Garbage disposal runs but water backs up into the sink and drains very slowly.

Safety first: Turn off the disposal and do not run it while the sink is full of standing water.

• Check the sink baffle: Remove the rubber splash guard/baffle and clean any food buildup that may be restricting flow.
• Inspect the discharge elbow: Disconnect the drain pipe from the disposal discharge outlet and check for clogs inside the elbow or outlet. Clear debris with a brush.
• Clean the P-trap: Place a bucket under the trap, remove it, and clear any obstructions. Reassemble and check for leaks.
• Avoid chemical drain cleaners: Use a mechanical snake or auger for deeper clogs rather than harsh chemicals that can damage seals.

If the disposal outlet and P-trap are clear but drainage is still slow, the clog may be further in the home’s plumbing and a plumber may be needed.
