Yup, by design, so you don't try a solvent weld pushfit pipe (wrong type
of plastic)

aaaarrrggghhhh

Indeed... I keep a stock of both, and a few "universal" compression
fittings so you can transition from one to the other.



Buggeration,
Does this mean the 40mm pushfit I have sticking out of the wall from a
sink at work is no good for the boss i've bought for the soil stack?!

Well it's too late now because the new floor isn't coming up! I sense a
bodge coming on.

I see you are supposed to use solvent weld outside, still learning.....

You can use a compression coupler/elbow if there's room. If it is visible and
outside it is at least easily replaceable if it leaks.
