In this video

It's time to mount the new garbage disposal. Align the top of the disposal with the sink flange mounting assembly. Lift the disposal up and turn the lower mounting ring clockwise until all three tabs on the disposal lock into the ramps on the sink flange. You can start it by hand and then use the disposal wrench or a screwdriver to fully tighten it, ensuring a snug and secure fit. Make sure the disposal's drain outlet is oriented towards the drain pipe.

Goal: Mount new disposal to the sink

  • Align the disposal drain outlet with your plumbing before fully tightening the mounting ring to avoid having to loosen it again.

FAQs

Why does this project recommend replacing the garbage disposal entirely instead of trying to repair the leak?

Leaks from the bottom of a garbage disposal often indicate a cracked housing or a failure in the internal seals, especially with older units. These issues are typically not repairable, making replacement a more reliable and often more cost-effective long-term solution than attempting temporary fixes. This approach also prevents future leaks from other aging components.

What is the most critical safety step before starting this project, and why is it so important?

The most critical safety step is disconnecting power to the disposal at your home's circuit breaker. This prevents accidental electrocution, which can be extremely dangerous when working with plumbing and electrical components. Always double-check that the disposal is completely de-energized by trying to flip its switch after cutting power at the breaker.

Besides the listed tools, are there any other common household items or tools I might find useful for this garbage disposal replacement?

Yes, a flashlight will be very helpful for better visibility in the tight space under the sink. You might also need a utility knife or hacksaw if the new disposal requires slight adjustments to your drainpipe length, and a small bucket or towels to catch any residual water from the old unit.

The project is labeled 'beginner' and '3 hours.' Is this realistic for someone with no plumbing experience, and what's the most challenging part?

Yes, this is a realistic estimate for beginners, as the process is primarily a direct replacement. The most challenging aspects are typically working in the cramped space under the sink and ensuring the new mounting assembly is tightened correctly with enough plumber's putty to create a watertight seal. Taking your time and following instructions precisely will make it manageable.

Now that you got the electrical hooked up, flip it over and install it, keeping this close to your discharge or bathroom. And when you flip this clamp down, make sure that all three points are connected right here, there's three points. But before you tighten that down, it's a good idea to make sure that you don't need to adjust it here. Looks like it's right on the money. Let's go ahead and use the tool that came with the garbage disposal. Or a filling screwdriver.
