Over time, a tankless water heater can accumulate minerals that can build up on and erode the walls inside your tank’s heating chamber. To properly maintain and clean your unit, you must flush and remove the mineral deposits every 12-18 months. Watch the video below by Matt Risinger to learn how you can easily do this yourself to ensure optimal performance and efficiency.
A quick online search found that there are at least three vendors in the Brookwood area that will provide this service. The fee for the service runs up to $150 for a vinegar flush. Matt recommends assembling your own kit with the following parts available through Amazon at these links.
In addition to the recommendations on the video, be sure to open the supply valve and flush water through the unit to get the vinegar all out before you remove the drain hose. Otherwise you will get a supply of vinegar into the plumbing, and that might be unpleasant if the first user is making tea or bathing.
