I’m worried about hard water sediment plugging up our HW heater. Any ideas?
Atwood, the current manufacturer of the post 1968 Bowen style water heater recommends an annual blowout of the water heater. Their method involves attaching an air fitting to the city water inlet, applying clean 40-50 PSI air and blowing the water of the heater. They say the scavenging action of the air bubbles will clear the calcium buildup. If you already have a build-up of material, you can use a gallon or two of white vinegar to loosen the calcium deposits. Put it in, let it soak overnight, flush it out good. You may have to repeat, depending on how much is in there.
