The Working Fire Fixed Flow Nozzle with Pressure Relief wins again. During Gated Wye Operations and one line is shut down, the GPM increase is 20 GPM greater and nozzle reaction is 10 lbs. less than a standard fixed flow nozzle.

Here's the setup for today's nozzle comparison. We have 200 feet of two and a half inch hose line integrated with a two and a half inch Sho-flow meter so we can see our flow rates in real time. At the end of the two and a half inch hose line we have a gated Wye appliance. Each side of the gated Wye has a hundred feet of inch and three quarter hose, one line has a Working Fire Fixed Flow nozzle with pressure relief and the other line has a standard 150 at 75 fixed flow nozzle. So collectively we're flowing a combined 300 gallons per minute, 150 gpm out of each hose line.

Now when I shut down the standard fixed flow nozzle the flow increase of the Working Fire goes from 150 gpm to about 190 gpm with about 80 pounds of reaction force. Now we'll do the opposite, back to flowing 150 out of each line. We're gonna shut down the Working Fire, when I shut down the Working Fire the flow increase of the standard fixed flow goes from 150 to only about 175, and the reaction force goes up to about 90 pounds.


The Working Fire fixed flow nozzle with pressure relief wins again during gated Wye operations. When one line is shut down the Working Fire gpm increase is about 20 gpm more and the reaction force is about 10 pounds less than a standard fixed flow nozzle. Experience the new standard in fixed flow nozzles. See the difference, feel the difference, schedule a time to flow the working fire nozzle today at theworkingfire.com.
