Running plumbing for a dishwasher involves connecting the dishwasher to the water supply and drain lines. Here's a step-by-step guide to help you with the process:
Tools and materials you'll need:
- Dishwasher installation kit (usually includes a water supply line, a drain hose, and necessary fittings)
- Screwdriver
- Adjustable wrench
- Pliers
- Pipe thread sealant (optional but recommended)
Step-by-step guide:
Choose a location: Select a suitable location for the dishwasher near your kitchen sink. Make sure there's enough space to accommodate the dishwasher and its connections.
Shut off the water supply: Locate the hot water shut-off valve under your sink and turn it off. This valve is usually connected to the water supply line leading to the faucet.
Prepare the water supply line: If your dishwasher installation kit includes a water supply line, it should have a fitting that connects to the shut-off valve under your sink. Use pliers or an adjustable wrench to remove the existing hose from the valve. Attach the new water supply line from the dishwasher kit to the valve, and tighten it securely.
Install the water inlet valve: The other end of the water supply line will connect to the water inlet valve on the dishwasher. Locate the water inlet valve at the back of the dishwasher and attach the supply line to it, making sure it's tightly connected.
Connect the drain hose: Find the dishwasher's drain outlet at the back of the unit. Connect one end of the drain hose from the dishwasher installation kit to this outlet. The other end of the hose should be connected to the drain under your sink. If there's a high-loop or air gap provided in your dishwasher kit, install it to prevent backflow of water.
Check for leaks: Once all connections are made, turn on the water supply valve under the sink. Check for any leaks at the water supply line connection and the dishwasher's water inlet valve. If you notice any leaks, tighten the connections or apply pipe thread sealant to the threaded areas.
Test the dishwasher: Before pushing the dishwasher into its final position, plug it into an electrical outlet and run a test cycle to ensure everything is working correctly. Keep an eye on the water supply and drain connections during this test to verify there are no leaks.
Secure the dishwasher: Once everything is in working order and there are no leaks, slide the dishwasher into its designated space under the countertop. Secure it in place with screws to the cabinets on either side to prevent movement during use.
That's it! By following these steps, you should have successfully run plumbing for your dishwasher. If you're uncertain about any part of the process or encounter difficulties, consider seeking help from a professional plumber or appliance installer.
