Pressure reducers

My father has too much pressure in his lawn sprinkler measured at the vacuum break at 95psi. We want to install a pressure reducer but are unsure if water will flow backwards through the reducer.

Living in Colorado, the sprinkler needs to be completely drained in the fall. There is no room between the main sprinkler shutoff and the drain so the pressure reducer must be installed downstream of the drain. I'm unable to determine if the pressure reducer will allow water to drain back, if not we need to install a second drain downstream of the reducer. Any help is appreciated.

Move your irrigation shutoff or vacuum breaker. If your house indeed has this much PSI, you might want to reduce the pressure for the entire house. 95 PSI is too much for a lot of common household items. I wouldn't want to wash my hands in a sink with that much pressure or take a shower that would leave marks in my back.

If you can take a picture it would be easier to pinpoint where to install this.
