Garbage Disposal Installation
A garbage disposal can make kitchen cleanup easier by grinding up small amounts of food waste before it goes down the drain. Whether you’re replacing a unit that’s stopped working or adding a disposal for the first time, R&L Plumbing can install and connect it properly.
We do garbage disposal installation across San Francisco and the East Bay as part of our broader kitchen plumbing services. If your existing disposal can be fixed, see our garbage disposal repair service.
| Kitchen situation | What we’d recommend |
|---|---|
| Light household use, standard sink | A standard continuous-feed unit, 1/2 to 3/4 horsepower |
| Heavy daily use, larger household | A higher horsepower or batch-feed unit |
| Replacing an old, noisy unit | A newer unit with better sound insulation |
| No disposal installed yet | New hookup, including outlet and switch check |
What's Involved in a Garbage Disposal Installation?
If you’re replacing an existing unit, the plumbing connections are usually already in place. We disconnect and remove the old disposal, fit the new one to the sink flange, reconnect the drain line and dishwasher hose if needed, and check for leaks and a secure fit.
A first-time installation takes more planning. We’ll check the plumbing setup and whether the sink area already has the outlet and switch the disposal needs. If electrical work is required, we’ll let you know before installation begins so work can be coordinated.
Choosing the Right Disposal for Your Kitchen
Garbage disposals come in different sizes, power levels, and feed types. The right choice depends on how often you use it, how much space you have under the sink, and which features matter to you.
Continuous-feed models run while the switch is on. Batch-feed models operate only when the stopper is in place, which some households prefer for added safety. We can help you choose a unit that fits your sink and how you use your kitchen.
What Does Garbage Disposal Installation Cost?
Cost depends on the unit and whether you’re replacing an existing disposal or adding one for the first time. A new installation may require additional plumbing or electrical work that isn’t needed for a straightforward replacement.
We’ll give you a clear estimate before work begins. If you’re also doing a dishwasher installation, we can try to schedule both during the same visit.
Frequently Asked Questions
How long does a garbage disposal installation take?
A straightforward replacement is usually a relatively quick job. A first-time installation can take longer if new plumbing or electrical connections are needed.
Do I need a new outlet or switch for a garbage disposal?
Possibly. If your kitchen has never had a disposal, we’ll check the existing setup and let you know whether electrical work is needed before installation.
Will any garbage disposal fit my sink?
Not necessarily. Most standard disposals fit common kitchen sink openings, but the unit also needs enough space underneath the sink and must work with the existing plumbing. We can help make sure the model you choose fits your setup.
What size disposal do I need?
The right size depends on how often you use the disposal and the needs of your household. We can help you compare options and choose a model that works for your kitchen.
