Installing Bathroom Sink Drain Trap

Installing a Bathroom Sink Drain Trap

A drain trap is an essential component of any bathroom sink, as it prevents sewer gases from entering the home and creates a water seal to stop debris from clogging the drain. Installing a drain trap is a relatively simple task that can be completed in a few hours with the right tools and materials.

Materials You'll Need

New drain trap
Slip joint pliers
Adjustable wrench
Plumber's putty
Bucket
Rags

Steps to Install a Bathroom Sink Drain Trap

1. Remove the Old Drain Trap

Place a bucket under the sink to catch any water that may leak out. Use slip joint pliers to loosen the nuts that connect the old drain trap to the sink drain and tailpipe. Once the nuts are loose, carefully remove the old drain trap.

2. Clean the Drain Hole and Tailpipe

Use a rag to clean any debris or old plumber's putty from the drain hole and tailpipe. This will ensure a good seal for the new drain trap.

3. Apply Plumber's Putty

Roll out a small piece of plumber's putty and shape it into a ring. Place the ring of putty around the base of the new drain trap.

4. Install the New Drain Trap

Insert the new drain trap into the drain hole and align it with the tailpipe. Hand-tighten the nuts that connect the drain trap to the sink drain and tailpipe.

5. Tighten the Nuts

Use an adjustable wrench to tighten the nuts further. Be careful not to overtighten, as this can crack the drain trap or damage the sink.

6. Test the Trap

Run water into the sink and check for any leaks around the drain trap. If there are any leaks, tighten the nuts further or reapply plumber's putty.

7. Clean Up

Wipe away any excess water or plumber's putty from the sink and surrounding area. Your new drain trap is now installed and ready to use.
