I can well bet this question has been asked several times before but the problem is finding the right words for a search.
I've had to replace the basin in my shower room. It came to me second hand 30 yeas ago and might even had a tiny crack then but something has triggered a significant crack recently.
As is the way of these things it takes as much effort getting the old one out as getting the new one in :>(
Anyway I've now got to re-work the plastic drain.
My problem is that I used a glue type pipe for the old one, and is 34.6mm od, and the only pipe I have anywhere near that is 36.4mm od with a 2mm wall. I do have access back to the 100mm drain stack where there is a push fit onto a 34.6mm diameter spigot.
I could redo the run quite easily, but I don't know what to buy - can someone give me guidance please.
Many thanks
