Back when I first started doing calculations I was told that when calculating sprinklers that I need to strive for a minimum of 14 psi regardless of required flow. We often do jobs in smaller towns with not so robust water flow figures. When possible I will reduce the K factor to bring my pressures up or manipulate pipe sizes as much as feasible to get as close to 14 psi as I can.
My question is- Is 14 psi a requirement or is it acceptable have pressures lower than that?
