Interesting
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.
Thumbs up 👍
