Disposal causes cabinet moisture and mold due to slow, intermittent leaks at plumbing joints.

Safety First: Turn OFF power at the breaker and avoid using the sink until leaks are corrected.

• Step 1 – Dry and inspect: Dry the area and then run water while observing all joints around the disposal, P-trap, and dishwasher connections.
• Step 2 – Tighten and reseal: Tighten slip nuts and replace any suspect gaskets. Use Teflon tape on threaded connections if applicable.
• Step 3 – Replace cracked fittings: Replace any PVC elbows or tees showing hairline cracks.
• Step 4 – Support piping: Add pipe hangers or straps to relieve stress on joints.
• Step 5 – Remediate moisture: Dry the cabinet thoroughly and treat or replace mold-affected materials.
