BGV Plumbing offers professional electric tankless water heater repair in Franklin, TN, addressing electrical faults, confirming proper wiring and replacing faulty elements to restore your hot water supply safely and efficiently.
Tankless Descaling and Flushing in Franklin
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.

Ignition Failure Repair in Franklin, TN
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 common hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights reliably.
