Garbage Disposal Installation Services in Los Angeles

Quick answer: Replacing a garbage disposal means disconnecting the old unit, mounting the new one, reconnecting the drain and dishwasher line and checking the electrical connection. A new installation where there was none also needs an outlet or switch under the sink. Boss Plumbing installs and replaces garbage disposals across Los Angeles, usually the same day.

Choosing the right disposal

Motor size: 1/2 horsepower handles light use; 3/4 to 1 horsepower grinds more finely and jams less in busy kitchens.
Continuous vs. batch feed: continuous-feed units run from a switch; batch-feed units only run with the cover in place.
Sound insulation and stainless grinding parts make a noticeable difference in noise and lifespan.

See our garbage disposal buying guide for more detail.

How the installation works

Check the sink and drain. We confirm the drain height works for the disposal and dishwasher, and that the trap is the right type.
Remove the old unit and clean the sink flange.
Mount and connect. New mounting assembly, drain connection, dishwasher knockout and electrical connection.
Test. We run water and the disposal, run a dishwasher drain cycle if there is one and check for leaks.

Disposals in Los Angeles

Garbage disposals are allowed in Los Angeles homes and send food scraps to the sewer, but they're not a trash can: grease, fibrous peels, coffee grounds and eggshells are still common causes of kitchen drain clogs in the older, narrower pipes found in many LA homes. Los Angeles also has curbside food-scrap collection in the green bin, which is a better place for most food waste. See garbage disposal do's and don'ts.

Garbage disposal installation questions, answered

How long does garbage disposal replacement take?

Usually about an hour or two for a direct replacement. A new installation that needs an outlet or switch takes longer.

How much does garbage disposal installation cost in Los Angeles?

It depends on the unit, whether it's a replacement or a new install, and the electrical and drain setup. We explain the price before we start.

Can you install a disposal I bought?

Yes. We install customer-supplied disposals and will check that the model fits your sink and plumbing.

Do I need an electrician to add a disposal?

If there's no outlet or switch under the sink, the circuit has to be added. We'll tell you what's needed when we look at the setup.

What size garbage disposal do I need?

For most households, 1/2 to 3/4 horsepower is enough. Larger families and frequent cooks benefit from 3/4 to 1 horsepower.

Is it worth repairing an old disposal instead?

Jams and tripped resets are easy fixes. A leaking body or a burned-out motor usually means replacement. We'll tell you which makes sense.

Can a disposal go on a septic system?

Some models are made for septic systems, but most Los Angeles homes are on city sewer, so this rarely applies.

Can I connect my dishwasher to the disposal?

Yes. Most dishwashers drain through the disposal. The knockout plug inside the disposal's inlet has to be removed first, which we do during the install.
