Garbage Disposal Installation Services in Phoenix, AZ
A properly installed garbage disposal provides years of convenient food waste management. If you are adding a unit to a new sink or replacing an old, broken one, professional installation ensures the unit is sealed correctly, wired safely, and connected to the drain line without future clogs or leaks.
Professional Disposal Installation
We install all types of disposals, from standard models to high-powered continuous feed units. Our installation service covers all necessary steps for a flawless setup:
- Sink Flange Sealing, ensuring a watertight seal at the drain opening to prevent leaks into the cabinet.
- Electrical Connection, safely wiring the disposal unit to the power source and wall switch.
- Dishwasher Drain, connecting the dishwasher drain line correctly, including removing the knockout plug if necessary.
- Drain Piping, customizing the disposal's drain pipe connection to the existing P-trap and wall drain to ensure smooth, clog-free flow.
Kitchen Plumbing We Service
The kitchen has more plumbing connections than any room in the house. Here’s what we work on most.
Kitchen Sinks and Faucets
Drips, clogs, sprayer issues, and full sink-and-faucet replacements during a counter swap.
Garbage Disposals
Repair, replacement, jam clearing, and disposal-to-air-switch installs. We'll tell you whether yours is worth saving.
Dishwasher Hookups and Leaks
New install, replacement, or chasing down a slow leak under the cabinet. We catch the leak source — not just the symptom.
Ice Maker and Fridge Water Lines
Saddle-valve failures and cracked supply lines are the #1 cause of kitchen flooding. We replace them with proper shut-offs.
Kitchen Drain Cleaning
Grease, food, and soap build up where the drain bends under the slab. We snake or jet depending on the line condition.
Kitchen Remodel Plumbing
New island, peninsula, or sink relocation. We handle the rough-in and final connections so your contractor can keep moving.
No matter your situation, our plumbers provide service you can rely on.

Garbage Disposal Repair
Humming, jammed, leaking, or just plain dead? Most disposals can be repaired faster and cheaper than replaced — we'll tell you straight which one your situation calls for.
Garbage Disposal Installation
Upgrading to a quieter unit or installing your first disposal? We'll size it right for your sink, your habits, and your drain line — and install it without surprises.
Garbage Disposal Replacement
When a repair isn't worth it, we'll pull the old unit, install the new one, and make sure the connections are tight before we leave. Same-day in most cases.
Kitchen Sink Installation
Drop-in, undermount, farmhouse, or a switch from double to single basin — we handle the plumbing side so your new sink lands level, sealed, and ready to use the same day.
Kitchen Faucet Installation
Touchless, pull-down, pot filler, or a straight swap — we mount it solid, hook up the supply lines properly, and pressure-test before we call it done.
Kitchen Faucet Repair
Drips, low pressure, loose base, or a sprayer that won't switch back — we diagnose the actual cause before replacing parts. Sometimes it's a $20 cartridge, not a $400 faucet.
Dishwasher Installation
New unit, replacement, or a built-in upgrade — we run the water line, drain, and air gap to code so the appliance warranty stays valid and you don't get a flood six months later.
Ice Maker Installation
Adding a fridge with an ice maker or routing a line to a standalone unit? We run a clean, code-compliant water line with a proper shutoff so you can service it without tearing into the wall.
Refrigerator Water Line Installation
Replacing the cheap saddle valve your builder used, or running a fresh line for a new fridge — we install rigid copper or proper PEX with a real shutoff. No slow leaks, no frozen lines.
Kitchen Remodel Plumbing
Moving the sink, adding an island, or gutting the whole space? We work alongside your contractor — or solo if you're the GC — to rough in supply, drain, and gas lines that pass inspection the first time.
No matter your situation, our plumbers provide service you can rely on.
Choosing the Right Disposal Unit
Disposals are rated by horsepower (HP) and feed type. We help you choose the ideal fit for your kitchen needs, whether you need a lighter duty unit (1/3 to 1/2 HP) for occasional use or a heavy-duty model (3/4 to 1 HP) for large families and tougher scraps. We also review the pros and cons of batch feed (safer, operates with a stopper) versus continuous feed (more common, operates with a switch).
Safe and Correct Installation Steps
Our plumbers take meticulous care during installation to prevent the most common post-install issues, like leaks or jams:
- Preparation: Turning off power, clearing the space, and dry-fitting the new unit.
- Secure Sealing: Applying a consistent, leak-proof seal around the sink flange and securing the mounting ring tightly.
- Knockout Removal: For dishwasher connections, carefully removing the plug without dropping plastic pieces into the unit.
- Final Check: Testing all drain connections under running water and confirming the unit turns on and processes food waste smoothly.
