Hello -- I have to fit a heavy wall mounted bath filler. It has a 1" BSP piece to go through hole in wall and then a brass backnut screwed on behind the wall clamps it on. After allowing for the thickness of backnut, there is 25mm length of the 1" BSP.
If I allow for 12mm board then 12-13 mm tile and adhesive, that will not leave any thread left to get the female BSP tee piece on to supply the water. I was thinking of using 12 mm WBP Ply rather than plasterboard for the stud wall surface and rebating into the outside face of that a small sheet of say 3mm thick brass, putting a hole in it for the 1" BSP, and thus only having around 15-16 mm thickness (12-13mm tile + 3mm plate), which would allow 9mm of thread to get the tee on (that's approx 3 turns).
How would this type of filler normally be fitted? Any better ideas?
Thanks
Peter
