Flow Sensor and Thermistor Repair in Parker
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 failed parts. Temperature becomes steady again once readings are accurate.

Our team is familiar with Navien's parts and troubleshooting protocols, ensuring a precise and effective repair that maintains your unit's high efficiency.
Tankless Descaling and Flushing in Parker
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.

We make sure your Rinnai system continues to provide reliable, on-demand hot water, following manufacturer specifications.
Recirculation Pump Repair in Parker
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 Parker, CO

Emergency Tankless Repair in Parker
A tankless unit that leaks internally or shows a fault you cannot clear needs prompt attention. We put first no-hot-water calls and arrive with common sensors, igniters and filters.
