smoke detector piezoelectric transducer hack? Answered

I'm thinking of building a basement water leak detector like this:

I wanted to hook it up to something loud like a smoke detector. Is it possible to take adapt the piezoelectric transducer circuit with the water sensor? Any guides. Thanks

HERE is the most relevant Instructable. It looks like the trick is to use the water sensor circuit to trip the Test button on the smoke detector.
