How To Open Plastic Drain Valve On Water Heater

You Can Drain Water Heater – 4 Easy Steps

Mineral build-up in your water heater system, particularly while the hot water is flowing, might result in reduced water pressure. It is possible that your pipes require drain cleaning to clear up obstructions regardless of the temperature. You should inspect your water heater if your water pressure has not improved after recent maintenance on your drains. Your plumber will inspect your water heater for scale buildup and will flush your system to remove any sediment that has accumulated. They will also inspect all of the pipes going to and away from the water heater to ensure that they are free of obstructions and capable of moving enough water.

Drain Water Heater

Step one: Turn off the gas water heater by turning the control knob to the off position. Electric water heater: Disconnect the electricity at the circuit breaker panel. Make very certain that you have turned off the correct breaker. If the power is turned off while the tank is being emptied, the heating elements will blow and will need to be repaired or replaced. If you are unable to locate the water heater breaker, turn off all of the double breakers in the house. In your house, turn on a hot water faucet and leave it running until the water becomes cold.

In addition, hot water will destroy your grass and other plants.

  • Step Three Remove any kinks from the hose and position it outside.
  • This will clear the valve of any silt that may have accumulated inside it.
  • The water shut-off valve should be situated above the water heater on the cold water line, and it should be easily accessible.
  • Open your faucet’s hot water side by turning it on.
  • Using an earlier model pressure relief valve to allow air into the tank is a good idea if your system is equipped with one.
  • Relief valves that are more recent in design will not lock open.
  • Ca calcium deposits accumulate in the tanks of most water heaters as a result of hard water.
  • The deposits can travel through the water lines and block the faucets, appliances (dishwasher, clothes washer), and under sink shut off valves when the tank is disturbed, such as when it is drained and refilled.
  • If there is an issue, unclogging this faucet is a straightforward process.
  • If you’re having trouble getting the water to drain, turn off the hotwater side of your kitchen faucet and try again.

Replacing your water heater’s water supply while leaving the drain valve open is the correct procedure. When the water is gushing down the drain hose, turn off the water and open the hot side of your kitchen faucet to let it out.

Water Heater Draining Problems

What should I do if my water heater drains for a time but then stops and I know the tank is not empty? Check to see if somebody switched off the hot water side of your kitchen faucet while you were away from the sink. 2. It must be able to drain with air. 2. Debris, rust, and calcium deposits may have accumulated in your drain valve. Refill the tank while leaving the drain open and the faucet closed if the tank has only emptied a little amount. This should be accomplished by the water pressure pushing the particles out of the drain pipe.

  • If a significant amount of water has been drained from the tank, you can attempt the measures listed below instead of replenishing the tank.
  • Place a small bucket under the drain to catch any spills.
  • Be prepared to switch off the drain valve until the hose has been reattached.
  • If you are attempting to drain a water heater and it becomes clogged, you may use the fill/supply line from a washing machine to force the debris out of the drain.
  • Connect one end of the hose to the water heater drain valve and the other end to a garden hose for drainage.
  • Make certain that your drain valve is open.
  • Firstly, disconnect the hose from the faucet and allow the tank to empty.

My drain valve keeps becoming clogged, and I’m unable to dump my tank.

With a set of hand trucks, you could disconnect the plumbing, gas, and electricity, and then roll the water heater to the outside.

When you use a ball valve, you can empty the water heater.

Even if you are replacing your old water heater, you may still remove the tank and put it on your new water heater after the old tank is completely empty.

It will continue for many more years.

