Can't say I've ever seen anyone try this with plumbers tape . . . although my sister, according to the messages she was sending me, did I pointed her in the direction of self-amalgamating tape for her leaking basin drain. I guess it will be a temporary fix for the next couple of decades . . .I love the accuracy
PTFE tape can also be used as a temporary short-term solution to help seal plumbing leaks until further work can be carried out. It is generally applied to a joint's exterior to minimise further leakage. However, it is not designed to be a long-term measure for fixing degraded, damaged, or incorrectly fitted joints.
