Sink leaks and drain problems we repair in Palatine
A leak under the kitchen sink can come from a dozen joints, and the drip usually lands far from where it starts. Our licensed plumbers in Palatine dry everything, run water in stages to find the source and rebuild the part that failed.
Leaking garbage disposal connection
Disposals leak at the sink flange, the dishwasher inlet or the discharge pipe. Some are resealed; a disposal leaking from its body has to be replaced.
Leak at the drain in the wall
Water behind the sink base often starts at the wall connection. We open what we need to reach it and replace the failed fitting.
Old S-trap or wrong parts
Sinks hooked up with corrugated tubing or an S-trap tend to leak and smell. A properly sized P-trap fixes both.
Leak right after a new dishwasher install
If the sink cabinet got wet right after the dishwasher was put in, the drain connection is the first place we look.
Drip from the trap or slip joint
The nuts on a plastic or chrome trap seal with thin washers that wear, shift or crack. We replace the washers or the whole trap so the joints seal again.
Leak only when water runs
We test the supply and the drain separately so we fix the right part, not the one that happens to be wet.
Musty smell under the sink
Odor can also come from a dry or unvented trap. We check whether it is a leak, a venting issue or both.
