I ended going with the Dam-it flood sensors. I had Epic System Tech F/K/A Strongman Security install three of them one in the electric closet one in the boiler room and one in the bathroom in the basement. They integrated into the Control 4, and so far they have been working great. The only problem with them is they are battery operated with two AA batteries, so you have to check on them to make sure the battery is not dead. Another thing is once the sensor goes off, you have to pull the battery to stop the flood sensor light from blinking as that will drain the battery. I'm going the install the Duracell optima batteries in the sensors to get longer battery life. Please see the Dam-it flood sensor link below and Epic Systems Tech.
