Tankless Descaling and Flushing in Lewiston
Hard water leaves calcium and magnesium scale inside the heat exchanger, restricting flow and causing overheating. Many units warn of this with scale codes, such as the LC code on Rinnai models. We connect a circulation pump to the service valves and run a descaling solution through the exchanger. Annual descaling is wise for most homes on hard water.
Emergency Tankless Repair in Lewiston
