I used some Hep2O for the final feed for a greenhouse at the end of the
garden. the pipe was never bothered, but one time when the water froze
the pipe pushed out of the tap compression joint enough so that it
leaked quite dramatically on thawing.

Yes, having used Speedfit and Hep2o, the former is quick and the latter is
more of a faf but less likely to be blown apart.
