When you screw in an outside tap into the wall plate, how do you ensure that

Ptfe tape on the threads :-)

Yes - but how does that ensure that when you tighten the tap up it is at 12
o'clock and not half past six?




It just needs to be tight enough to make sure that it doesn't;
a) leak
b) move of its own accord

It will get even tighter over time - corrosion, etc.

Personally, I prefer Boss White and hemp over PTFE tape for joints where
alignment matters. Greater tightness vs number of turns.
