Bar mixer valve

[stebed]

I am currently fitting a mixer valve shower, the valve connects to the hot and cold feed via dogleg connectors. My question is I cannot fully tighten the dog leg connectors as they rotate out of position when they are tightened. My description may sound unusual but if you have used these fitting you will know what I mean. I think the way to use these connectors is with PTFE tape and get them as tight as possible.

Any advice would be appreciated.


Thanks

yes use ptfe or liquid ptfe, but i can't see how they are moving if you hold the dogleg with adjustables and tighten the nut with adjustables.

What have you got the dogleg connectors coupled up to on the fixed pipework?

I have just installed pipework for the same thing and used tap connectors.

I was able to tighten the nut on the tap connector, while I held the dogleg connector in position with a spanner, on the square part in between the two threads. This seemed to work fine.

I have connected the dog leg fittings to 90 degree elbows which have a fixed nut on the end hence I have to rotate the dogleg fitting to tighten it. I think the PTFE will do the trick just wanted to check.

Thanks

you'll be better using a wall plate then you can secure it to the wall.
your need to make it secure if it's a bar mixer
