What I meant was the Delta flow from the most demanding head was 1.25gpm.The actual flow from the head was 8.68gpm and the required flow was 7.43gpm which was a delta flow of 1.25gpm. My HydraCalc program refers to it as Delta Flow ( past experience I heard it being referred to as overage, would that be the correct term? I had a pressure of 170psi so my only concern was keeping the flow down for the meter size.
