As Wetboots stated, the backflow preventer should be the first piece of the sprinkler system to get water. All of the zone valves need to be downstream from the backflow preventer.

There isn't any part of a sprinkler system that is supposed to be located upstream of its backflow prevention. Is there something else connected to the water supply that figures into your question?

RPZ placement

I am designing a 12 valve sprinkler system utilizing an RPZ. Must the RPZ be placed upstream of all valves, or can it be located further downstream?
