I believe he meant what is listed in the title of email: Pressure required on placard is greater than what is shown static gauge. On Thu, Sep 22, 2022 at 4:04 PM Prahl, Craig wrote: > Um, that’s not an unusual thing. Pretty standard. > > > > Craig Prahl | Jacobs | Group Lead/SME – Fire

[Sprinklerforum] Re: [EXTERNAL] Pressure on placard greater that static.

Todd, Then I would be very concerned. What this suggests to me is that the available water supply is not capable of delivering the pressure required. Now why it can't do so is worthy of investigating.  Some things which come immediately to mind are a completely or partially closed valve,

The pressure requirement on the placard is higher than the static pressure on the riser. Todd G Williams, PE Fire Protection Design/Consulting Stonington, CT 860-535-2080 (tel:860-535-2080) (ofc) 860-554-7054 (tel:860-554-7054) (fax) 860-608-4559

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. Taylor Schumacher From: Prahl, Craig Sent: Thursday,

[Sprinklerforum] Re: Pressure on placard greater that static.

Maybe I'm reading this incorrectly but the system demand or required pressure should be lees than the static. If the static were less then: 1.)Age of system? Has area of building's location experienced an increase in demand due to growth? 2.)Utility system fed from elevated tank?

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