How to Remove a Broken or Faulty Drain Valve

If you wish to replace a drain valve that has been damaged or malfunctioning, you’ll need the following tools:

  • Screwdrivers/needle-nose pliers
  • Hacksaw blade
  • Self-tapping threaded inserts for plastic
  • Hosepipe
  • Large bucket
  • Hammer Wrench/tongue-and-groove pliers with an adjustable wrench

Although removing the valve is not as simple as it appears, it is not unduly difficult. Plastic drain valves can be difficult to remove since they are prone to breaking off during the procedure. Because of this, you must use caution while dealing with one in order to avoid more harm. Remove the drain valve only after you have ensured that the valve that supplies the coldwater supply into the hot water heater is turned off. In addition, the water faucets should be turned off. If at all feasible, you should empty your water heater before proceeding.

In addition, you should inspect and repair your anode rod if necessary.

for a step-by-step procedure on how to replace anode rods There are three different approaches you might take to the removal.

Method 1 – Unscrew the Plastic Drain Valve

Using a pair of channel lock pliers, slowly twist the drain valve in a counter-clockwise direction to try to release it from the pipe. In order to make the operation go more smoothly, you should gently remove the plastic drain valve without damaging it.

Method 2 – Cut the Drain Valve Off

Take your hacksaw blade and make two cuts across your nostril until the nipple starts to come loose. Avoid cutting the threads on the water heater if at all possible. Finally, using a tiny screwdriver or needle-nose pliers, remove any leftover components from the assembly.

Method 3 – Remove a Broken Drain Valve

Another way is to use a tapered threaded insert for plastics that has a tapered threaded insert.

Simply fit the inserts into the nipple and unscrew the nipple. If, on the other hand, you’re dealing with a plastic valve in an old water heater, this method may not be effective.

How to Replace a Water Heater Drain Valve

Replace a water heater drain valve with the following materials if the old one is damaged or broken.

  • Replace a water heater drain valve with the following materials if the existing one is damaged or broken.

A step-by-step procedure for changing your valve is provided below:

Step 1:Switch off the power supply.

Circuit breakers must be turned off in order to ensure the safety of anyone using the circuit breakers. If your water heater is powered by natural gas, set the regulator valve to the “pilot” position. Make use of the hot water stored in the tank to wash dishes, clothing, and take showers in order to prevent water wastage. Electric water heaters should be turned off by turning off the circuit breaker in the electrical panel box.

Step 2:Turn the cold water supply valve off.

Circuit breakers must be turned off in order to ensure the safety of anyone using the power supply. Using a natural gas water heater? Make sure you have the regulator valve set to “pilot.” Make use of the hot water stored in the tank to wash dishes, clothing, and take showers in order to avoid wasting any water. Electric water heaters should be turned off by turning off the circuit breaker in the electric panel box.

Step 3: Drain the water heater

The garden hose should be connected to the drain valve and directed outside the ground or to a floor drain. Open the drain valve and the hot water faucet in a neighboring sink if they are not already open. If the tank is not emptying properly, you will need to open the pressure relief valve, which is situated on the tank’s uppermost section (or side). Allow the water to run out once you’ve completed this step. Sticking a screwdriver into the drain valve hole and trying to break up the sludge will work if the valve is jammed with sediment.

Depending on the size of the water heater, it might take up to 30 minutes to completely drain the water.

Step 4: Remove the old drain valve.

You’ll need to remove the old drain valve after the water heater has been emptied. Carefully unscrew the drain valve in a counter-clockwise motion with a pair of channel lock pliers, being cautious not to damage the drain valve. If the channel lock pliers are ineffective in removing the seal, you may need to use a bigger 18′′ pipe wrench or breaker bar to complete the job. If the drain valve fails, you’ll need to remove the drain valve’s remains from the drain valve port, which can be difficult.

The port should be cleaned to prepare it for the new drain valve once all of the remains have been removed.

Step 5:Install the new drain valve.

To begin, wrap the thread with Teflon tape to prevent it from fraying. Use tape to the right in the direction in which the drain valve is treaded so that the tape tightens as the drain valve is tightened, and then tighten the drain valve. If desired, a light layer of pipe dope might be applied. After that, please place the new drain valve into the hole and tighten it with a wrench to complete the process. Place the valve in the exact same place as the previous one, tight and pointed downwards, before replacing it.

