About Tankless Water Heater Water Leak Repair

Water leaking inside a tankless water heater cabinet is an emergency. Even a slow, steady drip will corrode electrical wire harnesses, short out expensive control boards, and rust the combustion chamber casing. In Evergreen Park, Illinois, our technicians use sensitive moisture detectors and pressure testing to find the exact source of the leak. We replace hardened EPDM O-rings, reseal water servo fittings, replace cracked drain plugs, and repair loose union connections to keep your unit completely dry and protected.

Tankless Water Heater Water Leak Repair Questions

Why is water dripping from the bottom of my tankless unit in Evergreen Park, Illinois?

Dripping usually indicates a failed EPDM O-ring, a leaking flow sensor, a cracked condensate trap, or a pinhole in the heat exchanger. Call (888) 905-6092.

Is it safe to run a tankless water heater while it is leaking?

No. Water can drip directly onto high-voltage electrical connections or the gas valve solenoid, creating fire and shock hazards. Shut it off.

How quickly can you fix a water leak on my tankless heater?

We carry comprehensive O-ring kits, brass fittings, and replacement valves to fix most leaks in under an hour. Call (888) 905-6092.

What Our Customers Say

Real reviews from property owners we've helped across Evergreen Park, Illinois.

Our Navien tankless unit threw an E003 error right before family arrived for the weekend. The technician showed up in 28 minutes, tested the gas line pressure with a digital manometer, cleaned a calcified flame rod, and had our hot water running perfectly. Honest, fast trade work.

We had a bad cold water sandwich effect in our upstairs master shower. Every time someone turned on a faucet downstairs, the shower went ice cold. TWH PRO's installed a compact buffer tank and recalibrated the bypass servo. Showers are finally completely steady.

Our restaurant's three-unit commercial Rinnai manifold locked out on a busy Friday dinner rush. TWH PRO's dispatched a master technician who isolated the cascade communication glitch and swapped a failed combustion blower in an hour. Saved our entire dinner service.
