Document: I have installed Floodstop in my water heater and tested it a few times. Each time, the valve closed which shut off the water supply. Although I have not experienced water heater leaks yet, I feel confident that Floodstop will do its job. Installation is simple and quite easy.
I recommend screwing a few extra inches of pipe into the Floodstop and then soldering the pipes at that far end so the heat won't fry the electronics while you're installing it. The pipes get pretty dang hot during installation.Anyway, this thing works perfect. I tested it by dropping a single drop of water on the sensor, and the valve closed in under 2 seconds. If the water stays on the sensor, the alarm continues to sound.
My water heater burst at my old house, and it caused my garage ceiling to cave in from all the water pouring out. I was lucky the water heater wasn't located over the living area. Now I'm paranoid at my new house since the water heater is in the attic above two floors of living space.I installed the Floodstop shutoff valve on my water heater and put the water sensor in the pan at the bottom of the water heater. The electrical parts are sooo easy to connect.
Seems like a good product. Happy so far. Would recomend this product. Looking to add other sensors to other parts of the house.
If you don't have any hot water, it clues you in that something must have triggered the shutoff valve and you can investigate. Every home that has a water heater over the living area should have one of these installed! Insurance rates would probably go down.
Answer: no
