I had the "pond emptying thing" often enough that I gave up and constructed my
filters to overhang my pond so overflow goes back into the pond. No hose leads from
the pond to anywhere outside the pond. No pond emptying so far. Ingrid

Yesterday the hose from my pump to pressurised filter came of putting

Fortunately I was about and was in time to switch of the pump before

I was wondering if anyone had come across a device to cut off the pump
if the water level got too low?

Can't help with a device, but in addition to normal hose clips, my pipes are
also secured with cable ties to the body of the filter. Filter also stands
on a slope to the pond, so any leakage runs back in. Well, that's the theory
anyway
