Another frustrating day in the renewal of our en-suite!!
I've found the old waste pipe from the shower to be 43mm (as printed on the outside of the pipe). My question is whether this 43mm plastic pipe can fit to 40mm pipe using a (presumably) 40mm joint?
I ask as I can't find any large supplier (B&Q, Homebase, Wickes etc) which sells 43mm pipes.
Any thoughts very welcome!!
