Whether you're replacing a broken unit, upgrading to a more powerful motor, or adding a disposal to your kitchen for the first time, installation isn't as simple as swapping out a part under the sink.

Below, we'll cover what's involved in a professional installation, how to choose the right unit, and the most common questions Denver homeowners ask before scheduling a service.
Why Professional Installation Matters
Mistakes in any of these areas can lead to:
Leaks under the sink from improperly sealed flanges or loose connections
Electrical hazards from incorrect wiring near water sources
Premature motor failure from units that are undersized for household use
Dishwasher drainage issues if the knockout plug isn't properly removed
Code violations, particularly with electrical connections in older Denver homes
Our plumbers are experienced with Denver's plumbing and electrical codes and ensure every installation is completed safely and correctly.
Choosing the Right Garbage Disposal
Not all garbage disposals are created equal, and choosing the right unit depends on your household's cooking habits and kitchen setup. Key factors to consider include:
Motor horsepower
Ranges from 1/3 HP for light use to 1 HP or more for heavy, frequent use households
Continuous feed vs. batch feed
Continuous feed units operate with a wall switch, while batch feed units activate via a stopper, offering added safety
Noise insulation
Higher-end models include sound-dampening features for quieter operation
Grinding chamber capacity
Larger chambers handle more food waste per cycle
Corrosion-resistant components
Stainless steel grinding components last longer than galvanized steel
Dishwasher connection compatibility
Confirming the unit has a proper knockout plug for dishwasher drainage

What's Involved in a Garbage Disposal Installation
A professional garbage disposal installation typically includes the following steps:
- Disconnecting and removing the old unit, including plumbing and electrical connections
- Inspecting the sink flange and mounting assembly for wear or damage
- Installing a new sink flange and mounting hardware, sealed to prevent leaks
- Connecting the drain line and dishwasher hose, ensuring the dishwasher knockout plug is removed if applicable
- Wiring the electrical connection, either hardwired or via a cord and plug, depending on your setup
- Securing the unit to the mounting assembly and testing for stability
- Testing for leaks and proper drainage under running water before completing the job
We also haul away your old unit and clean up the workspace, so there's no mess left behind.
New Installation vs. Replacement
Installing a garbage disposal for the first time and replacing an existing one involve some different considerations.
First-time installation often involves:
- Running new electrical wiring to the unit if none currently exists
- Installing a new switch, typically wall-mounted near the sink
- Cutting and fitting a new sink flange opening if the sink wasn't originally designed for a disposal
- Coordinating with dishwasher plumbing if one is present
Replacement installation often involves:
- Matching or upgrading to a new mounting assembly, since brands vary in flange design
- Confirming existing wiring meets code requirements for the new unit
- Reusing or replacing the drain trap depending on condition
- Addressing any corrosion or damage from the previous unit's leaks
Our plumbers assess your specific situation, whether it's a first-time install or a replacement, and handle the wiring, plumbing, and mounting accordingly.
How Long Does Garbage Disposal Installation Take?
Most straightforward replacements are completed within one to two hours. First-time installations that require new electrical wiring or sink modifications may take longer, typically two to four hours, depending on the scope of work. We provide a time estimate upfront after assessing your kitchen's setup.
Can I Install a Garbage Disposal Myself?
Some homeowners attempt DIY garbage disposal installation, but it carries meaningful risk without the right experience. Common DIY pitfalls include:
- Improper flange sealing, leading to leaks that damage cabinetry over time
- Incorrect electrical wiring, creating a safety hazard near water
- Forgetting to remove the dishwasher knockout plug, causing drainage backups
- Mismatched mounting hardware between the old and new unit
- Choosing an undersized unit that fails prematurely under regular use
A professionally installed disposal not only reduces these risks but also comes with a warranty on the workmanship, so if an issue arises, you have a licensed plumber to call rather than troubleshooting on your own.
Signs It's Time for a New Garbage Disposal Installation
Consider a new installation if you're experiencing:
- A disposal that hums, fails to spin, or has stopped working entirely
- Frequent jams or a unit that struggles with everyday food waste
- Persistent leaks from a housing crack rather than a repairable seal
- A desire to upgrade to a quieter, higher-capacity, or more efficient model
- Plans to remodel your kitchen and update all fixtures at once
