UnderHill Fire Nozzle Shootout | Low Flow Full Throttle VS High Flow Full Throttle | Full Test!

In this video we test the Underhill fire nozzles head to head in a battle of the best 3/4" fire suppression home nozzle setup. In this test are the Underhill low flow full throttle nozzle, and the Underhill high flow full throttle nozzle. Both nozzles tested on 80psi of water with high flow 3/4'' ID hose and a high flow 3/4'' ball valve water spigot. These are both NECESSARY items in order to maintain adequate pressure and flow out of these forestry style nozzles.

Thumbs up 👍

So I have a question maybe you can help me with. I have a high flow ball value and 100ft 3/4 inch hose that at best flows approx 15 gpm at about 90 psi. I brought a high flow nozzle but it seems weak in the spray patterns almost like I dont have enough flow. I think I may have better luck with the low flow since it claims 12-19 gpm whereas the high flow claims 15-40 gpm. I noticed you were yielding approx 23 gpm so maybe the high flow benefits you more. Do you think a high flow helps if you can't provide more than 15 gpm? Only other option is buy both and test them. Thanks again

at 90PSI you should probably run a 1" high flow ball valve. Reason being is the internal diameter of the 1" ball valve is actually 3/4", exactly matching the diameter of the brass tubing that runs to your home. If you run a 1" high flow ball valve instead of the smaller one you likely have, you will increase your GPH output and be able to run the higher flow nozzle without a weak spray pattern. I note this because I used to run a 3/4" ball valve and had the same issue, jumped up to a 1" valve and I increased my GPH tremendously.

At 80 psi, I would be more worried about the pipes inside your house.
