Recirculation Pump Repair in Eagle
Many tankless systems use internal or external recirculation to deliver hot water more quickly. 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 daily routine. A properly tuned system saves both water and gas.

Ignition Failure Repair in Eagle, ID
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. Undersized gas lines are a frequent hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights every time.
Condensing Tankless Repair in Eagle, ID
Condensing tankless heaters, such as many Navien models, extract extra heat from exhaust and produce condensate. Clogged condensate traps, failed neutralizers and blocked drains can shut the unit down. We clean the trap, replace the neutralizer media and verify proper drainage. PVC venting is also checked for slope and sagging.

Commercial tankless water heaters in Eagle face heavier usage and require robust repair solutions. Whether it is for a restaurant, hotel or office building, we understand the urgency of maintaining hot water availability. Our commercial tankless water heater repair services address larger capacity units, complex manifold systems and often more serious scaling issues. We prioritize fast, efficient service to minimize disruption to your business operations.
Tankless Descaling and Flushing in Eagle
Hard water leaves calcium and magnesium scale inside the heat exchanger, restricting flow and causing overheating. Many units warn of this with scale codes, such as the LC code on Rinnai models. We connect a circulation pump to the service valves and run a descaling solution through the exchanger. Annual descaling is wise for most homes on hard water.
