A homeowner in Michigan sent an email that had me shaking my head, and not for the first time. Listen:
“Our house is heated by a Utica Gas Boiler that was here when we purchased this house. Sitting next to the boiler is a Hoffman boiler-feed pump. The problem we have encountered is that we’ve had to have the pump replaced five times since 1981. We have hard water (with iron) but I am not sure if that is the problem.
