Thread: Safety valve for Electric water heater

I know that I would use a Watts 210 gas shut off safety valve in place of the tprv for locations not conducive to installing a drain. Does anyone know of a similar item for electric water heaters that would kill the power?

No luck finding something to kill the power, but did find this:
Water Heater Auto Shut-Off Kit

And this:
Flood Stop Water Heater Auto Shut Off Valve 3/4 NPT - FloodStop Systems

Yeah, I found a few of these too. Not really the right item.
A watts 210 valve shuts off the gas to prevent explosion of the heater and is used in places where it is not practical to drain a T&P like on a slab house with the heater in the center of the place. I often see these with capped off T&P valves and that's VERY dangerous!

Very entertaining to watch, just not at my house please. Or one I've inspected.
