Work very good and easy to install

easy to install. works great

Works well with my water filter system. Like it a lot . I recently had 2 sensors, one at water heater and one behind washing machine. Planning to add more at the kitchen and fridge.

The former owner never put a floor drain in the basement equipment room where the well pressure tank was located, and we had to had some heavy filtration due to the fact that he cheaped out and didn't drill the well deep enough to get away from a bad upper stream. So have always been worried about a major water leak since there is no where for the water to go.

Had a bunch of other major plumbing rework done to make way for adding a softener so had the plumber install the valve for me. Works extremely well. Very sensitive just a drop or even moist fingers will trigger the alarm and close the valve.

Of course you always need to test this periodically to make sure that the valve is not frozen so you don't get a false sense of security, but the controller will exercise the valve every 30 days to make sure that it doesn't seize up due to mineral content in the water.

Actually had an issue after it was installed. The plumber used a schedule 40 female threaded connector since they ran out of schedule 80 on the truck. He tried to be careful with tightening it but after 3 days the PVC connector developed a crack and I didn't see it until FloodStop had closed the valve and sounded the alarm. Plumber came back and replaced the cracked connector with a schedule 80 part and we were back in business.

Fortunately it wasn't a truly major leak, but is was leaking about 5 gallons in a 8 hour period, so without FloodStop it could have been a big mess.

Can sleep a bit easier with FloodStop and the sensors in place. Going to add a couple more remote sensors for the dishwasher and laundry areas.

Also I'm planning on using the signal output to control a 220V contactor relay that will interrupt the power to the well pump when a leak is detected. That will take care of any potential leak between where the well pipe comes in and the pressure tank since the FloodStop valve is obviously only on the output side of the pressure tank.

Very cost effective solution.

The plumber I used has a different system that he sells, but it would not work in my case. That system was based on water flow for a period of time, so you would set how long you want to allow water to flow before it would turn off. With our backwashing filters we would have had to set the flow time so high it would defeat the purpose of detecting a leak (and his system was about $1600!!)

I would buy this again if I needed it in the future.

Installed easily. I tested it several times, and it is very - very sensitive to any water - shutting the valve off right away.
