I'm practicing some connections on water lines, but I'm a bit worried the parts I have are bad.
Here I finger tight the parts and then was able to do just a half turn with the channel lock before felling like it was "right". I'm not sure if that was enough or if I hit the "neck" of the male threads.
Below I show how the tape got after that, in the left side I used 15 turns of tape and on the right side just 5 turns. Both were cut around the last thread, does that indicate that the seal was done? How much tape is enough?
