Transcript:How to Apply Teflon Tape to Prevent Leaks

Hi I'm Debbie Anderson for About.com.

When to Use Teflon Tape

If you have ever just recently repaired a plumbing problem only to discover that the new plumbing joint connection you just repaired is now suddenly leaking all over again, then today Im going to show you how to properly apply Teflon Tape, also commonly referred to as Plumber's Tape to avoid future leaks after already having repaired a plumbing problem!

Supplies for Applying Teflon Tape to Prevent Leaks

For this task, you will need:
  • a roll of Teflon tape
  • a clean rag
  • paint thinner
  • a pair of scissors
  • rubber gloves
  • and a pair of adjustable pliers

Instructions for Applying Teflon Tape to Prevent Leaks

First, turn the water off to the faucet or fixture that needs repaired. Next, use your adjustable pliers to unscrew the fixture's connection.

Use a clean rag to remove any old plumbers putty or Teflon tape left on the threads of the plumbing joint connection.

If simply wiping the threads off with a clean rag does not do the trick, put on a pair of rubber gloves and apply a small amount of paint thinner to your rag to thoroughly wipe down the threads of the plumbing joint connection.

Once the threads are clean, apply Teflon tape to the threads of the plumbing line where a new fixture or pipe is connected while making sure to wrap the tape in the direction that the fixture or connection will be tightened. If the tape is wrapped in the opposite direction, it may tear when the fixture or connection is tightened down on the threads, causing future leaks.

Next, carefully hand-tighten the new fixture or pipe connection onto the Teflon tape covered threads. Although you may want to use your adjustable pliers to make sure the connection is good and snug, be careful not to over-tighten it or you may still wind up with a leak all over again.

Finally, turn the water back on and inspect the plumbing joint connection for any leaks.

And there you have it. No more leaky plumbing connections.
