I live in a rural area in Texas. I am installing a 3 station system that will be expanded to 9 stations in the spring. My well feeds a pressure tank that has an operating pressure of 30-50 psi. What type of backflow device will be best in this scenario?
If you are on flat ground, a PVB is your best bet. You might have to bump up the pressure switch settings to 40/60 for more reliable sprinkler performance.
