Any experiences, good or bad, with the Watts FloodSafe for water
heaters? -- shown here, for example:
It's supposed to detect even tiny leaks and cut off both gas and water.
I don't have any direct experience, but recently was looking into
similar for washing machines. I found that there are also whole
house products that function by being placed on the water main pipe
after it enters the house. These units in turn come in at least two
varities. One uses wireless sensors which can be AC or battery
powered and placed anywhere within range. The other uses
intelligence to monitor water flow and if even a small flow continues
for more that a programmable time, it will cut it off. The obvious
advantage to these is that for a little more cost they can be used to
guard against a variety of leaks: water heater, washer, ice maker,
dishwasher, etc., without having to install a cuttoff type unit for
each one. Some can even be connected to the internet or your alarm
system to send an alarm. So, if you have multiple locations to
protect because of wood floors, etc. they could be worth looking into.
They have their own pros/cons too. The most obvious one for a water
heater application is that the whole house type would not shut off the
gas, which could be a problem if the tank were to spring a major leak
that could empty it. Also, being wireless, possibly battery operated
sensors, etc, not as reliable as the one location type you are

like faulty sensor turns off water and gas to tank, and after
bypassing system tank fails to relight for any reason, no doubt with
house guests coming for christmas, on christmas day.
such cascade failures do occur, I have had some happen here:(
on major leak drains tank but water is off???
my thought is tank is bad anyway, so what if burner comes on in a
empty tank? dont tanks have a high limit control?
whats the worst that could happen to a already leaky tank?
Incidently I had a water heater fail with house guests coming for
christmas. couldnt buy a heater anywhere finally found a plumber with
a tank in his truck:)
his tank install on christmas day was 1600 bucks:( we were lucky to
I NOW replace my water heater every 8 years or so, on my schedule DIY.
If the tank fails wont it flood the pilot light, it will go out and
nothing will happen. A pan under a tank and hose to drain always
works, its cheap. A whole house shutoff would be better and get an
insurance price reduction.
Our WH is in the basement, two rooms away from where the sump and pump
are. Installing a pan under an existing WH -- with solid copper
plumbing, not the now-recommended flexible connections -- would be
difficult, and arranging for it to drain into the sump would be difficult.
