I have been looking at the waste trap supplied as standard with a Bath Store
shower tray. I have been helping install some Bath Store kit.
The outlet of the trap has a black item inserted which fits via a compression
fitting and appears to to be a converter from a narrower diameter to a wider
However, neither the "narrow" end is 32mm of the "wide" end is 40mm.
Does anyone know what the true dimensions are? What will they fit?
More to the point: how can this item be connected to regular 40mm piping?
Ideas, opinions, please
If this isn't fixable, then some questions:
What are these traps? Where does Bath Store get them from?
