in your main, hydrant opened for fire-fighting purposes, or just natural dip water pressure coming into your home, the water under higher pressure in your plumbing pipes will naturally flow backward to equalize the pressure difference.

Step Sand all portions of the piping that will connect, including the inside of the couplings on the preventer and the outside of PVC pipes.
By water from the supply side and should prevent sudden spikes in pressure on the opposite end of the cross, The differential is designed to be overcome-connection..
which would be caused by backflow, there's also pressure relief valve that will empty the chamber until the pressure on the receiving end of the cross-connection has subsided..
The pressure relief valve is designed to eliminate in the plumbing pipes during backflow, it will spit water out.
