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

the tap is screwed in very tightly to the wall plate so that it will not

or leak - and the tap is itself vertical?


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 allows the tap to seal completely over quite a few degrees of rotation.

If it isnt reasonably tight when vertical, you can put some more tape on
the thread so it is tight when vertical.
