Hi All,
We recently purchased a Grohe sink and sink trap. However the Grohe pipe is smaller than the standard fitting. Have tried local plumbers merchants and supplier to get an adaptor but no one seems to be able to supply one.
looking for a 32mm - 34mm adaptor.
Any suggestions?

Bathroom / Vanity unit?
Should work with this;

That fitting under the plastic elbow in the picture, is the fitting I think you use to connect the horizontal pipe from the trap, to the pipe coming out of the wall.

You will either need a pipe socket to 40mm or 32mm thread. (depending on the thread size of the fitting )

That's how we do them.
Some people just push the trap pipe inside the PVC pipe and silicon it.
I wouldn't recommend this method
 
More explanation:
The fitting in the bubble wrap is the shroud ( left side of pic )

Fitting under ( right side of plastic elbow) is the fitting that seals the chrome pipe to a threaded fitting coming out of the wall

So that fitting next to the elbow threads onto a typical 1 1/4" compression fitting and acts as a push fit adaptor?
