How To Install Trap Under Bathroom Sink

A trap is a U-shaped pipe that is installed under a sink or other plumbing fixture. The trap holds water, which creates a seal that prevents sewer gases from entering the home. Traps also help to prevent clogs by catching debris before it can enter the drain. Installing a trap is a relatively simple task that can be completed in a few minutes.

Materials You Will Need

Trap
Trap adapter
Slip joint pliers
Wrench
Plumber's putty

Instructions

Turn off the water supply to the sink. Open the faucet to release any remaining water.
Place the trap adapter on the drainpipe coming from the sink. Tighten the adapter with the slip joint pliers.
Apply a bead of plumber's putty to the rim of the trap. This will help to create a watertight seal.
Place the trap on the adapter. Tighten the trap with the wrench.
Turn on the water supply and check for leaks. If you see any leaks, tighten the trap or adapter as needed.

Tips

Use a trap that is the correct size for your sink. A trap that is too small will not be able to hold enough water to create a seal, and a trap that is too large may not fit under the sink.
Make sure that the trap is installed level. A trap that is not level may not drain properly.
Check the trap regularly for clogs. If the trap becomes clogged, it will need to be cleaned or replaced.

Conclusion

Installing a trap under a bathroom sink is a relatively simple task that can be completed in a few minutes. By following the instructions above, you can ensure that your trap is installed correctly and is functioning properly.
