Installation Steps:
- Preparation: Turn off the water supply to the sink. Place a bucket under the existing drain to catch any residual water.
- Remove Old Drain: Carefully disconnect and remove the old drain pipe assembly.
- Assemble Components: Attach the J-bend to the sink tailpiece using the provided nuts and washers. Ensure washers are correctly seated to prevent leaks. The captive nut design facilitates this step.
- Connect to Wall Drain: Connect the straight pipe section of the S-trap to the J-bend and then to the wall drain pipe. Adjust the length of the straight pipe if necessary by cutting it to fit.
- Tighten Connections: Hand-tighten all nuts, then use a wrench or pliers for a final snug turn. Avoid over-tightening, which can crack plastic components.
- Test for Leaks: Turn on the water supply and run water through the sink. Carefully inspect all connections for any signs of leaks. Tighten connections further if leaks are detected.

5. Maintenance
Regular maintenance helps ensure the longevity and proper function of your S-trap drain pipe.
- Regular Cleaning: Periodically flush the drain with hot water to help prevent grease and soap buildup.
- Check for Leaks: Inspect all connections annually for any signs of drips or moisture. Tighten connections as needed.
- Avoid Harsh Chemicals: Do not use harsh chemical drain cleaners, as they can damage plastic pipes and seals. Use enzymatic cleaners or a plumber's snake for clogs.
- Clear Obstructions: If a clog occurs, disassemble the S-trap to manually remove the obstruction. The captive nut design makes this process easier.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Leaks at Connections | Loose nuts, improperly seated washers, damaged washers. | Ensure nuts are tightened securely (hand-tight plus a quarter turn with a wrench). Check that washers are correctly positioned and not damaged. Replace damaged washers if necessary. |
| Slow Drainage or Clog | Accumulation of hair, grease, or debris within the trap. | Disassemble the S-trap and manually remove any obstructions. Flush with hot water. Consider using a non-corrosive drain cleaner. |
| Sewer Gas Odor | Dry trap (water evaporated), loose connections, or improper installation. | Run water to refill the trap. Check all connections for tightness. Ensure the S-trap is installed correctly to maintain a water seal. |