Keep in mind that you should not overtighten the connections while installing a plastic drain valve. It is possible that the valve will break off due to the considerable effort used. It might not happen right away, but it will eventually find its way around the corner.

Step 6: Turn on the Cold Water Supply

It is now necessary to re-connect the cold water supply in order to replenish the tank. If you notice any leaks while the tank is full, you should tighten the drain valve gently if necessary. Make certain that the tank is completely filled before turning the power back on. As the level of the water in the tank rises, air will be forced out via the open hot watertap. Close the hot water tap once the water has been released.

Step 6:Turn on the gas supply or power.

In order to replenish the tank, you must switch on the cold water supply again. Keep an eye out for leaks and progressively tighten the drain valve if any are discovered when filling the tank with water. Fill the tank up completely before re-connecting the electrical supply. – As the level of the water in the tank rises, air will be forced out through the open hot water tap. Close the hot watertap after the water has exited it.

Please keep in mind that this content may contain affiliate links. This means that, at no additional cost to you, we may gain a small profit on purchases made via our links. If you’re intending on repairing your drain valve, you might want to make a quick trip to your local hardware shop and pick out a replacement valve while you’re waiting for the tank to cool down before you begin. Otherwise, purchase a replacement valve online so that it will be available for you to install over the weekend or on whichever day you decide to replace the valve.

Choosing the Right Replacement

When it comes to purchasing a replacement drain valve, you have a few of options to consider. Valves are available in a variety of materials, including metal, composite, and plastic. Plastic is the least expensive, but it is also the least dependable of the three materials. The composite material is preferable for your anode. Brass drain valves, on the other hand, are the best choice since they last the longest and can withstand considerably greater temperatures than a composite or plastic drain valve.

The advantages of ball valves are numerous, but because you will be using it to drain sediment, you may choose to avoid the somewhat increased danger of clogging that comes with them.

If You CAN Drain the Tank

When the hot water tank has been completely drained, changing the drain valve is the most effective and safest method. Before you begin, you will need to turn off the electricity and gas (if applicable). Although you may drain the water sooner if you wear protective equipment to avoid splashing, it is better to allow it to cool for 12 to 24 hours before starting the procedure. When you’re ready to start, turn on the T P valve and turn off the cold water intake valve at the same time. Connect a hose and empty the toilet as you would normally do during a normal flush.

  1. Wrap a piece of Teflon tape over the threads of the new valve to protect them from corrosion.
  2. Then, using your wrench, tighten it down to the original position.
  3. Using a paper tower to wrap around the drain valve is an effective method of detecting moisture.
  4. You can check the flow of hot water by turning on a nearby hot water faucet.

Close the T P valve and turn off the water supply after the waster is flowing gently out of the faucet. Return the water heater’s electricity and gas sources to normal operation. Finally, dispose away the old valve and enable the tank to carry out its function without interruption.

If You CAN’T Drain the Tank

When the hot water tank has been completely drained, it is the safest and most effective time to replace the drain valve. The electricity and gas (if relevant) supplies must be turned off before you begin work. Although you may drain the water sooner if you wear protective equipment to avoid splashing, it is recommended to allow it to cool for 12 to 24 hours before draining it. As soon as you’re ready to start, turn on the T P valve and close the cold water intake valve. Hook up an appropriate drain hose and drain the toilet just as you would normally do.

  1. Wrap a piece of Teflon tape over the threads of the new valve to make it easier to install later.
  2. Then, using your wrench, tighten it down on the new valve.
  3. Using a paper tower to wrap around the drain valve is an effective method of identifying moisture.
  4. It is possible to verify the flow of hot water by running it from an adjacent cold water faucet.
  5. Make sure that the water heater’s electricity and gas are restored.

