Inlet Filter and Air Intake Cleaning in Nitro
Every tankless unit has an inlet water screen that catches grit and scale flakes. Those screens can clog with sand and debris, especially after municipal line work.

Noritz tankless water heaters are sturdy systems, but they still require annual tune-ups to maintain their performance through every season. Our maintenance includes checking the unit's exhaust system, confirming proper combustion air intake and verifying the integrity of the heat exchanger.

Error Code Diagnostics in Nitro, WV
Codes like Rinnai LC, Navien E003 or Noritz 90 tell us a lot about what is going wrong. We read the code history, test flame rods, flow sensors and igniters and check gas pressure at the inlet. Many codes trace back to scale or a dirty filter and clear after maintenance. When a part has failed we explain the repair and the cost before doing any work.

Isolation Valve Kit Installation in Nitro, WV
Some tankless heaters were installed without service valves, which makes proper flushing very difficult. We install a set of isolation valves with purge ports on the hot and cold lines so future maintenance takes minutes. The kit also lets you shut off water to the heater without closing the main. It is a one-time upgrade that pays for itself in simpler service.
