, keep the following qualities in mind:

  • Heaters with a capacity of 40-gallon or 50-gallon are the most commonly encountered
  • In gallons per hour, the recovery rate refers to the number of gallons heated by the heater. In terms of dimensions, depending on where you intend to put the unit in your home, you may require a specific width and height
  • Ratings for energy efficiency: A label on the side of the unit shall display the projected yearly cost of operating the unit in dollars. Models with high energy efficiency can help you save money and energy.

In order to determine if you need to make repairs or purchase a new water heater, look at the nameplate on the side of your present unit. You’ll discover useful information like as the tank capacity, insulation R-value, installation instructions, working pressure, model, and serial number in this section. It is also possible to get information on your electric water heater’s wattage capacity and voltage on the nameplate of the heater itself. If you need replacement components or a new water heater, you may use this information as a starting point in your search for them.

  • What plan do you have for getting rid of your old water heater? Check your local codes to see how such equipment should be disposed of. Will you be able to manage the device on your own physical terms? Water heaters are large and hefty appliances. You’re going to require assistance
  • Do you have all of the tools you’ll need to complete the job? Water heater installation necessitates the use of adjustable wrenches, screwdrivers, a hack saw, and pliers among other tools. If your copper pipe installation necessitates the use of a propane torch, you may also require one. Do you have the necessary time to complete the task? Once you begin replacing a water heater, you must see it through to completion.

Please see our articles on How to Install an Electric Water Heater and How to Install a Gas Water Heater for further information on how to replace a water heater in greater depth.

How to Install an Electric Water Heater

Installing a new electric water heater can allow you to save both money and electricity. How to do it is demonstrated in our video and step-by-step instructions. Please keep in mind that product pricing, availability, and item numbers may differ from market to market.

Before You Begin

Examine your water heater to see whether it need replacement or if routine maintenance would suffice. There might be a problem with the heating element or another type of maintenance issue if you are not getting hot water. Before committing to a complete replacement, conduct a brief maintenance inspection. If you have water on the floor or on top of the unit (as opposed to water leaking from a supply line above the unit), you’ll most likely need to replace your water heater as soon as possible.

A excellent time to think about upgrading or reducing your electric water heater is when your family’s size has increased or decreased.

If you’re not confident in your ability to complete water heater installation, hire a professional.

Caution The water pressure in your house is critical for all of the equipment that use water. A decrease in pressure reduces the stress placed on plumbing systems and helps to increase the lifespan of appliances and fixtures.

Water Pressure

The water pressure in your house is critical for all of the equipment that use water. A decrease in pressure reduces the stress placed on plumbing systems and helps to increase the lifespan of appliances and fixtures. Check the water pressure in your house by attaching a pressure gauge to an exterior spigot. The optimal PSI ranges from 50 to 60 PSI. if the water pressure in your house is more than 80 PSI, use the pressure-reducing valve located near the main water shut-off to decrease the pressure.

If you don’t already have a pressure-reducing valve in your house, a professional can install one for you.

Expansion Tank

Decide the type of expansion tank you’ll require. It is possible to reduce surplus pressure in the lines of a closed system using thermal expansion tanks. A 2-gallon expansion tank can be used with water heaters that hold up to 50 gallons of water. For water heaters that hold up to 100 gallons of water, a 5-gallon expansion tank should be used. For for size information, see the manufacturer’s instructions. In most cases, the expansion tank is connected to the cold-water supply pipe near or above the water heater.

They simply slot into the pipe without the need for soldering.

Soldering paste should be applied to both the pipe and the fittings before assembling.

In order for an electric water heater installation to be functional, the pressure in the expansion tank must equal the pressure in the main water supply.

Removing the Old Water Heater

The following steps will walk you through the process of installing an electric water heater. When transporting a water heater, employ a helper, an appliance dolly, or a hand truck to ensure that the device is not damaged.

Preventing Scalds

Even with the temperature gauge set at 120 degrees, the risk of scalds remains a possibility. Children, the elderly, and individuals with delicate skin are particularly at risk of developing skin cancer. Consider adding thermostatic mixing valves to keep people safe from being hurt. Installed at the point of use faucet, fixture, or appliance, a thermostatic mixing valve regulates both the volume and temperature of water by connecting to both the hot and cold water supply lines at the same location.

How to Replace a Water Heater

Article in PDF format Article in PDF format A water heater is a necessary home device that is responsible for supplying hot water to the entire household. The moment has come to replace a water heater if water is beginning to seep from the bottom of the unit. When there is leaking, there is corrosion and wear within the tank. Water heaters typically survive at least 10 years, with some remaining in good condition for as long as 20 years or more. Immediately replace any leaky water heaters to avoid flooding and further clean-up costs.

