Do you have an burglar alarm? There are addons that do this for them,
including wireless ones.
We've got a bunch of these:
They're really loud, so they might be enough. The sensor is just a
pair of contacts. Water completes the circuit, and sets off the
beeper. You can cut the wires and splice in a longer wire. (lowes
webstie says 100'. I expect the limit is because it's driving the
beeper with the current sent through the sensor. If you know any
electronics, that's easy to fix...)
