Backflow Pressure Valves are use in places where perhaps Chemical maybe use in mixers washers ETC. If your premise's use any of this do not Eliminate BPV. if inspector comes around you could be penalized with very hefty fines, also you did not say is this well water or City water that makes big difference. For the well water yes you can use check valve but not if you use chemical down the line on the City supply defiantly not. Some area in USA are very strict on that.
