Garbage Disposal Repair & Installation

A garbage disposal that hums but won’t spin, leaks from underneath, or has simply gone silent is one of the more common kitchen plumbing calls we get — and often one of the faster ones to resolve, once we know exactly what’s actually wrong with it.

Signs Your Garbage Disposal Needs Attention

Look out for:

• Humming or buzzing when switched on, but the blades don’t actually spin
• Water leaking from underneath the unit, whether from the top, bottom, or discharge pipe
• Unusual grinding, rattling, or metallic noises during operation
• Frequent jams, or a reset button that keeps tripping repeatedly
• No response at all when the switch is flipped — no sound, no movement

Our Process

When a disposal hums but doesn’t spin, we start with the simplest and most common causes: a jam from fibrous food waste, a utensil, or another foreign object caught between the impeller and the grind chamber, or a tripped internal reset button (a small red button on the underside of most units) that shuts the unit down as a safety measure when it overheats or jams. Clearing a jam and resetting the unit resolves a large share of these calls without needing to replace anything.

If the unit is silent altogether, we check whether it’s receiving power at all — sometimes it’s as simple as a tripped breaker or a loose electrical connection — before assuming the motor itself has failed. When the motor has genuinely burned out, or when a leak is coming from inside the unit body rather than a fitting or connection, that’s when we talk about replacement rather than repair, since a failed motor or a cracked housing isn’t something that can be fixed in place.

For leaks specifically, we check each potential source separately: the flange connection at the sink drain, the discharge pipe connecting to your home’s drain line, the dishwasher inlet connection if your disposal handles dishwasher drainage, and seals within the unit itself. Identifying exactly where the water is coming from determines whether the fix is a simple gasket or connection tightening, or whether it points to a failing unit that needs replacing.

When replacement is the right call — whether due to age, a failed motor, or an internal leak — we size the new unit to your household’s actual cooking and disposal habits rather than defaulting to the cheapest or most powerful option by default, and we connect it properly to your existing plumbing and electrical, including the dishwasher drain connection where applicable. For kitchens that have never had a disposal at all, we assess what’s needed to add one — checking sink drain compatibility and electrical access — and handle the full installation.

What to Expect During Your Appointment

Most disposal calls are resolved quickly. We’ll start by checking power to the unit and looking for an obvious jam, since these two causes account for a large share of “disposal isn’t working” calls. If it’s a jam, we’ll clear it, reset the unit, and test it running with water to confirm it’s operating normally before we consider the visit complete.

If the issue turns out to be a failed motor, a cracked housing, or an internal leak that means the unit needs replacing, we’ll show you what we found — for instance, a leak visibly coming from the unit body itself rather than a loose connection — and talk through replacement options sized to your household’s needs. Installation of a new unit, when needed, typically takes under an hour for a standard swap, including reconnecting the dishwasher drain line if applicable and testing the full setup afterward.

For new installations in a kitchen that’s never had a disposal, we’ll assess the sink drain configuration and available electrical before the appointment where possible, so we can arrive with the right parts, though in some cases additional electrical work discovered on-site may need a brief follow-up.

Local Considerations for Phoenix-Area Disposals

Disposal seals and internal components can be affected by the same hard-water mineral buildup that affects other plumbing fixtures across the Valley, though typically to a lesser degree than water heaters or fixtures that see constant water flow. What we see more often locally is simply that disposals reach the upper end of their eight-to-twelve-year expected lifespan and start showing motor wear around the same time other fixtures in an aging home are due for attention — which is why a disposal replacement sometimes comes up as part of a broader kitchen plumbing refresh rather than as an isolated failure.

Households across Phoenix, Scottsdale, and the wider Valley with heavier disposal use — larger families, frequent cooking with fibrous vegetable scraps — tend to see jams and wear happen somewhat sooner than lighter-use households, which is worth factoring in when deciding whether to repair an aging unit or move on to a new one.

If you’re unsure whether your disposal habits are contributing to repeat jams, we’re glad to point out what we’re seeing during the repair — certain fibrous scraps and starchy foods are common culprits, and a small change in habits sometimes prevents the next service call entirely. We’d rather leave you with that kind of practical insight than just clear the jam and move on to the next appointment.

It’s also worth knowing that running cold water while the disposal operates, rather than hot, helps solidify grease and fats so they get ground up and flushed through rather than coating the inside of the unit and the drain line beyond it — a small, simple habit that can meaningfully reduce how often a disposal jams or a connected drain line needs professional cleaning down the road.

Pricing Transparency

Most disposal jam-clearing and reset calls are quick, affordable fixes, and we’ll let you know on arrival if that’s what we’re dealing with. If the diagnosis points to a failed motor, internal leak, or other issue that means the unit needs replacing rather than repairing, we’ll explain why and provide a clear estimate for a new unit and installation before doing that work — we won’t replace a disposal that a simple jam-clearing would have fixed.

For new installations, whether replacing an old unit or adding one where none existed, our estimate covers the unit, any necessary connection work, and removal of the old unit if applicable.
