Hi all,
I'm attempting to fit a 40mm branch onto a vertical 110mm internal and enclosed soil stack pipe. I'm trying to work out if the 110mm pipe already there is ABS plastic of PVCu, but I've removed quite a lot of the plasterboard on the boxed in section and I can't see any writing on the pipe. The 110mm pipe itself is black, but every 400cm or so it has a coupler (part no. SH43) which I understand is a PVCu push fit coupler). I've no idea why they used lots of short sections of 110mm vertical pipe with lots of couplers instead of just a long section of pipe, seems weird.
I'm lead to believe that black 110mm pipe is usually ABS, so I should be ok with solvent welding on a 'strap-on' boss. My preference is solvent-weld because space in the boxed in section is too small for a mechanical (e.g. McApline) attachment both because of space and access to tighten it up.
Any idea if I can rely on the black pipe being ABS or should I be cautious? Also the Solvent Weld Glue I have says it's ok for ABS and PVCu but people seem to say it wont actually work on PVCu.
Thanks,
George S.
