Garbage Disposal Repair in San Diego County and the Temecula Valley

A garbage disposal grinds food scraps under your kitchen sink so they wash down the drain. Pipe Dream Plumbing Co. repairs and installs garbage disposals across San Diego County, the Temecula Valley and the Inland Empire, and tells you straight when a repair is not worth it.

A garbage disposal is the grinder under your kitchen sink that breaks food scraps into small pieces so they can wash down the drain. You need it looked at when it hums without turning, trips its reset button, leaks or will not run at all. We fix and replace disposals all over San Diego County, the Temecula Valley and the Inland Empire, with the price in writing before we start.

Many disposal problems are quick fixes. A jam can often be freed, a tripped reset button pressed, and a loose drain connection tightened. Others mean the unit is finished, and the most common of those is a leak from the body of the disposal itself, which no part fixes.

Before you call, our post on a garbage disposal that is not working walks through the safe checks you can do yourself. Always switch it off at the wall and never put your hand inside.

Flat, written price before work starts.

What are the signs your garbage disposal needs repair or replacement?

It hums but does not turn: Something is jammed between the grinding plate and the housing, or the motor is seizing. Turn it off right away so the motor does not overheat.
It does nothing at all: Check the reset button on the bottom of the unit and the breaker. If both are fine, the switch, the wiring or the motor has failed.
Water under the sink: A leak at the top usually means the sink flange seal. A leak at the side is often a hose connection. A leak from the bottom of the body means the unit is worn through.
The sink drains slowly or backs up: The clog is often past the disposal, in the trap or the kitchen drain line, especially if grease goes down the sink.
It keeps tripping the reset button: Repeated trips mean the motor is overheating, from jams, a worn motor or running it without enough water.
Grinding has gotten loud or slow: Worn grinding parts take longer and sound rougher. On an older unit, that usually points toward replacement.

How does a garbage disposal repair or replacement work, step by step?

1

Diagnose it

With the power off, we check for a jam, test the reset and the switch, and find exactly where any water is coming from.

2

Repair or recommend

If a jam, a reset or a connection is the problem, we fix it on the spot. If the unit is leaking from its body or the motor is failing, we recommend replacement and give you the price first.

3

Remove the old unit

We disconnect the drain, the dishwasher hose and the power, and take the old disposal off its mount.

4

Install the new one

We fit new mounting hardware and a fresh seal at the sink, connect the drain and the dishwasher hose, and connect the power cord or wiring.

5

Test everything

We run water, run the disposal, run the dishwasher drain, and check every connection under the sink for leaks.

Should you repair or replace a garbage disposal?

Repair when the problem is outside the grinding chamber: a jam, a tripped reset, a loose connection, a worn sink seal or a bad switch. Replace when the body is leaking, the motor is failing, or the unit is old enough that the next repair will not be the last. A disposal is a sealed appliance, so once water gets out through the housing, replacing it is the only fix.

What size disposal do you need?

Disposals are sold by motor size, measured in horsepower. A smaller motor handles light, everyday scraps. A larger one grinds faster and finer and jams less with tougher scraps, which helps in kitchens that cook a lot. Some are louder than others. We match the unit to how you use your kitchen and to the space under the sink.

Why does the kitchen drain clog behind the disposal?

Because a disposal makes food smaller, not gone. Grease, coffee grounds, eggshells, rice and fibrous scraps like celery still build up in the trap and the drain line. If the sink keeps backing up after the disposal is fixed, the line itself may need drain cleaning, and a kitchen line coated in grease may need hydro jetting.

What do you need to know about the dishwasher connection?

Most dishwashers drain through the disposal. A new disposal has a small plug inside its dishwasher inlet that has to be knocked out before the hose is connected, or the dishwasher cannot drain. The dishwasher hose also needs a high loop or an air gap so dirty sink water cannot flow back into the dishwasher. We check both on every install.

What affects the cost of a garbage disposal repair or installation?

These are the things that move the price:

Repair or replacement
Clearing a jam or resealing a connection is a short visit. A new unit adds the disposal itself.
Unit size
Larger motors cost more than smaller ones.
Power
A plug-in cord and an outlet under the sink is simpler than a unit that is wired in directly, or a kitchen with no switch for it.
First-time install
Adding a disposal where there has never been one can mean a new outlet, a switch and changes to the drain.
Drain condition
A clogged or corroded drain line behind the disposal is priced separately if it needs work.

Flat, written price before work starts.

What does our garbage disposal repair & installation service include?

Diagnosis of jammed, humming, leaking and dead disposals, clearing jams and drain clogs behind the disposal, replacement with a unit sized to your kitchen, dishwasher connections, new mounting hardware and drain connections, and checks on the kitchen drain line when it backs up.

Benefits of Our Garbage Disposal Repair & Installation Service

A straight answer on repair or replace
The drain checked, not just the disposal
Dishwasher connection done right
Sized to how you cook
Old unit hauled away
Experienced, insured plumbers

What maintenance keeps problems from coming back?

Run cold water before, during and for a few seconds after you use the disposal, so scraps carry all the way down the line.

Keep grease, oil, coffee grounds and fibrous scraps out of it. They are what clog the drain behind the unit.

If it jams, switch it off at the wall before you do anything. Never reach into the chamber.

Common Questions

What do homeowners ask about garbage disposal repair & installation?

Why does my garbage disposal hum but not work?

Something is jammed between the grinding plate and the housing, or the motor is seizing. Switch it off right away. Many units can be freed from underneath with the right tool; our troubleshooting guide shows how. If it hums again after it is freed, the motor is likely failing.

Can a leaking garbage disposal be fixed?

It depends where it leaks. A leak at the sink flange or a hose connection can be fixed. A leak from the body of the disposal cannot, because the housing is sealed, so the unit has to be replaced.

How long does a garbage disposal replacement take?

A straight swap of one unit for another is usually a short visit. A first-time install that needs a new outlet or switch, or drain changes, takes longer.

What should never go in a garbage disposal?

Grease and oil, coffee grounds, eggshells, bones, fruit pits, and stringy scraps like celery and corn husks. Rice and pasta swell and can clog the drain. When in doubt, use the trash.

Will a new disposal work with my dishwasher?

Yes. We connect the dishwasher drain hose, knock out the inlet plug on the new unit, and make sure the hose has a high loop or air gap so sink water cannot drain back into the dishwasher.

Do I need a plumber or an electrician for a disposal?

For a replacement on an existing outlet or connection, a plumber handles the whole job. If your kitchen has no outlet or switch for a disposal, that electrical work is added to the job and priced before we start.
