OK I give up !
I am in the process of replacing a bath and need to extend the existing waste connection. (The old bath had a central plughole, the new plughole is at the end of the bath). In haste I have purchased a 40mm pushfit coupler together with 40mm pipe, elbow, trap etc. On closer inspection I have found that the existing waste pipe has an external diameter closer to 45mm !
Any ideas how I can couple this to my new fittings ? I have searched Screwfix etc. in vain.
Thanks in anticipation.
