This project is a little more involved than I initially thought and I have some questions.
I believe I need to replace the backflow preventer in the picture with a reduced pressure backflow preventer. In addition, with my 95 psi incoming pressure, I will be adding a separate pressure reducer along with the flow meter and master valve.
My thinking is put the pressure reducer first, then the reduced pressure backflow preventer followed by the flowmeter and lastly the master control valve. Is this the proper order for these components?
Lastly, as shown in the picture, there is only 7 inches between the two risers coming out of the ground. Would it be ok to plumb the components in a “V” configuration (with the end of the V floating in air) or do I need to dig up the downstream riser and move it?
