  • s3 Take care not to damage the purge port valve caps when you remove them from the purge valves on each of the cold and hot water valves
  • The purge valves are distinguished by their little handles that mimic the letter “T.” In order to alleviate any pressure that has built up inside the valves, this technique must be performed in order to prevent excessive hot water from flying out and coming into touch with your skin. Due to the possibility of pressure build-up when removing the purge port valve covers, it is critical to ensure that the hot water valve is completely and correctly switched off for safety reasons. Using gentle pressure, gently tighten each cap to ensure the rubber washer sealing discs remain in place, which are required for your valves to operate correctly.
  • Fourth, connect your hosing lines to each of the three valves.

  • Opening the purge port valves by twisting them in the opposite direction of the cold and hot valves is a good way to start the process. 6 Instead of using chemical solutions to clean your tankless water heater, have 2.5 gallons (9.46 liters) of undiluted white vinegar on hand at all times.
  • In addition, because your tankless water heater is most likely the source of all of your drinking and bathing water, employing chemical cleaning solutions might have a negative impact on the quality of your water.
  • 7 Follow the manufacturer’s instructions for the flushing and draining of your tankless water heater to the letter to complete the operation.
  • 8After the flushing operation has been finished, close the purge port valves by twisting the “T”-shaped handles. Remove the hosing lines from each water valve by disconnecting and removing them. Tenth, attach the purge port valve covers to the purge valves

  • Make sure to tighten the caps completely and firmly without damaging the rubber sealing discs that are placed within the caps.
  • For specific information on how to properly re-start your tankless water heater, consult the manufacturer’s handbook.
  • If all that is required is for you to rotate and open the cold and hot water valves so that they are parallel to the position of the main valve that leads into the home, you have completed the operation.
  • Alternatively, slowly turn on the hot water tap in your sink to allow air to travel through the pipe.
  • Continue to run the water until it is running consistently and there is no air escaping from it
  • It is possible that this operation will take up to 2 or 3 minutes.

Create a new question

  • Question What should I do if there is a leak in the plumbing and steam is escaping while the hot water is being used? Your heat exchanger has developed a crack and will require replacement. You can purchase only that component or you can replace the entire tankless heater. Even though replacing a single component is less expensive (in terms of components), I chose to replace the entire unit because the water had seeped into the electronics, and who knows when that might cause another failure
  • Question Is it necessary to perform this procedure even if I have a water softener? Yes, since it’s critical to keep a tankless water heater in good working order. The heating components get very hot, causing calcium and other deposits to bake onto the heating units in a short period of time. Even if the water is from a clean municipal source, it should be filtered. A tankless heater’s life duration is significantly reduced if it is not properly maintained. They’re a highly delicate piece of machinery that requires constant attention and maintenance. Install a filter before the heater and clean it twice a year to ensure that it has a long service life. It is absolutely necessary. You’re more concerned with removing baked-on crap from the heating element than with clearing off dirt or debris. Question How long can I keep and reuse white vinegar after cleansing a Rinnai tankless water heater with it? Can I store and utilize the vinegar again? No, because the utilized vinegar contains dissolved particulates, it is no longer considered “virgin.” Always discard the old vinegar and replace it with new vinegar before flushing the toilet.

4. What Supplies Do You Need to Clean the Water Heater?

We’ve covered safety; now it’s time to speak about the supplies you’ll need to flush the unit. These are the materials you’ll need: While you may purchase each component separately, a flush kit contains everything you need in one convenient package. Alternatively, you may use 4 gallons of undiluted white vinegar instead of the descaling solution included in the flushing package.

5. How to Descale a Tankless Water Heater

We’re presenting the simple methods for descaling a water heater since it’s one of the maintenance activities that many homeowners can complete with little or no help from a professional. The first step is to turn off the power that is feeding your water heater. Locate and close the gas isolation valve if one exists. Shut off the hot and cold water shut-off valves while you’re working on the unit to prevent water from entering the unit. If your machine is equipped with a pressure relief valve, carefully open it to relieve any built-up pressure.