Types

Drain valve made of brass Plastic and brass drain valves are the most common types of drain valves found on tank-type gas and electric water heaters, respectively. We recommend purchasing a water heater with a brass drain valve rather than a plastic drain valve because brass drain valves are stronger and more durable. Plastic drain valves are more prone to damage, particularly around the threads, making them more likely to leak. If your water heater has a built-in plastic valve, you may want to consider replacing it with a brass valve to improve the overall performance of the unit.

A durable tamper-resistant brass drain valve with the standard size of 3/4″ is used almost exclusively by some manufacturers, such as AO Smith, in practically every water heater they produce.

Why draining

There are a variety of reasons why a water heater should be drained:

  • Changing a heater or other items that need the removal of the unit’s contents
  • Flushing as a result of silt accumulation
  • Winterizing is the process of preparing your heater for the winter by emptying its tank. The drain valve on the water heater is leaking
  • A blockage has formed in the drain plug. The drain valve is not working properly

How to drain a water heater

It is necessary to empty the device while replacing a heater or other components. Floating owing to an accumulation of sediment Draining the tank of your heater is an important part of winterizing it. The drain valve on the water heater is leaking. A blockage has built up in the drain plug. Because the drain valve has failed, the water cannot drain.

  • If your unit is powered by electricity, switch off the electricity at the breaker for your electric unit, or set the gas control valve to the pilot position or the thermostat dial to OFF if your unit is powered by gas. Open neighboring hot faucets and leave them open to let all of the water to run until the temperature drops to 100 degrees or less. The incoming pipe’s primary shut-off valve should be switched off. Open the TPRvalve (which is situated on the unit’s top)
  • Using a hose, connect the drain valve to a sufficient drain or to the outside of the house
  • Use the other end of the hose to terminate in the same location. Inspect every connection to ensure that it is secure, and that the flow is routed away from humans. Open the drain valve to enable the water that has accumulated in the tank to drain
  • As soon as the heater has been drained and the flow has stopped, unplug the hose from the valve and close it

It is important to note that before refilling the heater with water, make sure that the drain valve is completely closed. It is advised that the water heater be emptied and cleansed every 6 months or once a year to ensure optimal performance. Because the valve is meant to be positioned at a specific height above the tank’s bottom, even if you try to completely drain the unit, there will always be some water remaining in the tank after installation. The majority of the hazardous and corrosive particles will be contained in the water remaining at the bottom of the tank, which will cause the drain valve to get clogged once more.

How to replace a drain valve fast and easy

Drain valve made of plastic It is quite simple to replace a drain valve on an electric or gas heater, and it necessitates no specific equipment or abilities. It is critical that the water within the tank is kept cold so that it does not burn the operator’s skin. You can either completely or partially remove the water from the tank in order to replace the component. The valve may need to be replaced for a variety of reasons, including leaking, clogging, and failure.

  • If your heater is electric, turn off the electricity at the circuit breaker, or switch the gas valve to pilot if your heater is gas. Close the main water supply valve, which is conveniently positioned near the heater. Make sure all of the faucets in the home are turned off, since the suction formed inside the tank will prevent water from leaking out and causing damage to the house. Applying Teflon tape or pipe sealant to the valve threads will prepare the new drain valve for installation. Install a brass or ball valve in lieu of the plastic valve that came with the water heater
  • This will make the water heater more dependable and durable over time. Place the bucket underneath the valve to capture the water that is escaping
  • Make use of the adjustable wrench or big groove-joint pliers to unscrew the old water heater drain valve. If there has been a buildup of pressure inside the tank, you may experience a sudden influx of water after removing the old valve. Install the replacement valve as soon as possible, twisting it clockwise to prevent the heater from losing too much water

Drain valve problems

All heaters are equipped with a drain plug located at the bottom of the device. Having the tank in this place makes it simple to do routine maintenance and to drain the tank. However, there are certain issues: the valve might be broken or leaking, for example. If the drain valve is not there, it may be difficult to remove the sediment deposits that have accumulated at the bottom of the tank. It is possible that the valve will be unable to function if it is damaged. A leak indicates that there is an issue that has to be addressed and resolved.

