Step-by-Step Installation Guide

- Place a bucket under the sink to catch any water that may leak out.
- Use an adjustable wrench to loosen the slip nuts that connect the P-trap to the sink drain and the drainpipe.
- Carefully remove the old P-trap.
2. Clean the Drainpipe
- Use a cloth to wipe away any debris or old plumber’s putty from the drainpipe.
- If the drainpipe is corroded or damaged, it may need to be replaced.
3. Apply Plumber’s Putty
- Roll out a small piece of plumber’s putty into a snake shape.
- Wrap the putty around the base of the new P-trap’s inlet and outlet connections.
- Smooth out the putty to create a watertight seal.
4. Install the P-Trap
- Align the P-trap with the drainpipe and sink drain.
- Hand-tighten the slip nuts onto the connections.
- Use an adjustable wrench to further tighten the slip nuts, but avoid overtightening.
5. Install the Washers
- Place a washer on each slip nut.
- Tighten the slip nuts again to compress the washers and create a leak-proof seal.
6. Connect the Trap Arm

- Use the same slip nut and washer technique to secure the connection.
7. Test for Leaks
- Turn on the water supply to the sink.
- Check for any leaks around the P-trap connections.
- If you find any leaks, tighten the slip nuts further or add more plumber’s putty.
Tips for a Successful Installation
