Installing a dishwasher with a garbage disposal may seem like a daunting task, but with the right tools and guidance, it can be a straightforward process. Proper installation ensures your dishwasher and garbage disposal work efficiently, helping to simplify your cleaning routine
This guide on how to install a dishwasher with a garbage disposal will walk you through the essential steps, from preparing the space and making the necessary connections to testing the system for optimal performance. Whether you’re replacing an old unit or setting up a new one, following these instructions will help you achieve a hassle-free setup.
Why Install a Dishwasher With a Garbage Disposal?
Before we dive into the installation process, let’s first understand why you would want to install a dishwasher with a garbage disposal. A garbage disposal is an essential kitchen appliance that helps break down food waste and prevent clogged drains. By connecting your dishwasher to the garbage disposal, any food particles left on dishes can be easily disposed of, preventing them from building up in your pipes.
Additionally, installing a dishwasher with a garbage disposal allows for efficient use of space under your sink. Instead of having two separate units taking up valuable cabinet space, combining them into one unit maximizes storage potential.
What You Will Need
To successfully install a dishwasher with a garbage disposal, you will need the following tools and materials:
Dishwasher
Make sure to have the correct dishwasher size and type for your space. You can choose from portable, built-in or drawer dishwashers, depending on your needs.
Garbage Disposal
Select a garbage disposal that is compatible with the type of sink you have (stainless steel or porcelain) and meets any local plumbing codes.
Basic Tools
- Screwdriver
- Adjustable Wrench
- Pipe Cutter or Hacksaw
- Pliers
- Measuring Tape
- Level
Other Materials
- The dishwasher installation kit Includes a drain hose, clamp, and other necessary hardware.
- Power Cord for the Dishwasher (if Not Included)
7 Simple Step-by-step Guidelines on How to Install a Dishwasher With a Garbage Disposal
Step 1: Prepare the Space
Start by ensuring the area under your sink is clear and ready for installation. Remove any items stored beneath the sink to give yourself enough working room. Next, turn off the power to the dishwasher connection at the circuit breaker and shut off the water supply to avoid any accidents during installation.
Measure the space where the dishwasher will be installed to confirm it fits properly. If you’re replacing an old dishwasher, disconnect and remove it carefully, making sure to inspect the water lines and electrical connections for any damage that needs to be addressed before proceeding. Also, verify that the garbage disposal is operational before starting the installation.
Step 2: Connect the Water Supply
To connect the water supply, locate the dishwasher inlet valve, which is typically found at the bottom of the dishwasher. Attach one end of the water supply line to this inlet valve and tighten it securely using an adjustable wrench. Ensure the connection is snug, but avoid overtightening, as this could damage the valve.
Next, connect the other end of the water supply line to the shut-off valve, which should already be installed on your kitchen’s water line. Before securing the connection, apply plumbing tape to the threads of the shut-off valve to ensure a watertight seal. Tighten the fitting using a wrench, ensuring it is firmly attached.
Step 3: Install the Drain Hose
Take the dishwasher drain hose and connect one end to the disposal inlet, which is located on top of the garbage disposal unit. Secure it in place with a clamp. The other end of the drain hose should be connected to the dishwasher’s drain outlet. Ensure this connection is also secure with a clamp.
It is essential to ensure the drain hose has a high loop, which prevents dirty water from your sink from running back into the dishwasher. Attach the loop to one of the mounting clips that come with your installation kit and secure it in place using a screw.
Step 4: Connect the Electrical Wiring
If your dishwasher did not come with a power cord, you will need to install one. First, turn off the power at the circuit breaker before connecting any wires. Then, carefully follow the manufacturer’s instructions to connect three wires (black for hot, white for neutral, and green for ground) to their corresponding terminals on the dishwasher.
Next, plug the other end of the power cord into an electrical outlet. If your dishwasher comes with a power cord, simply plug it into the designated outlet.
Step 5: Attach the Dishwasher to the Cabinet
To secure the dishwasher in place, use mounting brackets or screws provided in your installation kit. Depending on the type of dishwasher you have, follow the manufacturer’s instructions on how to attach it properly to the cabinet.
You can also use a level to ensure the dishwasher is perfectly aligned and adjust the feet accordingly for stability.
Step 6: Connect the Dishwasher to the Garbage Disposal
Locate the outlet on your disposal unit, which should have a knockout plug that needs to be removed. Use pliers or a screwdriver to remove it, then insert the dishwasher drain pipe into this opening and secure it with a clamp.
The garbage disposal should also have a dishwasher tailpiece, which is used to connect the dishwasher drain pipe. Secure this connection using pliers or a wrench.
Step 7: Turn on the Power and Water
Before turning on the power, double-check all connections and make sure they are secure. Once you’ve confirmed everything is properly connected, turn on the water supply and check for any leaks. If there are no leaks, turn on the power at the circuit breaker.
Following these simple steps on how to install a dishwasher with a garbage disposal, you can successfully install a dishwasher with a garbage disposal in your kitchen. Remember to follow the manufacturer’s instructions and consult a professional if you encounter any issues during installation. Enjoy your new efficient and space-saving kitchen appliances!
