Garbage disposal leaking? Dit is wie je moet bellen

A leaking garbage disposal can drip from the top flange, side connections, or the bottom of the unit. Top leaks usually indicate a failing putty seal between the disposal and the sink. Side leaks point to loose hose connections at the dishwasher inlet or drain pipe. Bottom leaks mean the internal seals have worn out and the unit likely needs replacement. Left unaddressed, the constant moisture promotes mold, warps the cabinet floor, and can damage electrical connections. A licensed plumber can diagnose the leak location, reseal or tighten connections, and replace the unit if internal seals have failed.
