Installing a new dishwasher involves much more than simply sliding the unit into a cabinet space. It requires connecting to your home’s water supply, ensuring the drain line is secure, and making a correct electrical connection.

Preparing for Dishwasher Setup
While we handle the heavy lifting, a few planning steps ensure your new unit fits perfectly and operates flawlessly:
Space Verification: Confirming the new dishwasher dimensions fit the existing opening, especially counter height and depth.
Power Access: Ensuring there is a dedicated electrical outlet or hardwired connection point available.
Water Valve Access: Knowing the location of the under-sink hot water shutoff valve, which is needed for connection.
Water Line and Drain Connections
The drain and supply lines are the most critical elements, as failure here can lead to water damage in your kitchen cabinets. We prioritize safety by only using durable, flexible, stainless steel braided supply lines. For the drain connection, we ensure the knockout plug is fully removed if connecting to the disposal. Most importantly, we install the drain hose with the proper high-loop or air gap configuration to prevent dirty drain water from backing up into the clean dishwasher.
