Introduction to Dishwasher Installation

The dishwasher is one of the most relied-upon appliances in any modern kitchen. It saves time, reduces water usage compared to hand washing, and ensures your dishes are sanitized after every cycle. But for it to perform correctly, it must be installed with care.


Adept Installation provides expert dishwasher installation services in St. Louis and surrounding counties. With over 40 years of combined experience, we know that the difference between a reliable dishwasher and one that leaks or rattles comes down to installation. We don’t just slide the unit into place — we prepare the space, adjust cabinetry if needed, secure connections, and run full test cycles to confirm everything works as intended.


Whether you’re replacing an existing dishwasher or adding one to a kitchen that never had one, Adept Installation handles the details that other installers often overlook.

Why Professional Dishwasher Installation Matters

Dishwashers combine electricity and water in a confined space, making safety and precision critical. Small errors during installation can cause big problems:



  • Leaks – An improperly tightened connection or missing drainage loop can lead to water damage inside your cabinetry.
  • Noise and vibration – A dishwasher that isn’t leveled or secured may rattle loudly during cycles.
  • Poor drainage – Without a proper high loop or air gap, dirty water can backflow into the dishwasher.
  • Tipping hazards – If not anchored, the unit can tip forward when the racks are extended.


Professional installation eliminates these risks. At Adept Installation, we follow manufacturer guidelines and local best practices, making sure your dishwasher is safe, secure, and ready for years of quiet service.

Our Process Step by Step

1. Pre-installation review

We start by reviewing the new dishwasher model and comparing dimensions to your existing cutout. If flooring or cabinetry creates clearance issues, we plan the necessary modifications.


2. Protecting your home

Before work begins, we cover floors and counters to guard against scratches and damage.


3. Removing the old unit

If replacing an existing dishwasher, we disconnect and carefully remove the old appliance. Water lines are capped to prevent drips, and electrical connections are secured.


4. Preparing the space

We clean the cavity, check cabinet stability, and confirm water, drain, and electrical access. When necessary, we trim cabinets or cut access points to create a proper fit.


5. Water line and shut off valve installation

We replace old, unreliable valves and install new supply lines when required. This step prevents future leaks and gives you a safe, accessible shut off.


6. Drain connection setup

We secure the drain hose with a high loop or install an air gap as required by manufacturer instructions and local code.


7. Installing the new dishwasher

The unit is carefully slid into place, leveled front to back and side to side, and anchored with mounting brackets.


8. Testing and final check

We run a full wash cycle to confirm leak-free operation, smooth rack movement, and quiet performance. After cleanup, we review the installation with you and provide care tips.

Adding a Dishwasher to a Kitchen for the First Time

Not every kitchen is built with a dishwasher in mind, especially in older homes. Adept Installation specializes in adding dishwashers where none previously existed. This process often includes:



  • Removing a base cabinet to create space.
  • Installing a new water supply line and shut off valve.
  • Adding a dedicated drain connection.
  • Running electrical supply safely to the new location.
  • Finishing cabinet edges and trim for a seamless look.


The result is a fully integrated dishwasher that looks original to your kitchen design.
