Garbage Disposal Installation
First-Time Setups Done Right
Adding a garbage disposal to a kitchen that never had one? Our plumbers handle the mounting, drain changes, dishwasher connection and power planning, so your new disposal works smoothly from day one.
Garbage Disposal Installation for Kitchens Without One
Installing a disposal where none existed involves more than bolting a unit under the sink. The sink’s basket strainer is replaced with a disposal mounting flange, and the unit hangs from a mounting ring below. The disposal’s outlet sits lower than a standard strainer, so the drain piping often needs to be rearranged, and sometimes the wall drain connection must be lowered for the trap to work properly with enough slope to drain.
Power is the other major piece. A disposal needs electricity, usually from an outlet under the sink controlled by a wall switch, or hardwired by an electrician. Kitchens without that setup may need a new circuit or outlet, or an air switch on the countertop that controls the disposal without new wall wiring. If you have a dishwasher, its drain hose must connect to the disposal inlet. We plan all of these details together for a clean installation.

Will a Disposal Work With Your Kitchen's Drain Height?
A disposal adds several inches of height below the sink compared with a basket strainer, which pushes its outlet lower inside the cabinet. For the trap to work, the trap arm must still slope downward into the wall drain. In many kitchens built for disposals, the wall drain sits low enough. In others, especially where the drain stub enters the wall high, the disposal’s outlet ends up below the drain connection, which won’t drain properly.
When that happens, the wall drain connection may need to be lowered by opening the wall behind the cabinet and adjusting the fittings. Choosing a disposal model with a higher outlet can sometimes avoid the work. Double-bowl sinks add another consideration, since the second bowl’s drain must tie in with proper slope. We measure everything before installation, so the new disposal drains smoothly and doesn’t leave standing water in the trap arm.
Why Customers Choose Our Disposal Installations
We plan first-time disposal installations from the drain to the power source. Our licensed and insured plumbers measure the drain height, adjust piping and wall connections as needed and remove the dishwasher knockout before connecting the hose, a step that’s easy to miss. We coordinate electrical work with licensed electricians or install air switches where appropriate. Every installation is tested with running water and, wherever possible, a full dishwasher discharge test.

Benefits of Professional Disposal Installation
Professional installation ensures your new disposal drains properly without standing water or slow drainage in the trap. Secure mounting prevents vibration, leaks and loosening over time. Correct dishwasher connections stop backups into the sink and dishwasher. Safe, correctly planned electrical setup protects your household and meets local code requirements. And planning drain changes in advance avoids frustrating callbacks and makes cleanup after meals faster and easier for years to come.

Air Switch or Wall Switch for Your Disposal?
Every disposal needs a way to turn it on. If your kitchen doesn’t have a switch already, there are two common ways to control it.
A wall switch is the traditional option, usually mounted near the sink and wired to an outlet under the cabinet. If the wiring already exists from a previous disposal, it’s simple. If not, a licensed electrician needs to run new wiring through the wall, which can involve opening drywall or backsplash tile.
An air switch uses a button mounted on the countertop or sink deck, connected by a small air tube to a control box under the sink that plugs into an outlet. Pressing the button sends a puff of air that switches the disposal on and off safely, with no wall wiring needed.
How Our Garbage Disposal Installation Works
We look at your sink, drain height, cabinet space, dishwasher and power options to plan the right disposal and configuration.
We then outline the unit, any drain changes, electrical needs and price. When work begins, the old strainer comes out, the sink flange and mounting assembly are installed and the drain piping is reconfigured, lowering the wall connection if necessary. Electrical work is completed by a licensed electrician when required.
The disposal is hung, tied into the drain and dishwasher hose and powered through a switch or air switch. Cold water is run while the unit grinds, the dishwasher is cycled to confirm it empties freely and each joint is inspected for seepage. You’ll learn safe operation and simple care tips.

Garbage Disposal Installation Questions Answered
Can a disposal be added to any sink?
Most kitchen sinks can accept a disposal. Drain height, cabinet space and power availability determine what changes, if any, are needed first.
Do I need an electrician for a disposal?
If there’s no outlet or switch under the sink, yes. An air switch can avoid new wall wiring, but still requires a nearby outlet.
Why must the dishwasher knockout be removed?
New disposals have a plug blocking the dishwasher inlet. If it isn’t removed, the dishwasher can’t drain and may back up.
Can septic homes get a disposal?
Usually, yes, with a septic-designed model and moderate use. Extra solids may require pumping the septic tank somewhat more often than usual.
How long does disposal installation take?
A straightforward installation takes about one to two hours. Drain lowering or new electrical work can extend the total time required.
