Tankless Water Heater Descaling Service in Aloha
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, cutting efficiency and eventually causing breakdowns. Soft water can be slightly corrosive, which may lead to pinhole leaks in copper pipe and greenish stains on fixtures. Our descaling service in Aloha involves flushing the unit with a specialized cleaning solution to dissolve these mineral deposits. This preventative maintenance and repair step is crucial for extending the lifespan of your tankless heater and keeping it at peak performance.

PVC venting is also inspected for slope and sagging.
