That is what I am afraid of. However both ends would be very visible and
any blow off would soon be seen.

A hose will use an awful lot of water overnight...

I think you can get check valves that stop the flow if the pressure drop
across them rises above a given amount. The pressure drop being
proportional to the flow rate.

FWIW, I have been using a PIR sprinkler to keep rabbits off my veg plot
and it has worked fine for a fortnight using a standard Hozelock hose and
connectors. The tap is on 24/7 but the water only escapes when a varmit
crosses the detector's infra-red field -- which seems to occur about once
every couple of hours on average (but I can't be sure). Nothing has blown
apart yet! (And my beans haven't been eaten yet!!)


Now that looks promising :-))

All I need to do now is get some suitable fittings for what I want to do :-)

Thanks everyone
