Got a 110 mm brown UG pipe stub coming up through sub floor concrete. Want to connect a shower waste via a strap boss just above the concrete so that the pipe can run in the insulation and under the top screed. Will be very inconvenient if joint leaks! But I have doubts as to whether you can successfully solvent weld to brown pipe as a trial of two old bit of brown pipe really didn't see to show any chemical bond the adhesive was just filling the gap not having softened the plastic as happens with airfix models. Mind you same occurred on a trial piece of 110mm grey plastic soil. I may be able to pull the brown stub out (it was wrapped in thin insulation) but what is the point if grey pipe does not solvent weld either?
Any one got experience of this?
