Water Pressue Regulator
There is a water pressure regulator to home
fixture. But the water pressure to the irrigation
system is too high. I talked with two
plumbers but they gave me different solutions.
I need your advice. Thanks for the help

1. relocate the current water pressure regulator before the house shut off
valve
2. Install another regulator after the irrigation shut off valve.
Where's the backflow preventer for the sprinkler system?
I use anti-siphon valve and there is no backflow
preventer for the sprinkler system.
If you have antisyphon valves (that's plural, as in one for each zone) then you should employ the flow controls to adjust pressures in each zone.
