Todd, if I’m reading this correctly that means you have a safety margin on your 
system. That’s a good thing that your system provides more pressure than is 
required.

It would be cause for concern if the gauge showed less than required.

Um, that’s not an unusual thing.  Pretty standard.

Subject: [EXTERNAL] [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?
