Rinnai Tankless Water Heater Repair in South Hill, WA
Rinnai is a popular tankless brand, and its units can face challenges such as scaling from hard water or issues with their flame rod.

We ensure your Rinnai system continues to provide reliable, on-demand hot water, following manufacturer specifications.
Flow Sensor and Thermistor Repair in South Hill
Tankless heaters rely on flow sensors to start and thermistors to regulate temperature. A dirty inlet filter or failed sensor causes no hot water, fluctuating temperature or the unit turning off mid-shower. We clean filters, test sensor readings and replace faulty parts. Temperature becomes steady again once readings are correct.
Electric Tankless Water Heater Repair in South Hill, WA
Electric tankless units offer a compact solution but can encounter problems with heating elements or circuit breakers. FHN Plumbing offers professional electric tankless water heater repair in South Hill, WA, addressing electrical faults, ensuring proper wiring and replacing faulty elements to restore your hot water supply safely and efficiently.
Recirculation Pump Repair in South Hill
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.
Condensing Tankless Repair in South Hill, WA
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 verify proper drainage. PVC venting is also checked for slope and sagging.
Commercial Tankless Water Heater Repair in South Hill
Commercial tankless water heaters in South Hill face heavier usage and require robust repair solutions. Whether it is for a restaurant, hotel or office building, we understand the urgency of maintaining hot water availability. Our commercial tankless water heater repair services address larger capacity units, complex manifold systems and often more severe scaling issues. We focus on fast, efficient service to minimize disruption to your business operations.
Tankless Descaling and Flushing in South Hill
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.
Pilot Light and Ignition Repair in South Hill, WA
For gas-fired tankless water heaters, a faulty ignition system can completely stop hot water production. Our team in South Hill, WA diagnoses issues with igniters, flame sensors and gas valves. We confirm 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.
