Garbage Disposal Leaking in Charleston SC

A leaking garbage disposal shows water at one of three general points, and identifying which one narrows the cause significantly before a technician even needs to look at it.

A leak from the top of the unit, around where it meets the sink, usually means the sink flange seal has degraded — the rubber gasket that seals the disposal to the underside of the sink basin. This is one of the more common disposal leaks and is a relatively straightforward repair.

A leak from the side of the unit, specifically where the dishwasher drain hose connects, usually means that hose clamp has loosened or the connection itself has degraded — worth checking if the leak started around the same time as a dishwasher installation or repair.

A leak from the bottom of the unit is the least favorable of the three, since it typically means the internal seals of the disposal itself have failed — this is generally not repairable and points toward replacement rather than a fix, particularly on an older unit.

A leak at the discharge pipe (where the disposal connects to your home's drain line) rather than the unit itself is often just a loose connection or a worn gasket at that joint, unrelated to the disposal's internal condition.

Our technicians run water through the system while checking each of these points directly, since a leak that's only present during active use (rather than a slow constant drip) can be easy to miss without testing it running.

The $89 service call fee covers this full inspection. Flange seals and hose clamps are inexpensive, commonly available repairs; if the leak is from the unit body itself, your technician will explain honestly why replacement is the more sensible option rather than attempting a repair that likely won't hold.
