First post so hello to all!

Right here we go.............

I have a Geberit UP320 concealed cistern, it came supplied with a flush pipe which has a outer diameter of 45mm.

I have a back to the wall WC from Bathstore which requires a standard 38mm (1½”) flushpipe...........obviously I have an issue here as flush pipe supplied with cistern wont fit toilet and vice versa!

I need some help/advice?

Is there something like a flush pipe reducer around i.e. 45mm down to 38mm

Whats my options?

I've seen a flexible flush pipe from B&Q but think this is gonna be standard size and maybe wont connect to the cistern.

Help please :confused:

You have concealed cistern from Gerberit and a pan from bathstore if I'm reading your post right?
I doubt if you will find a flush pipe reducer though you might be able to bodge it. Or maybe change the internals of the cistern.
