RE: FDC & Pump Suction

Is cap it and put one on the building an option? Generally that's what we'd do in that scenario as there isn't much else you can safely do because of the compound pressure increase potential with a fire pump. Presumably you have to put a test header somewhere, just add an FDC as well? Of

The requirement is from NFPA 13, not from NFPA 20. Here is the text from NFPA 13-2013: 8.17.2.4.8 Fire department connections shall not be connected on the suction side of fire pumps. Larry Keeping From: Sprinklerforum [mailto:sprinklerforum-boun...@lists.firesprinkler.org] On Behalf Of

RE: FDC & Pump

The pump will still boost its inlet pressure. If you use the FDC to boost the inlet pressure to 175, then the pump will discharge 175 + pump pressure. Could be too much. Matt From: Sprinklerforum [mailto:sprinklerforum-boun...@lists.firesprinkler.org] On Behalf Of Jamie Seidl Sent: Wednesday,

Re: FDC pump in circle with hydrant on underground

For fire protection one of the most sought and least important measures is "arrival time of first unit". A much better time measure is agent (water) first applied, and when enough of that agent is applied to stop growth. It takes time to stretch lines, and apply water. Let's avoid a very long

Lol. I was thinking about the graphic Ken P posted yesterday, lower left with the gate, check, gate, and imagining the check being held open like it wasn't there, or only 85% there or whatever, and a Fire Dept. person wanting two checks in case one of them got held open by a rock. Your hydraulic

Is there a key operated gate upstream of the FDC they plan on closing once they get set up, to 'check' the circuit? I have heard some concearn by FP people about rocks holding check valves open and creating the situation you describe. Brad On Feb 7, 2017 1:57 PM, "Allan Seidel"
