Flood sensors

[RalphXhoff]

Is there anyone using a flood sensor at home. Can you talk and share on its durability. I have my friend who badly needs one, they live in a beach house and so wanted one. Suggestions invited...

I use those but also use these as well: http://resolutionproducts.com/wp-content/uploads/manuals/RE119_GE_Flood_Temp_Instructions.pdf
 
Both sensors are pretty simple. When water shorts two contacts, the sensor goes off. They really don't require any maintenance except new batteries every 5 or so years.

I'm currently using GRI 2600 12 Volt DC Water Sensors in my basement.  Never had a leak yet, but I've tested them out and they all seem to work as I'd like.  Sort of expensive, but wayyyy cheaper than a water leak.

Depending on the actual topology of the water sensing element and how often it gets wet, you may need to clean them once in a while. I use one from Visonic and the probes can get dirty enough not to trigger if left long enough. An annual or bi-annual cleaning and inspection should keep them in good order, unless you have a lot of insects or use them in a dirty environment.
