I'm trying to tidy up plumbing with solvent pipes,
yesterday disconnected cistern
went to town, bought 40mm pipe,
it didnt fit,
went back,
bought 32mm pipe,
that didnt fit...

what is the name and size of the pipe from cistern to pan?
what am i doing wrong?

If I use smaller 32mm somehow
should I raise the cistern to get more flow?
