Recirculation Pump Repair in Bowling Green
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 daily routine. A properly tuned system saves both water and gas.

Pilot Light & Ignition Repair in Bowling Green, KY
For gas-fired tankless water heaters, a malfunctioning ignition system can completely stop hot water production. Our team in Bowling Green, KY diagnoses issues with igniters, flame sensors and gas valves. We confirm proper gas pressure and ventilation are maintained for safe and efficient operation. Timely repair of these components prevents hazardous gas problems and restores your unit's ability to heat water on demand.
Tankless Descaling and Flushing in Bowling Green
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.
Condensing Tankless Repair in Bowling Green, KY
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 confirm proper drainage. PVC venting is also checked for slope and sagging.

Electric tankless units offer a compact solution but can run into problems with heating elements or circuit breakers. BFK Plumbing offers expert electric tankless water heater repair in Bowling Green, KY, addressing electrical faults, confirming proper wiring and replacing faulty elements to restore your hot water supply safely and efficiently.
Tankless Water Heater Descaling Service in Bowling Green
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, reducing efficiency and eventually causing breakdowns. Water softeners are a common upgrade in Kentucky homes, protecting tank water heaters, faucets, and appliances from mineral buildup. Our descaling service in Bowling Green involves flushing the unit with a specialized cleaning solution to dissolve these mineral deposits. This preventative maintenance and repair step is crucial for extending the lifespan of your tankless heater and keeping it at peak performance.

Frequently Asked Questions About Tankless Water Heater Repair in Bowling Green
The cost of tankless water heater repair in Bowling Green, KY can range from $150 to $800 or more, depending on the issue. Simple fixes like sensor replacements might be at the lower end, while major component replacements like a heat exchanger could be higher. We provide a detailed estimate once we find the problem.
Minor tankless water heater repairs, such as replacing a sensor or igniter, usually do not require a permit in Bowling Green. Major component replacements, changes to the gas or water lines, or replacing the entire unit may require a plumbing permit to ensure code compliance.
Common signs include inconsistent hot water, a sudden loss of hot water, strange noises like banging or popping, a rotten egg smell or error codes displayed on the unit. Any of these symptoms warrant a professional inspection.
This often comes from low gas pressure, a blocked intake or exhaust, a dirty flame rod or overheating from scale. We test each possibility to pinpoint the cause.
Error codes can be triggered by a variety of issues, such as low water flow, gas supply problems, ignition failures, exhaust blockages or faulty temperature sensors. Each code points to a specific system malfunction.
Many tankless heat exchangers carry long warranties, while other parts usually have shorter coverage. Warranties may require proof of maintenance, which we document.
In homes with hard water and no softener, once a year is a good rule. Homes with a softener may go longer, but annual inspection is still wise.
Minor repairs usually do not require a permit. If the repair involves significant changes to the gas or water lines, or if the unit itself is being replaced, a permit from the Bowling Green building department may be necessary. We handle all required permitting for you.
