I've read about a mechanical shut off valve that can be used on any pipe.
Normally flow is restricted to a given amount by the appliance or faucet
being used, whereas with a broken pipe it gushes out at a faster rate. When
the safe rate is exceeded it closes the valve and requires a manual reset.
No power needed. I've heard this type of valve is required on some gas
lines. I'll look for more information.

A long time ago i saw reference to these things. Some sort of box

I should have read the copy more thoroughly. That load current sensing
type also uses a floor mounted moisture sensor for "belt and suspenders"
safety. As they say in the copy:

"The IntelliFlow'sT automatic operation and
floor mounted leak sensor protect against catastrophic water damage
should a washing machine inlet hose burst while the machine is in use."

I guess that floor sensor also helps out if the leak comes from the
machine's innards, and not from a leaking or burst hose.

Case closed...


Thanks for all the information. The only reason i mentioned the
current flow version was because that was the only one i was aware
off. The floor leak sensor idea sounds like a better idea overall.

Now to attempt to find a local (canadian) source.

Thanks again.
