    If you are proceeding then go and get 3/4" copper olives, much easier to compress that brass. Gate valves will be useless in a few years if they're not regularly used, if you really want valves then swap them out for lever.

    so my plan now is remove both gate valves and replace with pegler lever arm, hopefully tighten more on the olive and remove shower valve elbow and wrap a bit more thread on the male thread.... let you know my progress :) thanks all for your advice

    Fingers cross everything seems OK, I didn't replace the gate valves as the lever ball was heavy and weighing down on the pipes, loctite 55 seems to work really well on the elbow compression , I wrapped the same amount as the ptfe before and feels really solid when tightening, and the gate valve is not weeping as I could tighten more with 3/4 copper olive . I'm really hoping this will hold now as it took me so long to sort out. I like to say thank you guys for your advice :)

    I have to say that all your woes would be solved if you used a soldered 3/4" to 22 mm fitting to convert the pipe to 22 mm before it goes into the gate valve.

    That is probably what most better plumbers would do!

    Of course some would continue with your bodge and add some gas PTFE/ Locktite 55/anaerobic tape and when it weeps again after a couple of days they will not answer their phones!

    The thing to remember is that not all compression cones fit properly into the different makes of valve. The nut was more than likely running out of thread before it tightened up the foreign cone fully. Glad you've got it sorted now, though it's always nice to know where you were going wrong.
