Boy, there are many of us who have learned this one the hard way, even despite due diligence. George L. Church, Jr., CET Rowe Sprinkler Systems, Inc.

This was the plan for a project we had about three years ago where this very requirement was in place. The FD knew of the water purveyor's 20 psi requirement and had a contingency plan for areas of the municipality where the water supply was weak. This is typically not a surprise to the FD and the water dept. The surprise comes to those of us on the outside who aren't familiar with the local rules and regulations. Craig L.

None that I know would stop.

I suppose the water co wouldn't want the pressure to go below 20, but it flies in the face of all we stand for to have a shut-off inserted for stopping the operation of the sprinkler system if the supply pressure is below 20 PSI. You could save a lot of first floor lives with 20 PSI. George L. Church, Jr., CET Rowe Sprinkler Systems, Inc.

Can you give me more details on this?

Here is a quote from a spec that I have received. "The fire protection systems shall not be designed to operate if the residual pressure of the existing water service falls to 20 psi or lower at design flow requirements."
