Well it was not agood idea and they are junk.
Replace it or put up with it's false trips forever.
These was a brilliant idea of a marketing genius who subscribed to the build it and it will sell theory of marketing.
The engineers wondered why anyone would need one as it is a valve to save the day if a "no-burst" hose ever bursts but went on and accomplished the task they were assigned.
To reset it with the valve off, loosen the connection at the stop valve to bleed off the pressure then retighten the connection and turn on the water. Slowly! Don't be surprised if you have to do this often.
Personally I'd replace it!
Hi Redwood,
I actually bought 2 of these for my washing machine supplies a few months ago, and I must be very, very lucky! I've turned the water off a few times, bled some lines, and of course air travels through the pipes to places untold, right?
So I've heard my toilets 'explode' when air hits their location upon turning the water on, but so far it hasn't affected the washing machine. Probably because of its location at the lowest point in the plumbing chain?
In any case, I hear ya............
