Local Area Note: Serving communities across San Francisco and the Peninsula, Heise's Plumbing is familiar with regional Bay Area water conditions, municipal codes, and the unique architecture of local residential properties.
Garbage disposals usually jam when hard debris, fibrous foods (like potato peels or celery), or metal objects get wedged between the impeller blades and the outer shredder ring. They can often be cleared safely using an Allen wrench from underneath.
Look for moisture pooling inside the cabinet, warped wood, musty smells, or mold growth. Water lines and drain slip-joints can slowly leak under pressure, causing major structural rot before they are noticed.
The main water shutoff valve is typically located where the main water line enters the home, in the garage, or near the street curb. Turning this gate or ball valve fully clockwise will stop all water flow to the house.
