Garbage disposal leakingAlkmaar, North Holland

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.

Why this is common in Alkmaar

Alkmaar's historic canal ring is built on wooden pile foundations in waterlogged soil, creating the same drainage and leak challenges as Amsterdam canal houses but on a smaller scale. Lead water supply pipes remain in a significant proportion of pre-1970 homes, and the hard North Holland groundwater causes heavy limescale buildup in boilers and tap fittings.
