Flushing Your Tankless Water Heater


If you have a tankless water heater system within your home, then you may want to invest in a yearly plumbing maintenance service called a water heater flush. Learn more about why this flush is important and how your plumbing professional will complete it.

Why Do You Need Flushing?

First and foremost, if you have purchased one of the more high-end tankless systems, then you likely have a warranty for the appliance. And, in some cases, your warranty will be voided if you do not invest in the recommended water heater flushing. You need to go by the manufacturer's suggestions to keep your warranty in good standing, and this means a maintenance appointment scheduled usually around once a year. However, your plumber may suggest one more often based on the quality of your water. Basically, if you have more mineral content in your water, you should schedule a flushing service more often. 

The flushing is completed to keep the heat exchanger in working order. This part of the unit is where your water is heated. When this happens, minerals like calcium accumulate within the water pipes. The flushing helps to remove these minerals so a clog does not form in the unit. The flushing also ensures that the water heater is as efficient as possible and not being overworked.

What Happens During the Flushing?

During the flushing service, your plumber will remove the front cover from the system and shut off the gas. If the unit is an electric one, then the plumber will flip the breaker switch to shut off power to the system. They'll also close the water supply shut off valve to keep water from flowing through the system. And, the plumber will locate the service valves for the device. These valves allow for direct access to the water supply pipes across the heat exchanger unit.

Next, a flushing device is attached to the upper valve and a mixture of water and vinegar is pumped through it. The mixture helps to dissolve the minerals. The fluid then drains out the lower service valve opening and it is collected in a bucket. Your plumber will continue flushing until the vinegar flush solution looks clear. At this time, they'll use plain water to remove any vinegar that remains in the system.

Lastly, the plumber will close the service valves and turn the water supply back on. They'll also turn the unit back on, and they may ask you to run some hot water to make sure the device is working as intended. You will receive a receipt of service at the end of the appointment that you should keep for your records.
