Hi, got a wall outlet for my Shower from Screwfix.
http://www.screwfix.com/app/sfd/cat/pro.jsp?id=58943&ts=18786How does this stay solid when fitted. What is it that stops it moving/twisting/pulling away from the wall?
Also outlet hole seems very small diameter. Seems daft to have 22mm pie to valve, then to go through this small hole. Will I get decent pressure and flow with this?.
Thanks
Simon
