Recirculation Pump Repair in Severn
Many tankless systems use internal or external recirculation to deliver hot water faster. 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 routine. A properly tuned system saves both water and gas.
Gas Tankless Water Heater Repair in Severn
Gas tankless water heaters require correct gas pressure and proper ventilation for safe operation. Issues can range from gas valve malfunctions to carbon monoxide sensor errors. Our certified technicians in Severn perform thorough diagnostics on gas lines, igniters and exhaust systems, so your unit is both functional and safe.
Flow Sensor and Thermistor Repair in Severn
Tankless heaters use 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.
No Hot Water Tankless Repair in Severn
When your tankless unit fails to produce hot water, it is often due to issues with the ignition, gas supply or a clogged heat exchanger.

Most municipal water across Maryland runs moderately hard, so scale slowly builds inside water heaters, faucet aerators and shower valves over the years. Tankless heaters scale up when water is hard, so expert repair and regular descaling are what keep these high-efficiency units running for their full lifespan.

Frequently Asked Questions About Tankless Water Heater Repair in Severn
The cost of tankless water heater repair in Severn varies widely depending on the issue, ranging from $150 for minor fixes like sensor replacement to $600 or more for complex repairs involving heat exchanger descaling or major component replacements. We provide a detailed estimate after diagnosing the specific problem.
Fluctuating temperatures can come from low flow rates, a dirty inlet filter, a failing flow sensor or scale on the heat exchanger. Crossed hot and cold lines at a fixture can cause it too.
Codes point to specific faults such as ignition failure, flame loss, overheating or scale buildup. Each brand uses its own code list, and we use manufacturer guides to interpret them.
Minor tankless water heater repairs, such as replacing a sensor or igniter, typically do not require a permit in Severn. Major component replacements, changes to the gas or water lines, or replacing the entire unit may require a plumbing permit to confirm code compliance.
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.
With regular descaling, tankless heaters often last 15 to 20 years. Without maintenance in hard water, problems can start within a few years.
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.
Regular professional maintenance, including descaling and checking all connections, is the best prevention. Installing a whole-home water softener can also significantly reduce mineral buildup in areas with very hard water.