  1. Next, put the submersible pump in the bucket you just made.
  2. You may either pour four gallons of vinegar into the bucket or use the descaler that came with the flush package to remove the scale.
  3. Allow at least an hour for the descaling solution of your choice to circulate through the hot water heater.
  4. Following completion of descaling, switch off the pump.

6. Final Steps for Tankless Water Heater Cleaning

Closing the cold water service port and opening the cold water shut-off valve are the next tasks you need to do. This step removes any vinegar that may have remained. Following that, you’ll close the valve and allow the water to drain completely. It is now necessary to shut the hot water port. Finally, if there is a cold water input filter, make sure to remove it as well as the hot water in-line filter before continuing. Flush both of them in the sink to ensure that any remaining sediment is removed.

Keep in mind that, while it might be a fun DIY project, you may feel more comfortable having a professional plumber complete the task.

8 Steps to Maintain your Tankless Water Heater

An electric tankless water heater is one of the most energy-efficient and cost-effective ways to provide hot water for your house. Because it delivers hot water on demand, a tankless water heater system takes up less space and consumes less energy than a standard tank-style water heater system. The installation of a tankless water heater is a significant investment in your house, and they may last for up to 20 years if they are properly maintained. Tankless water heaters, like any other item in your house, require regular maintenance to ensure that they continue to function properly.

Turn off the energy source

Whenever you are doing inspection or maintenance on your tankless water heater, the very first thing you must do is switch off the electricity to the unit. The majority of tankless water heaters are powered by gas or electricity, while others are powered by kerosene or even propane. The maintenance operation is made safer by turning off the main gas outlet or the main power source at the circuit breaker before beginning.

Close all the water valves

To prevent water from entering the tankless water heater, you must close the water valves on the water supply lines. This also prevents any warm water from escaping the cleaning system during the cleaning procedure itself. To turn off the water, there are normally three color-coded water valves to use. Cold water is controlled by a blue valve, hot water is controlled by a red valve, and the third valve regulates the flow of water between the main water supply and your residence. Before commencing the maintenance procedure, be sure that all three of these valves are closed.

Disengage the purge port valve caps

Purge valves are included into your tankless water heater to aid in the control of pressure buildup. Each has a little handle that is shaped like the letter “T” on the end. When you remove the purge port valve covers, be careful not to overdo it since this can cause pressure to build up in the purge valves. This also stops hot water from spouting out, which may cause you to burn yourself.

Attach hosing line to each valve

In some cases, hosing lines may have been included with your tankless water heater; in others, you may need to purchase them from a home improvement store. Alternatively, the hosing line can be used to connect the water heater to a flushing bucket or other similar device. It is possible that you may need to connect the hoses to a sump pump. This enables the hot and cold water valves to flush through and release water from the tankless water heater unit while the device is in use. It may be beneficial to refer to the handbook that came with your particular tankless water heater model for more detailed instructions.

Open the port valves

Twist the port valves until they are perpendicular to the water valves, then release the twisting force.

Add descaling solution or white vinegar to the unit

To clean your tankless water heater, you can use a normal descaling solution or roughly 2.5 gallons of pure white vinegar.

Many households prefer vinegar over other cleaning products since it is typically believed to be safer.

Flush and drain the tankless water heater

You may next clean and drain your water heater using the directions in your owner’s handbook to ensure that everything is in working order. The water heater should be flushed and allowed to drain to the bucket for approximately 45 minutes to ensure complete cleaning. After the flushing has been done, you may close the port valves and then disconnect the hosing line from the water valves to complete the process. After that, you may gently reseal the purge valves with the port caps that came with them.

Restart the tankless water heater

Having everything in place, you may flush and drain your water heater, following the directions in your owner’s handbook for advice. The water heater should be flushed and drained to the bucket for roughly 45 minutes to ensure complete cleaning. You may then turn off the water and disconnect the hosing line from the water valves when the flushing process is complete. By carefully replacing the port caps on the purge valves, you can ensure that they are properly sealed once again.

Directions for Flushing Tankless Water Heaters:

The connections under the tankless water heater may be accessed by removing the cover on top of the unit. Some tankless types may not have a cover fitted at the time of purchase.

Step 2: Verify your tankless water heater has a flushing kit installed

If the flushing valves on your tankless water heater are not there, check to see if they have been installed. Stop what you’re doing and call a qualified plumber to install them.

