This company makes some really nice water alarms. Some models come with low
voltage relay contacts that can be used to trigger other things.

I think McMaster-Carr sells them.

Does anyone know of a water alarm that can be rigged so that when tripped,
will shut off a 240VAC well pump?

It would be nice to have one installed in the basement, so that in the
event
of a pipe burst, the pump would be off limiting that amount of water that
could get out...
