I'm fitting a wall mounted wc into my bathroom, using a grohe mounting frame, and I'm puzzled what the best way to deal with the small maybe
35-40mm height difference between the right angle grohe wc socket clipped into the frame, which is about 90mm diameter, to the 4" plastic waste pipe feeding into the soil stack. The frame is at lowest setting, and the waste pipe to stack is about 35/40mm lower. I guess I need a flexible coupling that can fit onto a 90mm pipe, and fit into the 100mm waste pipe at the other end ? Any ideas ?- posted
