Water Under the Sink That Wouldn't Quit - Two Culprits Found

Water pooling under the sink is one of those problems that's easy to ignore - until the cabinet floor starts warping or you open the door and get hit with a musty smell. Most people assume it's the drain pipe or a loose fitting. Sometimes that's right. But sometimes the real source isn't the sink at all.

That's exactly what we found here. The drain piping had worn connections that were letting water seep out even when no one was using the tap. That alone would've been enough to deal with. But there was a second problem hiding right alongside it - a leaking A/C condensation line that had been quietly dripping into the cabinet. Two separate sources. One soggy mess.

The old piping told the whole story once we pulled it out. You can see the buildup and deterioration at the connection points - that kind of wear doesn't happen overnight, and it doesn't fix itself. We replaced the under-sink drain assembly with clean, properly seated fittings and tackled the condensation line at the same time so everything leaving that cabinet is tight and accounted for.

That's the thing about leak detection - the visible water almost never tells you the full story. Tracing it back to every actual source is what separates a real fix from a temporary patch. We don't close a job until we've confirmed there's nothing else contributing to the problem.

If you've got water showing up somewhere it shouldn't and you can't quite figure out why, that's worth looking into sooner rather than later. The longer a slow leak goes, the more it quietly damages everything around it.
