To PTFE or Not? FAQ

I suspect being attached to a heated building wall has something to do with it, as well as wind/sun.

That's one of the next jobs on the list once I'm confident I've sorted out the water hammer device installation.

Back outside tap is quite old (~1980s) and very stiff so I've bought a replacement. But not had any freezing issues despite it being in a fairly cold spot - cross-fingers.

Lots of PTFE tape at hand for that and I'll take care to wind it on the correct way, something I didn't pay much attention to with the Shock Arrester which my memory says I did it from the inside to the outside.

Thanks, and to others.

Well if it can be done wrong then I did it wrong :(

Fitting the shock arrestor involved 4 compression fittings two of which were seeping.

I just taken it all apart, used new pipe and olives, ensured everything clean, used the lightest dab of vaseline and this time ensured I did not overtighten by just watching the drips of water and firming up until they stopped. I think I had squashed the olives on my first attempt.

The shock arrestor (straight not tapered threads) came out all too easily with the previously wound PTFE tape all pushed to the end and as far as I could tell wound anti-clockwise. I paid more attention to winding the tape on clockwise and not "roping" it first.

Two hours in and not a drop in sight.

Now will I remember these nuggets of wisdom the next time I do a job in 5 years time? I didn't from last time.
