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.

Recirculation Pump Repair in Prairie Village
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.
