What is a garbage disposal install?
A garbage disposal install mounts the unit to your sink drain. The plumber connects its outlet to the trap and links the dishwasher drain hose to its inlet. The unit also needs power, from a switched outlet or a hardwired circuit. Plumbers handle the plumbing side. If there’s no outlet under the sink, you need an electrician too.
Which size disposal should I pick?
| Motor | Best for | Typical unit price |
|---|---|---|
| 1/3 to 1/2 HP | Light use, small households | $90 – $180 |
| 3/4 HP | Most families | $180 – $320 |
| 1 HP and up | Heavy cooking, quieter operation | $300 – $450+ |
Bigger isn’t always better on a small sink cabinet. Measure the space under your sink before you buy. Leave room for a filter or trash pull-out.
What costs extra?
These add-ons raise the price of a disposal job:
- No outlet under the sink. Needs an electrician for a new switched outlet.
- First disposal on this sink. The drain may need a new tailpiece and trap arm.
- Dishwasher knockout. On new units, the plug inside the dishwasher inlet must be knocked out. Forgetting it floods the dishwasher.
- Old, corroded drain parts. Often replaced while everything is apart.
When should I replace instead of repair?
Replace the unit if the body leaks, since the seal can’t be fixed. Replace it if it trips the breaker again and again, or if it’s more than 10 years old and struggling. Repair it if it’s jammed, leaking at a hose clamp, or just needs a reset. If the sink backed up after a big meal, start with our guide to sink and disposal clogs after Thanksgiving.

Common questions
Can I have a garbage disposal on a septic system?
Often yes, but a disposal adds food solids to the tank, so plan on pumping it more often. Many homes in the townships around Grand Rapids are on septic. The EPA advises septic owners to limit or avoid using a garbage disposal to keep fats and solids out of the drainfield. Ask your plumber about models sold as septic-friendly.
What horsepower disposal do I need?
A 1/2 HP unit suits light use, like rinsing plates. A 3/4 HP unit suits most families and handles daily cooking scraps. A 1 HP unit is quieter, grinds finer and jams less, which helps if you cook a lot. Bigger motors are also taller, so measure the space under your sink before you buy one.
Why does my disposal hum but not spin?
It’s usually jammed. Turn off the power at the switch first. Then put the hex key that came with the unit into the socket on the bottom and work it back and forth to free the grinding plate. Press the reset button and try again. If it still hums after a reset, the motor may be failing and it’s time to replace it.
