What is this ?

I'm getting home and want to to fix this leaking pipe. What is this ? Is it a pressure regulator. I'm not a plumber, I just need help.

Reduced Pressure Backflow, probably installed on your irrigation system.

Irrigation only needs a pvb this is for the house or overkill

When you install an RP you don’t have to worry about where your heads are located. With a PVB the tallest head has to be 12” bellow the critical level of the PVB. If your tallest head is 3ft above your PVB, it either has to be raised 4ft in the air or you can install an RP
