Data Sheet

According to NFPA 25, Standpipe and pressure-regulating valve (PRV) systems require 5-year, full-flow testing to ensure 100 PSI (or 65 PSI in older systems) at the hydraulically most remote outlets. Fire pumps must undergo weekly visual inspections and annual flow tests to verify performance, often using hose manifolds to achieve required capacities. PRVs should be tested independently of fire pump flow tests. Many jurisdictions need to read the residual pressure after the hose valve and the velocity pr½essure so it can be converted to GPM.

The NNI’s All in one testing kit has 2½” & 1½” NST InLine Pirot Kit with Dual Read PSI GPM colored Liquid filled Gauges, a 2½" Swivel NST 30* Aluminum Elbow, 2½" Female NST x 1½" Male NST Concentric Reducer, 1½" Gate VAlve withh Female Swivel x Male NST fittings with a 1½" PVC Basket diffuser. Dual read Gauge Calibration will be extra @$60.00 each unit. The Gauge selections for

• 1½” Pitot tube are 0-60 Psi-468GPM Gauge, 0-100Psi- 604GPM Gauge, 0-160Psi -764GPM Gauge, and
• 2½” Pitot tube are 0-60 Psi/1300GPM, 0 -100Psi/1680GPM , 0-160Psi/2120GPM
  

You may need to add optional 2½” NST Double Jacket Hose, a NNI Static Gauge and a 2½” Basket diffuser o be added to be a complete system for all the tests.

Standpipe & PRV Testing Requirements (NFPA 25)

• 5-Year Full Flow Test: Requires testing the most remote hose connections to verify design pressure and flow.
• Flow Rate: Typically 500 gpm for the top riser and 250 gpm for each additional riser, up to 1,000–1,250 gpm total.
  
• PRV Testing: Pressure-regulating valves must be tested in place (using a gauge on the inlet/outlet) or bench-tested to confirm they reduce pressure to required levels.
  
• Hydrostatic Test: New systems require a 2-hour hydrostatic test at 200 psi or 50 psi above maximum pressure.
