Have a leak on one of the brass fittings - so will fix that first . Does the mixer need hot and cold simultaneously ? I.e prevent the knocking ? . I have no hot available but could stick cold on the hot feed ... I have a feeling that the more "right angle" bends you have and less sweeping curves, the more knocking you are prone to.

PeterW Posted August 4, 2020 Share Posted August 4, 2020 Is your hot pipework not connected ..? Or do you mean you have it all connected but it’s not hot ..? Link to comment Share on other sites More sharing options...
Russell griffiths Posted August 4, 2020 Share Posted August 4, 2020 You need to flush it through take off the capped ends and run it for a while, don’t cap them first or your just testing if it’s air proof. I think you should change that pipe work it looks proper shit (sorry) dont rush and bodge at the last leg. If the shower head head is too low stick one on the ceiling. C,mon lad do it right.

You mean the nasty 2 90 tees ? Can’t see another way of doing it . Runs too short . Pipe not flexible enough Link to comment Share on other sites More sharing options...

It’s all curves up until the mixer as it’s a single run per feed with no joints . Link to comment Share on other sites More sharing options...
Pocster Posted August 4, 2020 Author Share Posted August 4, 2020 Just vaguely remember @Nickfromwales saying not to attenuate flow with the manifold . Not on site at the mo - but possible manifold tap not completely open ... Link to comment Share on other sites More sharing options...
PeterW Posted August 4, 2020 Share Posted August 4, 2020 That last pipework to the outlet is a bit crap and will cause air to get trapped. You can get a straight Hep2O to BSP connector, then use a couple of elbows downward. Link to comment Share on other sites More sharing options...

Pocster Posted August 4, 2020 Author Share Posted August 4, 2020 I’ll order some 135 see if that helps Shower head can’t be ceiling mounted as ceiling on an incline Link to comment Share on other sites More sharing options...
Pocster Posted August 4, 2020 Author Share Posted August 4, 2020 Decided therefore to test the shower head . Indeed opening the manifold did seem to alleviate the knocking . One thing I noticed is that with the shower set to fully off a small trickle still runs through the shower head . Can’t see any obvious adjustment for this ...

Sure that is not just the shower head draining down? They have an annoying habit of dripping for a long time, or start dripping in the middle of the night hours after last use. 1 Link to comment Share on other sites More sharing options...

Nothing against it and it looks great. If my lad has a shower he uses it all the time. Means when I go in and use the handset straight after I get the occasional nice cold drip from the water in the rainfall head. 1 Link to comment Share on other sites More sharing options...

Pocster Posted August 4, 2020 Author Share Posted August 4, 2020 (edited) I forgot how much brass fittings like to leak . Each fitting should come with its own roll of ptf tape . Maybe in the distant future all mixers / taps etc. are hep20 ready ... ? Edited August 4, 2020 by pocster Link to comment Share on other sites More sharing options...

Pocster Posted August 4, 2020 Author Share Posted August 4, 2020 Trays not in . But roughly height from floor to shower head is 190cm . I’m 6ft 1” so seems low too me . I can reposition it a bit further up - gain maybe 70mm That too low ?? Link to comment Share on other sites More sharing options...

If you’re desperate you could always make them off with a smear of LSX too. Have you used a stem elbow into the shower fitting then once you’ve converted it to a Hep2O socket ..??
