J bend sink traps, also known as P-traps, are essential plumbing components that prevent sewer gases from entering your home. They create a water seal that blocks the passage of these gases, ensuring a clean and odor-free indoor environment.
Materials Required
Before embarking on the installation process, gather the following materials:
- J bend sink trap
- Slip joint washers
- Basin wrench
- Adjustable wrench
- Plumber’s putty
- Tape measure
- Hacksaw (optional)
1. Remove the Old Trap
- Use a basin wrench to loosen the nuts connecting the old trap to the sink and drainpipe.
- Carefully remove the trap and discard any old washers.
2. Clean the Drainpipe and Sink Flange
- Use a rag to clean any debris or residue from the drainpipe opening.
- Apply plumber’s putty around the base of the sink flange, where the trap will connect.
3. Install the Slip Joint Washers
- Place a slip joint washer over the drainpipe opening.
- Position the washer inside the end of the J bend trap.
- Repeat the process for the other end of the trap.
4. Connect the Trap to the Drainpipe
- Align the J bend trap with the drainpipe opening.
- Hand-tighten the nuts on both ends of the trap.
- Use an adjustable wrench to further tighten the nuts, ensuring a snug fit.
5. Connect the Trap to the Sink
- Place the other end of the J bend trap over the sink flange.

- If leaks occur, tighten the nuts further or add additional plumber’s putty as needed.
7. Trim the Excess Pipe (Optional)
- If the trap is too long, use a hacksaw to trim the excess pipe from the vertical arm of the trap.
- Ensure that the cut is clean and perpendicular to the pipe.
Troubleshooting Tips
- If you encounter a leak at the connection between the trap and the drainpipe, the slip joint washers may not be properly seated. Remove the trap and reassemble it, ensuring that the washers are positioned correctly.
- If the trap is not draining properly, the vertical arm may be clogged. Remove the trap and clear any debris or obstructions.
- If the trap is making a gurgling noise, the water seal may be broken. Check the connections for leaks and ensure that the trap is properly installed.