How to unclog a water heater drain valve

In most cases, a blocked water heater drain valve may be identified by the fact that nothing comes out, water flows irregularly, or water trickles out instead of flowing continuously. The accumulation of silt within the valve is the most common cause of the stop mechanism becoming inoperable. Mineral deposits will begin to be extracted from the bottom of the tank as the water warms and finally becomes warm and hot.

If there is no regular maintenance, silt building can become quite considerable, obstructing the drain valve and negatively impacting the performance and efficiency of the system dramatically. There are a number of approaches that may be utilized to resolve this issue:

  • Take into consideration the fact that in certain cases, when the mineral accumulation is not significant, it just takes time for the sediments to be pushed from the water pressure, become loose, and go farther via the drain
  • If the accumulation is substantial, attempt to dislodge the debris with a strong wire or screwdriver to see if it can be removed. Insert the tool into the drain valve and slide it back and forth and in a circular motion to clear the drain. Even if you have cleared away part of the material, the valve may become clogged again, so repeat the procedure. As an alternative to using a wire, you may utilize the back-flush method, which involves attaching the garden hose to the water faucet and then directing the water into the tank, which will force the sediments away from the valve and finally remove any clogs
  • Using the preceding instructions, remove the drain valve (particularly if it is made of plastic) and replace it with the 3/4-inch drain valve “A ball valve is a valve that has a ball in it. Make use of two 3/4 “Dielectric nipples are used to keep rust at bay. The valve has been increased in size and strength, and it will be beneficial in the future by preventing sediments from clogging the valve.
See also:  How To Drain Sediment From Hot Water Heater

Keep in mind that, when the mineral accumulation is not severe, it may only take a short period of time for the sediments to be forced out by the water pressure, become loose, and go farther down the drain. The stiff wire or screwdriver can be used to dislodge the debris if the accumulation is significant. Move back and forth and in a circular motion with the tool to insert it through the drain valve. You should repeat the procedure even if you have cleared away part of the trash since the debris might re-block the valve.

As previously said, remove the drain valve (particularly if it’s made of plastic) and install the 3/4-inch hose fitting “Ball valve is a type of valve that has a ball within it.

With its increased size and strength, the valve will be more effective in the future, preventing sediments from blocking the system.

How to remove a W/H plastic drain valve?

Remove the water heater from the circuit. To relieve the pressure, turn on a water faucet. Connect the hose to the drain valve. Open the drain valve and let the water to flow until it air locks. Or as near to it as you possibly can get it. By placing your finger over the hose and feeling for pressure build, you can ensure that there is no pressure flowing through the valve. If there is none or only a little amount, proceed. Keep it near the heater. A bunch of rags, a flat-head screw driver, huge channel locks, and a replacement drain valve that has already been taped and doped are all that are needed.

  1. If it breaks soon, stuff a cloth into the hole created by the flat-head screw driver and tighten it.
  2. Then take your flat head and your channel locks and softly chisel the plastic away from the steel, just enough to break the plastic free.
  3. Then, swiftly unscrew the old brass drain valve and pull out the rag and the remainder of the threads it was attached to.

How to Unclog a Drain Valve: 7 Ways to Get the Water Flowing

As an Amazon Associate, we receive a commission on qualifying purchases made via our links. Find out more. When your water heater won’t drain, the most likely reason is that the drain valve has become clogged. This is usually the result of an excessive amount of silt accumulating within the tank. During the heating process, the minerals present in the water separate and settle to the bottom of the water heater. If the sediment in the tank is not removed on a regular basis, it will not only diminish the effectiveness of the device, but it can also clog the drain valve, causing the water to become trapped within the water heater.

