Hidden AC Condensation Line Leak Repaired in Chino Hills

A two story home in Chino Hills had an AC condensation line hidden inside a wall near the water heater closet. It had been leaking long enough to rot the framing and stain the slab. We opened the wall at the exact source, removed the failed line, and installed a new PVC condensate run, properly routed and strapped, so the wall could be closed up and stay dry.

Problem: AC condensate line leaking inside a wall
Repair: New PVC condensate line, routed and strapped

What the homeowner was facing

Condensation lines fail quietly. There is no gush of water and no spike on the water bill, just a slow drip inside a wall every time the air conditioner runs. By the time this one was found, moisture had been working on the framing for a long time. The studs and bottom plate were dark with rot and the slab under the wall cavity was stained where water had pooled.

What we found

Behind the drywall, the old condensate line ran through the wall cavity beside the water heater's supply piping. The line had been leaking around its fittings, wetting the insulation and framing around it. The wood shows exactly what a slow leak does when nobody can see it: blackened studs, softened framing, and staining spread across the bottom plate.

The repair

We cut the failed section out and built a new condensate run in PVC, routed cleanly through the cavity with proper elbows and a secure strap to the wall. The new line drains the way a condensate line should, with a clear path and no sagging joints to collect water.

The result

The wall got a new, dry line instead of another decade of hidden dripping. Catching a condensate leak at the source keeps the repair small. The alternative is what the before photos show: framing damage that spreads year after year until the wall itself needs rebuilding.
