Locate the drain body that came with your tub drain kit. Insert it through the flange from beneath the tub. Use a screwdriver to securely fasten it while ensuring it remains level.
Step 4: Connect the Drain Pipe
Using the appropriate size PVC or ABS pipe, cut it to fit between the tub drain and the main drain line. Make sure the pipe is slightly sloped (about 1/4 inch per foot) toward the main drain to promote proper drainage.
Step 5: Fit the Trap
The trap connects to the tub drain and the main drain. Use the appropriate fittings to connect these sections securely. Ensure that all fittings are watertight by applying plumber’s tape where necessary.
Step 6: Connect to the Main Drain
Carefully connect the drain pipe to the existing main drain. Depending on your plumbing system, this may involve using a coupling or band clamp to secure the join. Ensure that the joint is properly sealed to prevent leaks.
Step 7: Double-Check Your Work
Before testing, make a final inspection of all connections to ensure they are secure. Check that everything is aligned and there are no tools left in the installation area.
Step 8: Turn On the Water Supply
Once you are confident that everything is fitted together correctly, turn the water supply back on. Test the tub drain by running water and checking for leaks at every connection point.
Troubleshooting Common Issues
Even with the best preparation, you may encounter some common problems during or after installation. Here are some solutions to help you troubleshoot:
Water Leaks
- Cause: Often caused by loose fittings or inadequate sealing.
- Solution: Tighten any loose connections and check seals. If necessary, reapply plumber’s tape.
Slow Drainage
- Cause: Improper slope or blockages in the pipes.
- Solution: Verify that the drain line has the correct slope, and clear any obstructions.
Maintenance Tips for Your Tub Drain
Once you’ve successfully connected your tub drain to the main drain, ongoing maintenance is essential to ensure everything continues to function without issues. Here are some tips to keep your drain system in excellent shape:
