I am installing a shower and need to fit a 40mm Strap on boss
to the 4 inch Waste Stack trouble is its inaccesable and there are
that many joints I cant use it but I have noticed plenty of room on
the horizontal stack that goes to the toilet is it ok to fit the boss
on there and run my waste into that or will it cause problems any help
in this matter would be highly appreciated Ta
