Recirculation and Combi System Service in Conway, AR
Many tankless units now include built-in recirculation pumps or buffer tanks to deliver faster hot water. These systems move more water through the exchanger and scale up sooner. We flush the recirculation loop, check pump operation and verify crossover or dedicated return line settings. Correct schedules can cut wasted energy while still giving you quick hot water.

Rinnai Tankless Water Heater Service in Conway
DGR Plumbing specializes in the maintenance of Rinnai tankless water heaters, a popular brand known for its efficiency. Our technicians in Conway are trained on Rinnai's specific diagnostic codes and service protocols. We handle common Rinnai issues such as error code 11 (ignition failure) or flow sensor malfunctions, so your unit operates at peak performance according to manufacturer specifications and local codes.
Error Code Diagnostics in Conway, AR
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 anything.
Isolation Valve Kit Installation in Conway, AR
Some tankless heaters were installed without service valves, which makes proper flushing impossible. 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.
Inlet Filter and Air Intake Cleaning in Conway
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. We pull and clean the screen and inspect the air intake filter, which can load up with dust and dryer lint. Clean filters keep the flow sensor reading correctly and the burner breathing properly.
Cost-Benefit Analysis for Maintenance in Conway
Investing in regular tankless water heater maintenance in Conway typically pays for itself through reduced energy bills and avoided repair costs. A well-maintained unit can save 10 to 20 percent on energy compared to a neglected one. We provide a clear breakdown of maintenance costs versus the potential savings from extended lifespan and improved efficiency, helping you make an smart decision for your Conway property.
