Hi there need some DIY advice from some of you experts.
I'm just about to fit a new shower mixer and outlet, which will be partly recessed in a brick wall behind Marmox type waterproof cement boards, installed by dot and and dab and wall fixings. The mixer valve has 3/4 BSP, so I purchased some 3/4 BSP to 15mm compression valves from SF. I'm fine with the copper pipework to connect all up, but just not sure about the connection. I've searched various forums and the consensus seems to be loads of PTFE or Loctite thread to seal is all that is required. The reason I ask is would nobody looking at the pictures use any type of washer in between them? There clearly is room for one between the two flat edges? See pictures.
2nd question is about the shower outlet. Same type of question really. I purchased an end feed female 1/2 BSP to solder onto the outlet copper I will run from the mixer valve. I'm also aware I need to place this carefully to sit in the right position in respect to the finished tile level. From looking at the distance (side on) at the fitting fully screwed home in the female BSP, it needs to be about 5mm behind the tile level to sit flush. So the question is does this again seal up just using PTFE / loctite or could I use a rubber washer as there are two flat surfaces that butt up against each other perfectly inside. Will add pics...
Thanks
Paul
