No tank, still leaks
Tankless Water Heater Leak Repair in Wheaton, IL
Tankless units skip the big steel tank but keep their own leak points: condensate drains that clog, isolation and service valves that weep, heat exchanger seals that age, and the same supply fittings every heater has. Diagnosis works differently here — you read error codes, check condensate flow, and inspect seals rather than hunting tank rust. We trace tankless leaks to their source, fix them properly, and set you up with the descaling habit that keeps heat exchangers alive. Certified Professional, Licensed & Insured Team.

About this service
Tankless leak repair with a descaling plan
Most tankless leaks we see come down to maintenance gaps. Hard water scales the heat exchanger, raising temperatures and stressing seals; condensate lines grow slime and back water up into the cabinet; isolation valves sit untouched for years and then weep when finally operated. We diagnose with the unit's own diagnostics plus a hands-on inspection, replace failed seals and valves, and clear blocked condensate paths.
Serving Wheaton, IL 60187, we don't just fix the leak and leave: every tankless visit ends with a maintenance plan matched to your water — descaling intervals, condensate line checks, and the warning signs to watch between visits. That routine is what keeps a tankless unit from leaking again. Call (833) 713-2101.
How it works
What your visit looks like
Shutoff and safety first
We close the water and gas or power to the unit and confirm it is safe to open and service.
Tankless-specific diagnosis
We check the unit's diagnostics, condensate drainage, isolation valves, seals, and connections to find the true leak point.
The plan, in plain language
We explain what failed — seal, valve, condensate blockage, or fitting — and what the repair involves.
Repair and reseal
Failed seals and valves are replaced, condensate paths cleared, and the unit is run through a full operational check.
Your prevention handoff
We set your descaling schedule and show you the condensate and valve checks that keep tankless leaks from returning.
FAQ
Questions we hear about tankless units
Where should I look for a tankless leak?
The usual suspects: condensate drain lines, isolation and service valves, heat exchanger seals, and supply connections. Unlike tank models, there is no big steel tank to rust through — so most tankless leaks trace back to seals, valves, or drainage rather than the unit's core.
Why is water constantly coming out of my tankless unit's condensate line?
A steady trickle is normal for condensing units, but constant heavy flow or water where it shouldn't be points to a blocked or misrouted condensate line, or an internal issue. We check the drain path first — it is the simplest cause and the most overlooked.
What maintenance prevents tankless leaks?
Regular descaling matched to your water hardness, keeping the condensate line clear, and exercising the isolation valves during service. That routine protects the heat exchanger seals and keeps small issues from becoming cabinet-flooding ones.
