Are you sure it's 60 gpm?
Yep, it fills a 6 gallon bucket in about 5 seconds.
The problem with air pockets happened with my 3 pipes that are 1 1/4 inches in diameter. They run along the ground and have ups and downs over the rough terrain with a max flow of 12gpm each, so when I put in the 2" pipe last year I wanted to make sure I got max flow.
Also there's alot of air bubbles in the stream water cause of the rapid flow across the rocks.
A 300ft pipe run in below zero temps tends to harden the water.
