Hydrant Flow and Pressure Testing Kits
Note: Gauges supplied with our Test Kits are quality Liquid Filled Gauges but do not come from any manufacturer with individual certification. Certification insures accuracy and is necessary for certain types of testing. Certification is normally done on an annual basis. Certified Pressure gauge calibration is a process of comparing a gauge in at least 5 test points over the span to a known certified and traceable pressure measuring device. We can test and certify gauges with a calibration sticker and a N.I.S.T. (National Institute of Standards and Technology) calibration document for an additional charge of $39.50 each Gauge.

Pumper Hydrant T Diffuser & Static Pressure Test Kit
A traditional fire hydrant contains three outlets: two 2-1/2” NH (65 mm) side outlets and a single 4”(100mm) NH, 4-1/2”(115mm) NH or 5”(150 mm) Storz pumper outlet. The pumper outlet is the preferred choice for the fire department to connect and feed pumper trucks. This heavy duty Fabricated (Yellow) Swivel T Thrust Buster Diffuser is used for Flow Testing as well as to reduce the force of flowing water from fire hydrant to control soil erosion and to safely direct the flow pattern. The Thrust Buster diffuser adds an increased level of safety to the operator and surrounding property by eliminating the thrust associated with loose hoses that may lay on the ground. It is recommended for all field-testing or water main flushing operations in which unsecured hoses are used to direct water flow.

Features: 
  • Ideal for high flowing hydrants.
  • Flow through the Pumper ports 4″ NH 4-1/2″ NH, or 4” & 5″ STORZ connections.
  • Slow close 250Psi Hydrant Gate Valve with air bleeder is standard.
  • 4”, 4-1/2” NH & 5” Storz Diffusers come with a 4” Dial Liquid Filled Dual read Gauge in range 0-60Psi/2958GPM..0-100 and 0-160Psi Gauges are available with a Flow Chart.

Application: The 2-1/2”, 4” & 4.5” Swivel T Thrust Buster diffusers have a a ball-bearing swivel adapter that will fit to a Hose. The 4” & 5” Storz T Thrust Buster diffusers have Storz adapter that will fit to a Hose also. A Pitot is positioned in the middle of the water flow to measure Pressure and flow from Hydrants. Replaceable pressure tube Pitot assembly with a quick connect Rubber covered Glycerine filled Pressure Gauge is used to perform flow tests.

Note: These kits come wit a wheeled case. The case will include Gate Valve, Static Cap, Two Gauges for Static and T diffuser, Remote T assembly and wrenches only. The Hose,& T diffuser body are packed separately.
