Recirculation Pump Repair in Pasadena
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.

Emergency Tankless Repair in Pasadena
A tankless unit that leaks internally or shows a fault you cannot clear needs quick attention. We put first no-hot-water calls and arrive with common sensors, igniters and filters. If a major component like a heat exchanger has failed, we check warranty coverage and order the part. We can often restore partial operation in the meantime.
Noritz Tankless Water Heater Repair in Pasadena, CA
Noritz tankless heaters are known for their sturdy design, but can sometimes face issues such as flow sensor malfunctions or venting problems. We provide dedicated repair services for Noritz units in Pasadena, CA, ensuring proper combustion, water flow and exhaust, which are crucial for safe and efficient operation.
Ignition Failure Repair in Pasadena, CA
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.
Flow Sensor and Thermistor Repair in Pasadena
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 correct.

Municipal water across much of Southern California is hard, leaving white scale on faucets, showerheads, and inside water heater tanks. Tankless heaters scale up when water is hard, so expert repair and regular descaling are what keep these efficient units running for their full lifespan.
