Connecting to fixed 4inch soilpipe.

by Barnyard » Sat Aug 20, 2011 11:46 am

I need to insert a 110mm branch into an existing old PVC 4inch pipe but as I understand it the current fittings will not match the diameter. So, as far as I can see, using slip couplings as such to make the joints will not be possible.

What are my options, apart from replacing the existing pipe, please?