When it comes to the degree of your blockage, it might range from a slight nuisance to a severe problem. If left ignored, it will eventually need the purchase of a new water heater since the sediment will corrode the interior of your tank and cause an unrepairable leak.

7 Methods to Unclog a Drain Valve

As an Amazon Associate, we receive a commission on qualifying purchases made via our link. Get to Know Us a Little Bit Better! Clogged drain valves are the most common reason of a water heater that will not drain. As a result of excessive sediment build-up within the tank, this is a common occurrence. During the heating process, the minerals present in the water separate and fall to the bottom of the water heater. Not only will the silt diminish the efficiency of the device if it is not emptied on a regular basis, but it may also clog the drain valve and cause the water within the water heater to get trapped.

This problem, if left ignored, will eventually need the purchase of a new water heater, as silt will tear down the inside of your tank, resulting in an unfixable leak.

  1. Turn off the fuel supply for your water heater (electric: turn off the power to the water heater). Turn off the circuit breaker (in the case of gas, turn the on/off control knob to the off position)
  2. Drainage should be connected to the drain valve and the valve should be OPENED. DEPRESSURE IN THE TANK: OPEN a hot water faucet inside your home (and leave it open) to allow the negative pressure to escape
  3. It is unlikely that your valve is clogged if the water drains and turns clean. Clogged valves cause the water to dribble or not drain at all
  4. This indicates that the valve is clogged.

Caution is advised since there is a strong likelihood that the water in the tank is extremely hot. To avoid being burnt in this situation, you should take appropriate safety steps before proceeding. When attempting to drain a water heater, always use work gloves and safety eyewear to keep yourself safe. Additionally, the water should be allowed to cool before being drained. There are numerous techniques for cooling the water inside the tank, which are as follows:

  • The water in the tank may be quite hot, so proceed with caution. To avoid being burnt in this situation, you should take the necessary safety steps. When attempting to empty a water heater, always use work gloves and safety eyewear. The water should be allowed to cool before it is drained as well.

How to Unclog a Water Heater Drain Valve

There are a variety of methods for draining a clogged water heater tank, and the degree of the blockage will play a significant factor in selecting which approach is most effective. Begin with the simplest item on the list and work your way down to the more difficult items. Take note that the water in the tank is most likely quite hot, so take precautions to avoid getting burned by following the safety guidelines stated above. Before you begin, make sure that the water heater’s power supply is turned off.

Wait

If your drain valve is clogged, the first thing you should do is to wait it out. Occasionally, the weight of the water within the tank will be sufficient to dislodge the blockage on its own. Here’s what you should do:

  • Continue to leave the drain valve open while the hose is connected. Close all hot water faucets in the home except for one. Continue to wait for an hour or so to observe whether the tank begins to drain.

  • As soon as you have connected the hose to the drain valve, stand firmly onto the hose around 2 feet away from your water heater
  • If the sediment is the source of the blockage, an air bubble will be blasted back into the tank, clearing the obstruction and unclogging the valve. You shouldn’t be surprised if the drain valve becomes clogged once more when you are attempting to drain the tank. Basically, you just have to keep repeating the process until the tank is totally emptied.

Back Flush

If none of the procedures listed above were successful, it may be necessary to attempt back cleansing your water heater. Here’s how it’s done:

  • Fill the hose with water from a washing machine. On both ends of these hoses, there is a female connector. DON’T forget to close the drain valve and attach one end of the wash machine hose to the valve. Use a garden hose to connect the other end of the hose to a nearby washtub faucet (washtub faucets are commonly threaded) or to an outside faucet (and connect the garden hose to an outside faucet)
  • Turn the water supply to the faucet on. OPEN the water heater’s drain valve and allow the water to flow into the tank for 10 to 15 seconds
  • OPEN the water heater’s drain valve and allow the water to flow into the tank
  • In order to unclog the valve, water from the hose should be used to drive the silt away from the valve. Close the drain valve and turn OFF the water at the faucet to prevent a puddle from forming. Unplug the hose from the faucet (leave the line attached to the drain valve, or use a garden hose to drain the tank)
  • OPEN the water heater drain valve and allow the water to drain from the tank. It’s possible that your blockage is too severe or that your drain valve is malfunctioning, in which case you’ll need to replace your drain valve.

