McAlpine Macfit MAC-1 WC Straight Pan Connector | Screwfix 

Why the concertina look? My builder fitted either this or similar, but doesn't the concertina cause build up? Why not straight - new extension

Okay, I've fitted one of these, and it's still leaking. Any ideas, suggestions, or remedies would be appreciated.

Just so I'm clear, does the outlet go directly into the socket of the rigid 118mm pipe? Cheers.

How does one get so enthusiastic about such a product?
