Tankless Descaling and Flushing in Sumter
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.
Ignition Failure Repair in Sumter, SC
If your tankless unit will not fire, the cause may be a dirty flame rod, a bad igniter, low gas pressure or a blocked intake. We test each component and measure gas pressure at the inlet. Undersized gas lines are a common hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights reliably.

Private wells are common outside town limits, and some South Carolina well water carries iron, low pH or sediment that can stain fixtures and wear down water heaters. Tankless heaters scale up when water is hard, so careful repair and regular descaling are what keep these high-efficiency units running for their full lifespan.