Fill the hose with water from your washing machine. Female connectors are provided on both ends of these hoses. CLOSE the drain valve and connect one end of the wash machine hose to the valve. (See illustration.) Use a garden hose to connect the other end of the hose to a nearby washtub faucet (washtub faucets are commonly threaded) or to an outside faucet (and connect the garden hose to an outside faucet). Make sure you have water flowing via the faucet. FOR TEN TO FIFTY SECONDS, OPEN THE WATER HEATER’S DRAIN VANITY AND ALLOW THE WATER TO FLOW INTO THE TANK In order to unclog the valve, water from the hose should be used to force the silt away from the valve.

Unplug the hose from the faucet (leave the line attached to the drain valve, or use a garden hose to replace the hose); OPENS the water heater drain valve and allows the water to flow from the tank It’s possible that your blockage is too severe or that your drain valve is malfunctioning, in which case you’ll need to replace the drain valve.

  • A replacement drain valve (preferably brass) should be purchased. Tape the threads of the replacement drain valve with Teflon tape. Check to make sure that ALL of the faucets in your home are closed. When this happens, your water heater will generate a vacuum, which will prevent the water from “pouring out.” Place a bucket and a few towels beneath the drain valve to catch the water. To open the drain valve, use an adjustable wrench to turn it. Remove the drain valve one turn at a time. Keep in mind that some water will be dripping from your tank. Even if your tank is completely blocked, you will very certainly have some water escaping from it. If, on the other hand, the problem is a defective drain valve, you will almost surely have water. Insert the replacement drain valve as soon as possible. This shouldn’t take more than a few seconds. To drain your tank, just connect it to the new drain valve using a garden hose
  • We propose that if you’re going to go to the trouble of changing your drain valve, you consider replacing it with a ball valve to save time and effort (see below). Your drain valve will never clog again, and you will never have to worry about it again.

Many water heaters are equipped with low-cost plastic drain valves. You should replace it with a high-quality brass valve, such as this one from Rheem, if you find yourself in this situation.

Replace the Drain Valve with a Ball Valve

It is substantially larger than a conventional drain valve to operate a ball valve. Replace your drain valve with a ball valve to not only clear your tank, but you’ll also prevent sediment from blocking it in the future as a result of the replacement. The following steps will show you how to replace your drain valve with a ball valve:

  • Purchase a 3/4″ abrasive ball valve as well as two 3″ dielectric nipples. (The nipples have been covered with acrylic to keep them from rusting). Each nipple will be attached to one of the ball valve’s two halves. Make use of teflon tape on the threads of the nipples that screw into the ball valve
  • And Keep in mind that the ball valve’s handle should be turned away from the tank when it is opened. Teflon tape should be applied to the second side of one of the nipples (just three of the four threads on each of the two nipples will be lined with teflon tape). Check to make sure that ALL of the faucets in the home are closed. When this happens, your water heater will generate a vacuum, which will prevent the water from “pouring out.” Place a bucket and a few towels beneath the drain valve to catch the water. Loosen the drain valve by turning it with an adjustable wrench. Remove the drain valve one turn at a time. Keep in mind that some water will be dripping from your tank. Even if your tank is completely blocked, you will very certainly have some water escaping from it. If the problem is caused by a defective drain valve, you will almost likely have water on your hands. Insert the new ball valve as soon as possible. This shouldn’t take more than a few seconds. Connect a garden hose to your tank and drain the contents
  • You should either replace the ball valve with a conventional drain valve or remove the handle for the sake of safety once your tank has been drained completely. It is possible that the handle will be accidentally opened, resulting in the draining of your tank. This has the potential to cause water damage and/or significant burns.

