nout wrong with that. couple of turns of ptfe on the threads and couple of turns on the olives
only couple of turns if it was belt and braces then PTFE & paste
i was tought you should do 10/12 turns on the threads with tape and a smudge of paste on the jointing side of the olive

i only done 3 turns of PTFE sealed nice and no leaks

Should be a full bore valve, I agree with earlier post preferably lever valve, full flow none the less.

If I had seen this on a job I'd think diy. PTFE around olives only.

If you were taught ptfe around the thread can you explain the reasoning behind this.

Thats why it was £30 full bore lever valve is a fiver(ish)

You don't want anything on the threads as the threads are only there to assist the squeezing of the olive.
Paste on the olive great!

You shouldn't ever put anything on the threads of a compression joint
 
Surely the pic i in the wrong place. Shouldn't it be in the hall of shame? Honestly, that's worse than most DIY jobs I see.
 
This should be a question on your brain teaser thread..... Why is there ptfe on this valve?
 
you should never have metal on metal water can and will find its path to leak metal on metal thread = water to travel up the thread thats what i was shown by a plumber to do it this way. we all have our own way of doing things

That's on a thread to thread joint. Not a compression.

Your are referring to the type of joint like where an outside tap screws into a wall plate elbow. (No olive)

Never have metal on metal lol
What material is an olive what material is a copper pipe
There a clue in the name lmao

The seal is between the olive and the copper pipe though, paste or ptfe is used to take out slight imperfections in the pipe, there should be no water coming through the thread if there is water slightly nip it up, or dismantle bit more paste or ptfe.

Whoever told you this is wrong.........

Surprised you've got any left.

In all seriousness, and I mean this now, if you want to become a plumber you're best learning from someone with lots of experience and preferably qualified. Forget everything you've been taught so far and start over from scratch, get yourself onto a college course too and don't be tempted by fast track offers.
 
im on the card for a 2 year course at my local college.
the guy i worked with done all his valves like this and tails ect never had a leak that i know of?
when i got into college my plans are to start off from scratch because im there to learn and there there to teach!

its just that way iv been shown..

Well if you're willing to accept that what you've learned so far is wrong and knuckle down in college and fully focus on learning and listening you should come out the other end with some well earned certificates. I hope one day you can come back to this thread and see the funny side. 😉

Good luck.
