Tankless Descaling and Flushing in Anderson
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 a smart move for most homes on hard water.
Emergency Tankless Repair in Anderson
A tankless unit that leaks internally or shows a fault you cannot clear needs quick attention. We put first no-hot-water calls and arrive with common sensors, igniters and filters. If a major component like a heat exchanger has failed, we check warranty coverage and order the part. We can often restore partial operation in the meantime.
Condensing Tankless Repair in Anderson, IN
Condensing tankless heaters, such as many Navien models, extract extra heat from exhaust and produce condensate. Clogged condensate traps, failed neutralizers and blocked drains can shut the unit down. We clean the trap, replace the neutralizer media and confirm proper drainage. PVC venting is also inspected for slope and sagging.
