With the waste lines set, it’s time to install the water supply lines, which deliver fresh water to your faucet.
1. Connect the Water Supply Hoses
- Use your adjustable wrench to attach the supply hoses to the corresponding valves under the sink. Ensure that you’re connecting the cold and hot water lines correctly (usually marked with blue for cold and red for hot).
- Hand-tightening is adequate, but give a slight additional twist with the wrench to avoid leaks.
2. Connect to the Faucet
If you haven’t installed the faucet yet, do so now:
- Follow the manufacturer’s instructions to connect the faucet to the supply lines.
- Ensure all connections are tight.
Final Steps and Checking for Leaks
Now that everything is connected, it’s important to ensure there are no leaks in your newly installed plumbing.
1. Turn On the Water Supply
Slowly turn the water supply back on by opening the shutoff valves. Make sure to:
– Start with the cold water line and then turn on the hot water line.
– Open the faucet to allow air to escape and water to flow freely.
2. Inspect for Leaks
As the water flows, inspect all the connections—particularly the P-trap and slip nuts. If you notice any leaks, tighten the connections but remember that overtightening can cause damage to the pipes.
3. Test the Drainage
Run water through the sink to ensure that everything is draining correctly without any clogs or backup. This troubleshooting step will confirm that your connections are indeed leak-free and functioning correctly.
Maintenance Tips for Your Kitchen Sink Pipes
Once you’ve successfully connected your kitchen sink pipes, a little maintenance goes a long way in ensuring longevity. Here are some helpful tips:
