I could've taken pictures just like that one month ago. It wasn't a Floodsafe (although I've been using 3 without incident for a couple years). I had installed a drinking water filter below the sink. It had integral push-in style tube o-ring fittings. I've used these for pneumatics for years. I even threw out the cheap tubing the kit supplied and used the nice 1/8" PEX hose made for refridgerators with the preformed compression end. Anyways, the collar in the fitting that holds the tube blew out. That little line sprayed all day to the tune of almost $30K.
Now that my joists are all open beneath I'm trying to think of the most reliable way to re-plumb. I'm leaning towards running 3/8" PEX (crimp-ring style) to a wall box with the angle valve behind the fridge. The other end will come all the up under the floor to the exposed plumbing under the sink. This way I have no buried connections. I really had gotten used to the big filter and want to do something like it again, preferably with threaded fittings; the outlet would tee off to the icemaker line and to a filtered water spout on the sink. I was looking to see if FloodSafe came as a threaded valve w/o the hose when I found this thread.
Any recommendations on my install? I am nervous as heck about ever having a line break again. What a miserable process.
Ultimately, I think it'd be wise for the insurance companies to fund the development of an affordable automatic shutoff. I envision a system of distributed water sensors in each bathroom, kitchen, utility room, etc, as well as a freeze sensor. Any sensor could trip a 1" shutoff valve on the supply line to the house. One valve for the house - no hose gimmicks. The valve would fail closed, which is to say that it must have power to be open. This could save SO much money. Does anything like this exist? Does it violate code in any way to install an automated valve on the supply line?
