Taylor I had a similar issue come up on a job I was working on and I showed the Engineer the specs on a flow switch, they only detect flow of 10GPM or more. So not really a leak detector. They only notify on a major flow of water which if you have more than 10GPM flowing in a garage people will notice.

I have a long section of pipe between my backflow preventer and the suction flange of my pump that a plan reviewer wants supervised. I get the concern, but I have concerns with the paddle in the suction piping. Any thoughts or experiences are greatly appreciated. Taylor Schumacher ET
