Garbage Disposal Services in Phoenix, AZ

Garbage Disposal Repair for Phoenix Kitchens

When the disposal quits, the sink backs up, the dishwasher may stop draining, and dirty water sits in the basin. Desert Peak Plumbing repairs, replaces and installs garbage disposals in homes across Phoenix, Scottsdale, Tempe, Mesa and Chandler. We also work on the parts around the unit, including the sink flange, the trap, the dishwasher hose and the power supply.

A few safe checks can save you a visit. Switch the unit off at the wall and keep your fingers out of the grinding chamber. Find the small reset button on the base of the unit and press it once. Many models also take an Allen wrench in the center of the base, which lets you rock a stuck plate loose. If the motor hums and the plate still will not move, stop running it, because a stalled motor overheats quickly.

A unit that makes no sound at all often points to a tripped reset, a tripped breaker or a loose wire, and we check those before recommending anything else.

Signs Your Garbage Disposal Needs Repair or Replacement

Some problems clear in minutes, while others mean the unit is finished. These are the signs Phoenix-area homeowners call us about most often:

• A humming motor with a plate that will not turn.
• Water dripping from the bottom of the housing onto the cabinet floor.
• A leak where the unit meets the sink or at the dishwasher hose.
• A reset button that trips again every few days.
• A grinding or rattling noise after a spoon or bottle cap went down.
• A sour smell that returns soon after cleaning.

A drip from the base of the housing usually means the internal seals have failed, and once water reaches the motor a repair rarely makes sense. Standing water in a sink cabinet also swells particleboard and invites mold, so treat a slow drip as urgent even if the disposal still grinds.

Common Garbage Disposal Problems and How We Fix Them

This table matches the problems we see most with their usual causes and fixes. We confirm the cause on site before we quote.

If the clog sits past the trap, the disposal is only the messenger. Our drain cleaning service clears kitchen lines packed with grease and food scraps, and older lines with heavy buildup may need hydro jetting. When the same kitchen line backs up again and again, a sewer camera inspection shows what is happening further down.

Installing a New Garbage Disposal in Your Kitchen

Once a unit is worn out, replacement usually ends the cycle of repeat calls. A smaller motor suits a household that scrapes most food into the trash, and a larger one handles heavier daily use with less strain and noise. We remove the old disposal, scrape the old putty off the sink opening and seat the new flange on a clean surface. We mount the unit, connect the drain and dishwasher line, and adjust the pipe if the new outlet sits at a different height than the trap. Then we run water, check each joint for drips and confirm the cord or hardwired connection is secure.

If the shut-off valves under the sink are crusted or stiff, we point that out while we are there.

Hard Water, Citrus Peels and Disposal Care in Phoenix

Phoenix water is very hard, and that shows up under the sink. Calcium and scale collect on the grinding plate, the sink flange and the shut-off valves, and that crust gives jams something to grip. Winter brings another local habit in the form of backyard citrus. Grapefruit, orange and lemon rinds are thick and fibrous, and feeding a whole bag of them in at once is a common way to stall a motor. Owners who leave for the summer, as many seasonal residents in Scottsdale and Mesa do, sometimes return to a disposal that seized after months without water. Run water and switch the unit on for a few seconds before you load it after a long absence.

A few habits keep a disposal running longer:

• Run cold water before you start grinding and keep it running briefly once the noise stops.
• Feed citrus rinds and other scraps in small handfuls.
• Keep grease, cooking oil and bacon fat out of the drain.
• Put pasta, rice, potato peels and coffee grounds in the trash.
• Keep corn husks, celery strings and artichoke leaves out of the unit.

Some problems start further back in the system. If you notice low water pressure, a wet patch in the yard, or a water bill that keeps climbing, the cause may be the line that feeds your home. Phoenix soil shifts with the heat, and older pipes crack over time. Our Water Line Repair & Replacement page explains how we find the leak and what your options are.
