Replace Your Garbage Disposal: Easy Guide · Step 4 of 5
In this video
Under the sink, connect the new components. Attach the drain hose to the sink drain or garbage disposal fitting and secure it with the clamp, tightening it with a screwdriver. Next, connect the water supply line to the hot water shut-off valve. Once both are connected, slowly turn the water valve back on and check for any immediate leaks at the connection point.
Goal: Connect the new dishwasher's drain and water lines to the under-sink plumbing.
- Ensure the drain hose has a high loop (higher than the connection point) to prevent water from the sink from flowing back into the dishwasher.

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.
