I was just curious to see the the regulator pressures at different settings, so I decided to hook up a couple of gauges and here are the results....
Lpr
At the flush setting my gauge read about 90 to 95 psi
So I counted the turns and this is what I got.
Turns from flush of lpr cap/ psi
Flush = 90 to 95 psi
1 turn = 85 psi
2 turns = 80 psi
3 turns = 70 psi
4 turns = 60 psi
5 turns = 50 psi
6 turns = 40 psi
Hpr
At flush the gauge reads 350psi
So I did the same and counted the turns...
Turns from flush of the bottom of the hpr/psi
Flush = 350psi
1 turn = 300psi
2 turns= 250psi
3 turns= 200psi
4 turns= 150psi
5 turns= 100psi
You can also turn it out past flush on the Hpr all the way up to 500psi.
