Frequently called Teflon or plumber’s tape, this plumbing tape is typically used for leak repair or self-amalgamation to fix those thin hairline cracks and other non-joint pipe leaks. The physical composition of this tape fills the pipe threads with a sealant that stops water from leaking through the thread’s connection.
Plumber’s tape is ideal for at-home projects yourself, as many homeowners find it useful to wrap around the threading of pipes. But the presence of this tape is more than mere decoration — it helps lubricate pipe connections, preventing them from sticking when you’re trying to disassemble the joint or threading a bit smoother.
Plumbing tape is effortless to use, but there is a right and wrong way to apply it. It’s recommended to use threaded connections that don’t have a built-in rubber seal.
If you find a pipe’s joint leaking, it might be because the plumbing tape has worn out or there’s no tape at all. This is where the plumbing tape comes in.
Once you turn off the water and disconnect the pipe from the joint, remove the worn-out plumbing tape (if any) and apply the new one.
Circulate the plumbing tape on the thread in a clockwise direction and wrap it around the joint about four to six times from the second thread of the bottom. The tape should be parallel with the yarn before reconnecting the pipe. Once done, turn the water on to test for the leak.
One thing to remember is that plumbing tape isn’t an ideal choice for leaks that aren’t at points of joints. For that, you’ll have to shift to silicon tape. Silicon plumbing tape will help create a solid waterproof seal while you can search out a permanent fix.
