Tankless Descaling and Flushing in Greensboro
Hard water leaves calcium and magnesium scale inside the heat exchanger, limiting 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.
Recirculation Pump Repair in Greensboro
Many tankless systems use internal or external recirculation to deliver hot water more quickly. Pump failures, check valve problems or wrong schedule settings can cause long waits or lukewarm water. We test the pump, check valves and controls and set the schedule to match your daily routine. A properly tuned system saves both water and gas.
Gas Tankless Water Heater Repair in Greensboro
Gas tankless water heaters require precise gas pressure and proper ventilation for safe operation. Issues can range from gas valve failures to carbon monoxide sensor errors.

Minor repairs usually do not require a permit. If the repair involves major changes to the gas or water lines, or if the unit itself is being replaced, a permit from the Greensboro building department may be necessary. We handle all required permitting for you.
