Blue HDPE pipe and frost

[Munroast]

blue HDPE pipe running round the outside of garden, (not even buried in some places) providing the water is turned off that supplies it, and the vairous taps are left open - could frost damage it ? we will often get -10 in the winter, so it will get well frozen.

I doubt it, but a fox might chew a hole in it.

Should stretch enough to avoid splitting. You'll soon find out when the supply is restored.
