Big Boy Hose Monster®
 
Flow from your hydrant pumper port - 4", 4-½", or 5" Storz!

The BigBoy Hose Monster™ is used for fire flow testing of hydrants, water main flushing, and fire pump testing from connections 4 Inch or larger. The BigBoy Hose Monster incorporates the patented Pitotless Nozzle™ so rocks and flushing debris pass through without causing pitot damage.

FM-approved, it measures water flow-rates from 750 to 2,700 GPM. The BigBoy Hose Monster body is made from Polypropylene and the Pitotless Nozzle is made from precision-machined aluminum.

A 5' or 10' length of hose usually positions the Hose Monster in the street gutter. Any length hose can be used and does not affect the accuracy of flow rate readings.


The Hose Monster is not recommended to be connected directly to the hydrant.

 

STAY DRY WITH REMOTE READER!
(12 foot length shown)
 
  • Perfect for Fire Flow Testing of Hydrants or Water Main Flushing
  • Read your GPM flow-rate directly on the gauge face while flowing
  • Uses the patented Pitotless Nozzle so you'll never have to change out a pitot because it got damaged by flowing debris
  • Weighs only 13 pounds yet handles high flow hydrants up to 2,700 GPM
  • Flow from your hydrant pumper port - 4", 4-½", or 5" Storz
 
TAKING FLOW READINGS

The BigBoy GPM Gauge is calibrated to read flow-rate directly from the gauge face. No conversion chart is necessary. If you use another pressure gauge instead of the BigBoy GPM Gauge the BigBoy Hose Monster flow chart must be used to convert from PSI to GPM. A 0-60 psi gauge is the most suitable range. A Big Boy flow chart is provided with the original purchase and additional copies are available here.
