fail where the grab ring (plastic 'crown' shaped piece
with metal teeth in the petals of the crown) seems to have split in 2.


I had one Hep20 fail on pressure test some time back, this was the because
the grab ring was reversed - I had not checked as the fittings were new out
of the bag.

The latest Hep20 have changed the design and you can't push a pipe into a
reversed ring (new type grab rings are green - old type were white)
