[Sprinklerforum] Pressure on placard greater that static.

I have run into a couple of situations where the required pressure as shown on the system placard is less than the static pressure on the riser. I found another one today during a survey. If others are finding this, how do they handle it? Todd G Williams, PE Fire Protection
