The integrity of the O ring is vital. So pipe must be smoothly cut

I've not had a problem with any, even the cheaper B&Q branded ones.



Ok I'll put it down to a dodgy fitting and stop worrying then...

The O ring looks ok, but the fitting didn't seem as secure on the
pipe as the genuine ones, I wouldn't have used it if I hadn't been
in a hurry

Maybe the grab ring was distorted..



Maybe, although it didn't really feel very secure in either side of
the fitting. I was careful to cut the pipe square, using the cutter
and used inserts. No sideways pressure on the joint either.

Possibly it needed a different method of fitting, or maybe it
doesn't mate very well with Speedfit pipe. I'll have a look in the
shop and see if they have any instructions, although I don't think
I'll want to use that type again...

The only trouble I ever had was the other way round i.e. normal comp
fittings onto speedfit pipe.
I did have the support sleeve in place but no amount of tightening would get
a good seal in 2 places.
Replaced pipe with Hep2O and it was fine.