Due to the fact that ball valves are bigger than drain valves, they are capable of draining the most obstinate obstructions.

Use These Tips to Drain a Water Heater Properly

Disconnect the piping and the power supply. Move your water heater outside with a hand truck; To drain the water from the top of the tank, carefully turn your water heater on its side.

Before You Begin

Before you begin, make sure you understand where the main water shutdown valve is situated in your home. While you won’t necessarily need it during this procedure, it’s always a good idea to be familiar with this valve whenever you’re dealing with any type of plumbing fixtures in your house in case something goes wrong and you need to shut off all water coming through your pipes.

Safety Considerations

When doing this procedure, you will be working with water that can be quite hot. It is possible that you will need to switch off your hot water heater many hours before you begin in order to allow the water in the tank to calm down before you begin. If you are unable to do so, use heavy-duty rubber work gloves to protect your hands from any splashes and safety glasses to protect your eyes from any hot water droplets that may fall over them.

Perform a Quick Flush

Using a garden hose connected to the drain valve, attempt to clean the water heater tank a little bit while the water pressure is still on before shutting off the water supply. In order to accomplish this, first open the drain valve for a few seconds before closing it again. The pressure will blast away any silt that has become lodged in the valve, allowing the tank to empty more quickly. If a significant amount of sediment is expelled, you may need to repeat the process several times. Make certain that you’ve connected your garden hose to an outdoor place or into a bucket in order to collect the water and sediment that will be emitted from the faucet.

Turn Off the Water Heater

Turn off the gas to your water heater, or turn off the electricity if you have an electric water heater. Remove water by shutting off the valve on the cold-water pipe above the water heater or the main water supply valve to the home, whichever is most convenient. Test the hot water faucets around the home by turning them on and checking for water to ensure that the pressure has been released. Water may flood out at first, but if the water has been cut off properly, it should rapidly decrease to a trickle and then stop.

It is important to leave a hot water faucet open in the sink closest to your hot water heater in order to relieve pressure in the entire system. Kevin Norris’s The Spruce is a novel about a young man who grows up in the woods.

Open the Drain Valve

Open the drain valve while holding your garden hose in one hand. Normally, you may complete this task by hand, but you may need to employ your flat-head screwdriver in this instance. Once the valve is opened, water will begin to rush out of the drain, so make sure your hose is either connected to the outside or to a bucket to catch the water. You should switch off the drain valve as soon as the bucket is full so that you may empty it. Repeat the operation as many times as necessary to completely empty the tank.

Flush the Tank With Water

Once the tank has been completely drained, you may flush it with a few gallons at a time by turning on the water for a few seconds and then allowing it to drain out again until it is completely empty. When the outflow is clean, you’ll know that you’ve successfully eliminated the sediment and may proceed to the following phase in the process. Kevin Norris’s The Spruce is a novel about a young man who grows up in the woods.

Refill the Water Heater

Close the drain valve and remove the garden hose from the system. Make certain that all but one of your home’s hot water faucets are turned off (the one in the bathtub closest to the water heater is best). You may now re-start the water heater by turning the water back on. After that, keep an eye on the faucet you left open and, as soon as you notice that you are receiving nothing but water out of it, turn it off. Kevin Norris’s The Spruce is a novel about a young man who grows up in the woods.

Relight the Water Heater

Re-ignite the water heater’s pilot light, or if it’s an electric heater, re-energize the circuit breaker. You should be able to use hot water after an hour or so. Kevin Norris’s The Spruce is a novel about a young man who grows up in the woods.

Check the Drain Valve

Check for leaks at the spout of your water heater to see if the drain on the heater has completely closed. If the outlet does not completely close, you can stop the leak by placing a threaded hose cap over the hose thread of the outlet. Alternatively, you can replace the valve entirely.
