Tankless Water Header Warranty Flush
Tankless Water Heater Warranty Flush

Most tankless water heater manufacturers requires an annual flush to keep their warranty active. A tankless water heater may accumulate mineral build-up, restricting the water flow inside your tank’s heat exchanger. To properly maintain and clean your tankless, it is required to flush at least once a year. The best way to protect your tankless water heater (and satisfy the warranty) is to install a water softener. See below for more information on water softeners.

Another effective option to satisfy the warranty on a tankless water heater is to install a water softener. Utah is known for hard water. A water softener not only prevents build up in your tankless water heater, but also in your household appliances and water lines. There is also a cost savings to installing a water softener over doing years of flushes.

Cade Hunter

Director of Engineering (Intermountain Health Care)

“Big Sky Plumbing is awesome. They show up to appointments and returns calls in a timely manner. Their prices are very reasonable. They are a very honest company. One thing that stood out to me was when they installed a water softener and reverse osmosis at our brand-new home, they noticed the builder did not properly install our tankless water heater. They repaired the connections without even charging me. It was incredible that they would fix someone else’s issue. You will be happy with Big Sky Plumbing!”
