Replace Your Garbage Disposal: Easy Guide · Step 2 of 5
In this video
Place a bucket directly underneath the P-trap to catch any water that will spill out. Using a pair of channel-lock pliers, loosen the two large slip nuts that connect the P-trap to the sink's tailpiece and the drainpipe in the wall. Once the nuts are loose, the P-trap can be removed. Next, use the same pliers to disconnect the hot and cold water supply lines from the shut-off valves. Be prepared for a small amount of water to drip from these lines as well.
Goal: Disconnect P-Trap and Supply Lines
- Keep a rag or paper towels handy to clean up any small spills immediately.

FAQs
How do I ensure the power is completely off before I start working on the electrical connections?
Always turn off the power at your home's main electrical panel or breaker box for the kitchen circuit. It's crucial to double-check it's off by trying to turn on the disposal switch or using a non-contact voltage tester on the wires before touching any electrical components.
Do I really need a special garbage disposal wrench, or can I use other tools for removal?
While a dedicated garbage disposal wrench makes loosening the mounting ring easier, a sturdy flathead screwdriver can often be used. Insert the screwdriver into one of the mounting lugs and tap it with a hammer to rotate the ring counter-clockwise. However, the specialized wrench provides better leverage and reduces the risk of slipping.
Is this project truly beginner-friendly, and is the 3-hour estimate accurate for someone with no experience?
Yes, this project is considered beginner-friendly as it involves straightforward disconnection and reconnection steps, requiring patience more than advanced skills. The 3-hour estimate is reasonable for a first-timer, but allowing for up to 4-5 hours is wise in case you encounter stubborn old connections or unexpected plumbing configurations.
What are the most common reasons for leaks after installing a new garbage disposal, and how can I prevent them?
Leaks commonly occur at the sink flange due to insufficient or poorly applied plumber's putty, or at the drainpipe connections if they aren't tightened correctly. Ensure you apply a generous, even bead of plumber's putty under the sink flange, and hand-tighten all plumbing connections before giving them a final snug turn with pliers, being careful not to overtighten and crack plastic pipes.
