Materials Required

Before you begin, gather the following materials:

• P-trap kit (includes P-trap, slip nuts, and washers)
• Adjustable wrench
• Pipe dope or Teflon tape
• Plumber’s putty
• Bucket or drain pan
• Rags or paper towels

Safety Precautions

• Turn off the water supply to the sink.
• Wear safety glasses to protect your eyes from splashing water.
• Use gloves to prevent contact with harsh chemicals.

Step-by-Step Instructions

1. Disassemble the Existing Drain

• Place a bucket or drain pan under the sink to catch any excess water.
• Use an adjustable wrench to loosen and remove the slip nuts connecting the P-trap to the drainpipes.
• Remove the old P-trap and discard it.

2. Clean the Drainpipes

• Use a rag or brush to clean the inside of the drainpipes to remove any debris or residue.
• Apply a small amount of plumber’s putty around the base of the drainpipes to create a watertight seal.

3. Assemble the P-Trap

• Apply pipe dope or Teflon tape to the threads of the trap arm (the longer arm of the P-trap).
• Screw the trap arm into the drainpipe on one side of the sink.
• Repeat the process on the other side of the sink.

4. Install the Slip Nuts

• Apply pipe dope or Teflon tape to the threads of the slip nuts.
• Hand-tighten the slip nuts onto the trap arm.
• Use an adjustable wrench to further tighten the slip nuts, ensuring they are snug but not overtightened.

5. Connect the Tailpipe

• Insert the tailpipe (the shorter arm of the P-trap) into the drain hole of the sink.
• Apply a small amount of plumber’s putty around the base of the tailpipe to create a watertight seal.
• Secure the tailpipe with the slip nut and tighten it using an adjustable wrench.

6. Check for Leaks

• Turn on the water supply to the sink.
• Inspect all connections for any leaks.
• If you notice any leaks, tighten the slip nuts or apply additional plumber’s putty as needed.

7. Clean Up

• Wipe away any excess plumber’s putty or water from the sink and surrounding area.
• Dispose of the old P-trap and any other discarded materials properly.

Troubleshooting Tips

• If the P-trap is leaking, check the slip nuts for tightness and apply additional plumber’s putty as needed.
• If the water is draining slowly, the P-trap may be clogged. Remove the P-trap and clean out any debris.
• If you encounter any difficulties during the installation process, do not hesitate to consult a professional plumber.
