Marty,
You could always put in an automatic vent at the top of the pipe outside
the wall. That would allow any water in the pipe between the vent and
the ditch that is not below the outlet end of the pipe to drain out.
Another thing you could do is put a check valve in line with the pipe to
keep the water from backing up into the pump.
I was talking to our propane delivery guy yesterday and he told me that
about once a year, when we get our first hard freeze, that the hose
couplings on their delivery trucks leak really badly because the hoses
shrink, making the clamps loose. Is it possible that you clamps are
loosening up, allowing the hoses to blow off?