Step 3: turn off the gas supply

Turn off the gas feed to the tankless water heater at the main shutoff valve. It will be necessary to switch the gasoline supply such that it is “perpendicular” to the fuel line. It is not necessary to cut off the electricity to the electric thermostat.

Step 4: Turn off the water supply

Close the cold water supply valve, which is responsible for supplying water to the tankless water heater, to prevent it from being used. Cold water is prevented from entering the unit as a result of this. Close the hot water supply valve, which is responsible for delivering hot water from the tankless water heater to the rest of the home. Shot water is prevented from entering the home as a result of this. Use this opportunity to inspect your temperature and pressure relief valve (T P valve) to confirm that it is in proper operating order.

Step 5: Open the flushing valves and connect the hoses

Remove the caps from the flushing valves and set them aside. This is important in order to relieve any pressure that has built up inside the valves. Connect the hoses to the flushing valves and tighten the connections with channel lock pliers to ensure that they are secure. Check to see that the rubber washers are properly seated in the tube to ensure a tight seal and avoid leaks. The flushing valves should be opened by rotating them 90 degrees at right angles (or perpendicular) to the existing positions of the cold and hot valves, respectively.

Step 6: Setup the bucket and sump pump

Add descaling solution or white distilled vinegar to the 5-gallon bucket until it is completely filled. Lower the sump pump into the 5-gallon bucket filled with descaling solution or distilled vinegar, and then turn on the sump pump to start the cleaning process.

Using a descaling solution, allow the sump pump to run for 30 minutes; if using vinegar, allow the sump pump to run for 1-2 hours.

Remove the hoses and pour the cleaning solution container into a trash can.

Using clean water, rinse off any residual descaling solution that may have accumulated in the bucket. Until the water running through the system is clear, you’ll need to repeat this procedure several times. When you’re finished, switch off the sump pump and throw away any residual solution.

Step 8: Finishing up and closing the system

The hosing should be removed from the flushing valves. Replacing and tightening the purge port caps properly is essential. Take care not to damage the rubber seals that are contained within the caps. If you do, you must replace them as soon as possible.

Step 9: Check the sediment filter

The sediment filter is situated on the cold water input line that feeds into the tankless water heater system. Remove the sediment filter by unscrewing it and wiping it off with a damp cloth if necessary. When you’re finished, remove the filter and replace it.

Step 10: Open the water supply to the tankless water heater

Rotate the cold water supply and hot water supply valves so that they are in line (or parallel) with the pipes before opening each of the valves.

Scaling and Its Impact on Tankless Water Heaters

If you neglect to schedule regular maintenance on your tankless water heater, scaling will have a negative influence on its performance and might cause it to fail prematurely. Hard water is the source of this problem, and hard water is defined as water that has a high concentration of minerals. Calcium, magnesium, and, in rare situations, iron, are the most often encountered dangers in the environment. These are completely innocuous minerals to consume, yet they may cause serious damage to your plumbing system.

It is possible that scaling will have a detrimental influence on the heat exchanger component of your tankless water heater.

This component must be free of contaminants in order for water to be heated efficiently.

When Should You Schedule Tankless Water Heater Maintenance?

Annual maintenance is required for some tankless systems in order to ensure that the system continues to operate efficiently over its full lifecycle. Others, possibly in places where hard water is not a significant issue, may only require maintenance every few years or even less frequently. A skilled plumber can assist you in determining the amount of hard water in your property. It’s possible that you’ll be able to discover its presence by yourself.

You have hard water if you see a chalky white or yellow deposit around your faucets or drains. This puts your tankless water heater at risk of failure. As a matter of fact, the installation of a whole house water softener may completely eliminate the effects of hard water.

When to Replace a Tankless Water Heater

It is necessary to do yearly or semiannual maintenance on a tankless water heater, although this will not extend the life of the system. Even though a tankless system can endure for more than 20 years, you will eventually need to replace it. Fortunately, this is a rather inexpensive process. The failure of your tankless water heater might occur much sooner than this if you have neglected to do regular preventative maintenance. Make sure to get in touch with our staff so that we can assist you in avoiding premature replacement.
