Hi all,
Ok, I’m electrically qualified so please excuse me if I use incorrect plumbing terms or expressions.
Today’s stupid question relates to the installation of a thermostatic shower by Grohe.
The unit in question is an exposed bar that screws onto two s shaped eccentric tails or stubs that screw into the wall plate. The instructions always say to wrap ptfe tape onto the threads and screw into the wall plate.
Now, in order to achieve 150mm centres and level, it means that the fittings never tighten down onto a seat. That is, the fittings might only be 90% into the wall elbow.
That might work short term but I imagine the fittings are not exactly tight and in time, they’re going to move and leak.
To make things more difficult, the Grohe S unions seem to have serrated threads that demolish the ptfe tape.
So, how do you install S unions firmly and leak proof?
Thanks in advance
Trevor
