Thanks! I'll look around.


Thanks, Aaron, but unfortunately those are mostly whole-house valves designed to attach to your main supply. They're super expensive because of it. I've definitely considered one, though. They make one with ZWave functionality, which means I could set up ZWave water sensors in places I might be concerned about flooding, and if they detected any water they could send the signal to shut off the whole house valve. Pretty neat. Sadly, the ZWave valve is about as expensive as those (around $500). I'll have to hold off on that!
