10 Easy Steps on How to Flush Tankless Water Heater With Vinegar
Step 1: Turn off the Power
First, you will need to turn off the power to your tankless water heater. This is usually done by unplugging it or turning off the circuit breaker that supplies electricity to the unit. Be careful not to shock yourself while doing this!
Step 2: Drain the Tank
Next, you will need to drain the tank completely. To do this, attach a garden hose to the drain valve on your tank and run it out onto a flat area outside where all of the water can be safely collected and disposed of properly. Don’t forget to open the drain valve before you start running the hose!
Step 3: Fill Tank With Vinegar Solution
Once all of the water has been drained from your tank, it’s time to fill it with a vinegar solution. You can make this solution by combining 1 gallon of white vinegar with 1 gallon of hot water in a bucket or other container. Be careful not to overfill the tank with this solution.
Step 4: Turn on the Power
Now, you will need to turn the power back on to your tankless water heater. This is usually done by plugging it back in or turning on the circuit breaker that supplies electricity to the unit. You can also refer to your owner’s manual for more detailed instructions on how to do this.
Step 5: Run the Solution Through the Tank
Once the power is back on, run your vinegar solution through the tank for about 20 minutes. Doing this will help remove any sediment and deposits that have built inside it over time. If you need to, you can also add additional vinegar solution during this time.
Step 6: Drain Tank Again
After running the vinegar solution through your tank for 20 minutes, drain it again using your garden hose like you did before. Remember to open the drain valve this time, too. It will help if you have someone to help you with this step.
Step 7: Refill Tank With Water
Once all of the vinegar solutions has been drained out, refill the tank with clean water. Now you will need to let it run for another 20 minutes in order to make sure that any remaining vinegar residue is flushed out of the system. You can also add additional water during this time if you need to.
Step 8: Drain Tank Again
When the 20-minute cycle is done, drain your tank one last time using your garden hose. This will ensure that no leftover vinegar remains inside the tank and can possibly contaminate your drinking water. Additionally, this will help keep your tank clean and free of any buildup.
Step 9: Turn the Power Off
You will need to turn off the power again by unplugging it or turning off the circuit breaker that supplies electricity to the unit. It is important to ensure the power is off before you start cleaning or maintenance on your tank. Because tankless water heaters use electricity to run, it is important to make sure that the power source is turned off before attempting to work on the unit.
Step 10: Fill the Tank With Water and Turn Power Back On
Finally, you will need to fill the tank with fresh water and turn the power back on. This is usually done by plugging it back in or turning on the circuit breaker that supplies electricity to the unit. Now your tankless water heater should be flushed and ready for use!
By following these steps, you can easily flush your tankless water heater with vinegar in a safe and cost-effective way. This process will help remove any sediment or deposits that have built up inside your tank over time, which can lead to blockages or reduced performance. Not only does this make sure that your tankless water heater runs efficiently, but it also ensures that the water coming out of it is clean, safe, and hot for you and your family to use.