  1. 1 Determine when it is necessary to replace your water heater. Water heaters typically have a lifespan of 8 to 15 years, depending on the model. In the event that your water heater ceases to function, there is a considerable probability that it will need to be replaced.

  • 2 Make a phone call to your local plumbing inspector. To find out about the unique regulations for your area and if you need to obtain a permit prior to changing your heater, it is a good idea to contact your local plumbing inspector.
  • Provide a detailed description of the new water heater, as well as any supplies that you want to utilize in the installation process. The plumbing inspector may be able to provide you with some valuable criticism or ideas that will be beneficial to your installation. The services of a plumbing or electrical inspector might be requested if this is your first time replacing a water heater and you are concerned about the safety of your job.
  • Provide a detailed description of the new water heater, as well as any supplies that you plan to utilize in the installation process. A valuable piece of feedback or suggestion from the plumbing inspector may be beneficial to you throughout your installation
  • Nevertheless, it is not guaranteed. The services of a plumbing or electrical inspector might be requested if this is your first time replacing a water heater and you are concerned about the safety of your installation.
  • Screwdriver, adjustable wrench, pipe wrench, tube cutter, wire stripper/cutter, electrical tape, plumbers tape, carpenter’s level, tape measure, rags, and safety glasses are some of the tools you will need. Construction materials include a new gas (or electric) water heater, water and gas pipes and fittings, solder, a pressure relief valve, discharge pipe, pipe thread compound, venting pipe, and connections
  • And
  1. 1 Shut off the gas supply to the house. It is necessary to switch off the gas supply in the first instance. Alternatively, you may use an adjustable wrench to turn the gas shutdown valve by hand
  2. But, this will take longer.
  • In order to ensure that the gas is turned off, the valve handle must be at a right angle to the pipe. Check to see that the pilot light has been turned off. Before proceeding, check for the existence of gas by smelling it. If you’re replacing an electric heater, remove the fuse or turn off the circuit breaker to turn off the electricity to the water heater
  • Otherwise, follow the manufacturer’s instructions.
  • 2 Remove the tank’s contents. Turning off the water supply by turning the shutdown valve on the cold water supply line will switch off the water supply.
  • Drain the tank by turning on a hot water faucet on the lowest floor of the house to begin the process. Because of this, the tank will be lighter and more portable. Gently open the drain valve on the tank by connecting a hose to it and slowly opening the valve. Ensure that the water drains into a nearby drain or pail
  • Because the water may be boiling hot, exercise extreme caution.
  • Start by turning on a hot water tap on the lowest floor of the house to drain the tank completely. Because of this, the tank will be lighter and simpler to transport
  • Gently open the drain valve on the tank by connecting a hose to it and slowly turning the knob. Ensure that the water drains into a nearby drain or bucket. The water may be boiling hot, so proceed with care.
  • To disconnect the gas line at the union or flare fitting, use two pipe wrenches to pry it apart. Use a pipe wrench to carefully remove the pipe from the gas control valve and discard it. If you have an electric water heater, you may simply turn off the power and separate the hot and cold water lines from the heater. It may be necessary to cut the pipes using a tubing cutter or a hacksaw if they have been soldered into place before. It’s important to make sure the cuts are as straight as possible. Remove the screws that hold the vent to the water heater together and the vent will come away from the water heater. Vent pipe should be moved to one side.

