Step-by-Step Instructions:

1. Preparation:

Turn off the water supply to the bathroom. Open the faucet to release any remaining water in the lines.

2. Removing the Old Plumbing:

Disconnect the supply lines from the faucet and the shut-off valves. Unscrew the nuts on the P-trap and remove it. Detach the drain assembly from the sink.

4. Installing the P-trap:

Slide the P-trap over the drain assembly and tighten the nuts on both ends. Ensure that the trap is positioned correctly to prevent clogs.

5. Connecting the Supply Lines:

Wrap a few layers of Teflon tape around the threads of the supply lines. Screw the lines into the shut-off valves and faucet, respectively.

6. Installing the Faucet:

Place the faucet in the sinkhole and secure it with the mounting hardware. Attach the supply lines to the faucet.

7. Testing for Leaks:

Turn on the water supply and check for any leaks. If you notice a leak, tighten the connections where necessary.

Tips for Success:

Use a flashlight to inspect for leaks in hard-to-reach areas.
Tighten all connections snugly, but avoid overtightening.
Clean up any excess putty or water spills.
If you're unsure about any step, don't hesitate to consult a professional plumber.
