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. Our licensed technicians in Lake Forest perform thorough diagnostics on gas lines, igniters and exhaust systems, so your unit is both functional and safe.
Flow Sensor and Thermistor Repair in Lake Forest
Tankless heaters use flow sensors to start and thermistors to regulate temperature.

Temperature becomes steady again once readings are accurate.

Tankless Water Heater Descaling Service in Lake Forest
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, cutting efficiency and eventually causing breakdowns.

We provide a detailed estimate after identifying the specific problem.
Yes, our technicians are trained and experienced in repairing all major tankless water heater brands, including Rinnai, Navien, Noritz, Rheem, Bosch, A.O. Smith and more. We carry a wide range of common parts for various models.
Error codes can be caused by a variety of issues, such as low water flow, gas supply problems, ignition failures, exhaust blockages or faulty temperature sensors. Each code points to a specific system malfunction.
Minor tankless water heater repairs, such as replacing a sensor or igniter, usually do not require a permit in Lake Forest. Major component replacements, changes to the gas or water lines, or replacing the entire unit may require a plumbing permit to confirm code compliance.
This often comes from low gas pressure, a blocked intake or exhaust, a dirty flame rod or overheating from scale. We test each possibility to pinpoint the cause.
Common causes of failure include mineral buildup from hard water, ignition problems, faulty flow sensors, clogged air filters, exhaust venting issues and electrical component failures. Regular maintenance, including descaling, can prevent most of these problems.
Typical signs include inconsistent hot water, a sudden loss of hot water, strange noises like banging or popping, a rotten egg smell or error codes displayed on the unit. Any of these symptoms call for a professional inspection.
While some basic troubleshooting, like checking the power supply or gas valve, can be done, most tankless water heater repairs require special tools and knowledge. Attempting DIY repairs on gas or electrical components can be dangerous and void your warranty. It is always best to call a licensed plumber.
