Recirculation Pump Repair in Greenville
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.

Tankless Water Heater Error Code Diagnostics in Greenville, RI
Modern tankless water heaters display error codes to flag specific problems, from flow rate issues to combustion errors. Our experts in Greenville, RI are trained to interpret these codes accurately, using specialized diagnostic tools to pinpoint the exact component failure.

Pilot Light & Ignition Repair in Greenville, RI
For gas-fired tankless water heaters, a malfunctioning ignition system can completely stop hot water production. Our team in Greenville, RI diagnoses issues with igniters, flame sensors and gas valves. We ensure proper gas pressure and ventilation are maintained for safe and efficient operation. Timely repair of these components prevents dangerous gas problems and restores your unit's ability to heat water on demand.
Condensing Tankless Repair in Greenville, RI
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.
Tankless Descaling and Flushing in Greenville
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.
Tankless Water Heater Descaling Service in Greenville
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, reducing efficiency and eventually causing breakdowns. Private wells serve many rural homes, and owners around Greenville benefit from testing for acidity, iron and other typical concerns. Our descaling service in Greenville involves flushing the unit with a specialized cleaning solution to dissolve these mineral deposits. This preventative maintenance and repair step is key for extending the lifespan of your tankless heater and keeping it at peak performance.

Gas Tankless Water Heater Repair in Greenville
Gas tankless water heaters require precise gas pressure and proper ventilation for safe operation. Issues can range from gas valve malfunctions to carbon monoxide sensor errors.
