How do you stop PVC threaded fitting from leaking?
To stop a PVC threaded fitting from leaking, follow these steps:
- Identify the Leak:
Locate the exact point where the threaded fitting is leaking. Ensure the leak comes from the threaded connection, not a crack or hole elsewhere in the pipe.
- Turn Off the Water Supply:
Before attempting any repairs, turn off the water supply to the PVC pipe to prevent further leakage.
- Loosen and Remove the Fitting:
Use a wrench to loosen and remove the leaking threaded fitting carefully. Turn it counterclockwise to unscrew it from the pipe.
- Clean Threads:
Clean the threads on the fitting and the pipe using a wire brush or a cloth to remove any dirt, debris, or old thread sealant.
- Apply Thread Sealant or Teflon Tape:
Wrap Teflon tape over the pipe’s male threads in a clockwise direction or apply a thin layer of thread sealant. Make sure all of the threads are evenly and completely covered.
- Reinstall the Fitting:
Turn the fitting clockwise and gently screw it back onto the pipe. Use a wrench to tighten the fitting safely; however, be careful not to overtighten, as this could harm the threads.
- Check for Leaks:
After turning the water supply back on, look for any leaks. If the leak continues, you might have to repeat the procedure or consider using a different thread sealant.
