there is a $10 audible water alarm at home depot with also low battery
alert, it uses 2 contacts and a 9v battery.

I have something like this, at about this price. I attached the
original sensor in the basement sink (which can fill up when it rains
enough, including today (since I had forgotten to plug it) or might
fill up if the drain clogged and the clothes washer put both the wash
and rinse water into it) and I made another sensor (two pieces of
metal on an insulator, glued to the side of it) for the sump pump pit.
That way either sensor trips the alarm. I lengthened the wire from
the sensor to the alarm so that it went from the basement, along the
water pipe, to the cabinet below the sink, and put the alarm there.

Of course the battery went dead about 10 years ago, and I've been too
"distracted" to replace it. But otherwise it is a very good system.

Hi Folks, I would like to put a water sensor in a dry well that would
indicate if there's water in the well. There would be either an audio or
visual warning light or sound. Does anyone know of any products available?

Thanks
