Step-by-Step Guide on How to Fix Threaded Pipe Leaks
1. Turn Off the Water Supply
Before you start, make sure to turn off the water supply to the leaking pipe. Locate the water shut-off valve, which is often found near your water meter, and close it completely.
2. Drain the Pipe
Drain the pipe by opening the nearest faucet to release any trapped water. This ensures a dry working area and better grip on the fittings.
3. Clean the Threads
Once you disassemble the leaking connection, clean the pipe threads thoroughly. Use a wire brush to remove old thread sealant, tape, or debris. Clean threads allow for a better seal.
4. Apply Thread Sealant or Plumbers Tape
Wrap the threads with PTFE tape about 2-3 times in a clockwise direction. Make sure the tape covers all threads but doesnt block the water path. Alternatively, you can use a liquid thread sealant for added protection.
5. Reconnect the Fittings
Reconnect the joints, tightening them snugly with a pipe wrench. Avoid overtightening, as it can damage threads and cause more leaks.
6. Test for Leaks
Turn the water supply back on and observe the pipe for any leaks. If you notice any drips, check to ensure that the fittings are correctly aligned and sealed properly.