Remove the screws that link the vent to the water heater and the vent will come apart. Vent pipe should be moved to the side.
  • You may want assistance with this task since older water heaters are sometimes clogged with silt, making them quite heavy. When replacing a water heater that is located in the basement, consider renting an appliance dolly to assist you in moving the new heater and the old heater up and down the stairs. Get rid of your old water heater in a safe and legal manner. For more information on how to recycle a water heater, contact your local waste management department or sanitation agency for assistance. The majority of states already have legislation restricting the disposal of appliances such as water heaters in landfills or dumps.
  1. 1 Install the new water heater in its proper location. Remove any standing water from the floor and then place the new water heater in its proper location.
  • To align plumbing sites with suitable pipes, turn the heater around so that they are aligned with the relevant pipes. To verify that the heater is sitting properly, use a carpenter’s level to check its alignment. If necessary, use some wooden shims to raise or lower the level
  • 2Install the temperature and pressure relief valves in the appropriate locations. Install the replacement temperature and pressure relief valve (supplied with your water heater) by wrapping a couple of thicknesses of Teflon tape over the threads and tightening it down with a pipe wrench or pliers. 3 Attach the discharge drain pipe to the sewage system. Connect the pipe assemblies together. Two 6 inch pieces of 3 4 inch (1.9 cm) copper pipe are needed, and each one will require a new adaptor to be attached to it.
  • Solder the adapters to the pipes on a work table that is away from the water heater, since you don’t want to put a heat source too close to the water heater tank. The adapters should be attached to the hot water output and cold water input on top of the tank with pipe joint compound or Teflon tape to prevent leaks. You may also be required to install plastic-lined nipples to the bottom of each pipe assembly, depending on your local plumbing regulations. In addition, it helps to avoid galvanic corrosion, which is particularly significant in places with hard water.
  • 4 Attach the hot and cold water pipes together. For the purpose of connecting the hot and cold water lines, you must either cut or lengthen the existing pipes so that they reach the newly connected ones.
  • Using copper slip couplings or dielectric unions (to avoid electrolysis), join the two ends of the pipe together. If you are unable to line the old and new pipes properly, you can link them together using sections of flexible copper tubing or 45-degree elbows.
  • 5Reattach the vent if necessary. Take hold of the vent pipe and place it just above the draft hood on the water heater, if possible. Use three 8-inch (1.0-centimeter) sheet metal screws to hold it securely in place. 6 Connect the gas line to the meter. To prepare the threaded ends of the pipes for reassembling them, clean them well with a wire brush and a rag and then add a little amount of piping compound to each of them.
  • Then, using two pipe wrenches, tighten down the first nipple into the gas valve, and continue to reassemble the other fittings. The union fitting should be the final connection, as it is responsible for connecting the new line to the existing one. It is possible to switch on the gas supply valve after this has been connected. For electric heaters to be connected to their power source, connect the power cables and ground wire to the junction box on the wall.
  • 7 Look for any leaks. By immersing a sponge in soapy water (prepared with dishwashing detergent) and pressing it against each freshly connected joint on the water heater, you can check for leaks.

  • 8Refill the tank with water. To begin filling the tank, turn on both the main water supply and the cold water supply valves at the same time. Activate the hot water faucet located at a distance
  • At first, nothing may come out or the water may sputter. It is considered to be fully replenished after a continuous stream of water is flowing from the faucet
  • 9 Restore electricity to the system. Turning on the new water heater is as simple as lighting the pilot and turning the control knob to the “on” position. Preferably, the temperature should be set between 110 and 130 degrees Fahrenheit.
  • Reinstall the fuse or reset the circuit breaker in the power panel if your water heater is electric
  • Otherwise, turn on the water heater by turning on the faucet.

Has it been more than ten years since you last replaced your water heater? It appears to be beginning to exhibit symptoms that it will fail in the near future. What follows are some of the reasons why you should consider replacing the appliance before it becomes fully useless.

Give Yourself Time to Research Replacement Options

Maybe you’ve had an electric storage water heater for the most of your life. If your present unit fails, you will almost certainly replace it with one that is identical in appearance. Natural gas or solar electricity, on the other hand, may be the most appropriate fuel source in your scenario. Furthermore, tankless technology has the potential to save you a large amount of money on your water heating bills. It’s unlikely that you’ll have time to investigate these alternative solutions, which might increase performance and efficiency over the next 10 to 20 years if your water heater dies unexpectedly.

That is why, if your water heater is exhibiting symptoms of wear and tear, we recommend that you replace it before it fails completely.

Avoid an Inconvenient Emergency Replacement

Trying to squeeze every last drop of hot water out of your water heater before replacing it may be a good idea, but waiting until it completely fails might be extremely annoying. In the end, no one wants to be forced to take ice cold showers for a day or two while they are waiting for a new water heater to arrive and be installed. Planning ahead of time, on the other hand, enables for a rapid and convenient installation that can be completed on your time schedule.

Prevent Water Damage

Water heaters can go out with a bang, as in, they suddenly quit operating one day without warning. Some water heaters, on the other hand, fail catastrophically when water breaks through the tank’s walls and floods the basement, garage, or utility room where the water heater is located. Maintaining your water heater on a regular basis throughout the years will help you prevent this catastrophe. Every few years, once it rusts through, a sacrificial anode rod within the tank must be changed. This rod is meant to draw corrosive substances before they damage the water heater itself.

Lower Your Utility Bills

If you make the appropriate decision in a new water heater, your investment will pay for itself immediately in decreased utility bills. Given that water heating is the second most expensive energy bill after space heating and cooling, it makes financial sense to invest in a high-efficiency model that will last longer.

Signs that You Should Replace Your Water Heater Soon

If you detect any of the following indicators of imminent failure, it’s time to start looking for water heater replacement options:

  • There is no hot water. Strange noises are emanating from the water heater
  • Water that is red or brown in color is gushing from the faucet. Corrosion seen on the water heater tank’s surface
  • There are puddles of water all around the tank.
