Hi.
I'm fitting a new shower valve (Grohe Rapido T universal) it has 1/2" inlet and outlet ports to connect to so have got some 15mm x 1/2" male unions (I think that's the correct term) both straight and elbows. I've tried to find out how to fit the brass fittings and there's lots of conflicting info out there (perhaps some of it is US so based on NPT - but I'm pretty sure these are parallel threads). The questions I have are:
1. Should I use anything on the fittings (PTFE, pipe dope)
2. The elbows seem to go in hand tight and then stop after about a quarter turn with a spanner so how do I get them to point the direction I need them to
3. Probably hard to answer this but how tight should they be
Thanks
