Stop That Leak! The #1 Mistake DIYers Make With Pipe Thread Tape (And How to Do It Right)

1. More Tape = More Trouble

Here’s the shocker: overwrapping with plumber’s tape can cause leaks. Why? Because too much tape thickens the thread and throws off the alignment between male and female fittings.

That means your pipes may not thread all the way in, or worse, they could crack under pressure. Water finds the weakest point—and a jammed-up thread is practically an invitation.

How much is just right? Wrap the tape around the male threads 4 to 6 times—max. That’s plenty for a watertight seal without risking a bad fit.
