If you have some plumbing repairs to make, there is one thing that you should have on hand – Teflon tape. Teflon tape is a thin tape that is wrapped around the threading on pipe connections. It is meant to seal the gaps between the threads and prevent leaks. Here's what you need to know about using Teflon tape in your plumbing repairs.
Select the Teflon Tape for the Job
When you are shopping for the Teflon tape, you will notice two different colors – white and yellow. White tape is meant for use for plumbing repairs. The yellow tape is to be used for gas line connections.
Using the Teflon Tape
If the Teflon tape isn't applied properly, it will not seal the connection as it should.
Step 1: Clean the pipe threads. The threads need to be free of debris and moisture. Use a clean cloth to wipe the threads thoroughly.
Step 2: Wrap the connections. The tape should be applied to the male end of the pipe – the end that will go inside the other connection. As you wrap the tape around the threads, make sure to do it as smoothly as possible. If there are wrinkles or folds in the tape, you will have a very hard time getting the two connections to screw together and the seal will fail.
Start at the end of the connection – the point furthest from the opening. Wrap going the same direction of the threads. If you wrap it against the threads, it will come unwrapped as you twist the connections together. Keep tension on the tape for a tight fit. Use only one layer of tape on the fitting. Too much tape will make it impossible to get the connections to fit together and you will have leaks.
Step 3: Screw the connections together. If you do not get a tight fit on the first attempt, you will have to remove the Teflon tape and reapply a new layer as it will become damaged as you try to put it together and take it apart.
If you have a pipe connection that is leaking, try disconnecting it and applying fresh Teflon tape to the connection. If this doesn't stop the leak, talk with your local plumbing professional for assistance. He or she will be able to assist you with making the repair and prevent the mold and rot issues that will arise if the leak is left unrepaired. To learn more, contact a company like Cove Plumbing Inc.
