Not to drift too far off topic, but just how often do the public utilities experience power outages lasting for a day or two? Here in the desert southwest we don’t see outages more than a few hours and even those are rare.

I've seen 13-D, and 13-R, operate a number of times well outside original design criteria, and alway successfully. By successful, living spaces stayed survivable. There may have been considerable fire outside the unit, and attic may have been fully involved. I wonder where water source is municipal, effectively unlimited, source we should just accept that some times the clothes washer or lawn sprinklers are on. Are a flow switch and 120V alarm, installed, cheaper than $600?

When the grid is down I still enjoy the use of modern plumbing supplied by a municipal water system. Take it away every time power is off for a day or two and solenoid valve would be disabled or removed by owners. Mechanical valve is best for a reason.

I assume you’re designing to an undersized meter. Either get relief from the water agency to add the 5 GPM to the intermittent flow rate of the sprinklers (as opposed to the continuous flow for which the meter is rated) or have the owner bite the bullet and buy a larger meter? I’m sure there are people who will disagree with me, but relying on an electrical device that is not subject to regular exercise or inspection isn’t my idea of reliable.

I checked out the RSV-1 from Tyco and the list price is $1,000.00. I about fell out of my chair. It is on the sprinkler riser with a branch off to the domestic. When fire sprinklers flow the pressure change causes the valve to shut off the domestic. It is non-electric, maybe that is why it is so expensive. It has been years but the one I have seen was a simple solenoid valve that is attached to the domestic water and simply closes when it receives an electric current from the activated flow switch. HELP anybody!

This is so I can eliminate the 5 gpm from the 13D calculations.
