How to Remove a Garbage Disposal and Install a Standard Sink Drain · Step 3 of 10
In this video
Before removing the disposal unit, you must first disconnect all associated plumbing. Start by loosening the nuts on the main PVC drain pipe that connects to the side of the disposal. These are often hand-tight slip nuts, but the screws on the flange connecting the pipe to the disposal may require a screwdriver. Also, locate the flexible drain hose from the dishwasher, which is typically attached with a metal compression clamp. Use a screwdriver to loosen this clamp and pull the hose off the disposal's inlet port. It's wise to have a bucket underneath to catch any trapped water.
Goal: Detach Drain Lines
- Disconnect the drain pipe before detaching the disposal unit from the sink. The weight of the unit can strain and break the plastic pipe if it's the only thing supporting it.

FAQs
What is the absolute first thing I need to do to ensure safety before touching any plumbing or electrical connections under the sink?
Before doing anything, turn off the power to your garbage disposal at the breaker box. This is crucial to prevent electrical shock. Additionally, turn off the water supply to your sink and place a bucket under the work area to catch any residual water.
The project says 'beginner' and '4 hours.' Is that realistic for someone with limited plumbing experience?
Yes, this project is generally beginner-friendly if you follow the steps carefully. The 4-hour estimate is reasonable for someone tackling this for the first time, assuming you have all tools and materials ready. Experienced DIYers might finish faster, but it's always best to budget extra time for unexpected challenges.
What's the most common reason for leaks after installing a new sink drain, and how can I prevent it?
The most common cause of leaks is improper sealing around the new basket strainer or loose connections in the drain pipes. Ensure you apply a generous, even bead of plumber's putty around the rim of the basket strainer before seating it. Hand-tighten all slip-joint connections firmly, then give them a quarter to half turn with pliers, being careful not to overtighten and crack the plastic.
Why is plumber's putty so important for this project, and how should I use it effectively?
Plumber's putty is essential for creating a watertight seal between the new sink basket strainer and the sink opening, preventing leaks. Roll a rope of putty about 1/2 inch thick and press it firmly under the flange of the new strainer before inserting it into the sink drain hole. Excess putty will squeeze out and can be easily removed.
