Orbit is a reliable name in residential irrigation, and the 57065 valve tackles a specific problem most homeowners don’t think about until it’s too late: backflow. This 3/4-inch brass model uses an atmospheric vacuum breaker to prevent contaminated water from siphoning back into your home’s supply. It’s a simple safety measure that code requires in many areas, and brass construction means it won’t crack or warp under direct sun like plastic alternatives often do.

The inline forward flow design keeps water moving efficiently through the valve without pressure drops that can starve sprinkler heads at the end of a zone. The flow control knob lets you dial back the output manually, which is useful when you’re watering a sloped lawn or a narrow flower bed where overspray is a problem. At 4 x 6 x 7 inches, it fits standard valve boxes without cramping, and the 3/4-inch inlet threads match common PVC and poly pipe fittings. Installation is straightforward if you’re comfortable with basic plumbing—just cut in-line and glue or thread the connections.

One honest note: anti-siphon valves must be installed at least six inches above the highest sprinkler head to work properly. That means you can’t bury this valve underground like a standard inline valve. It needs to sit above grade, so plan for a riser or mount it on a wall. It’s a small trade-off for the backflow prevention it provides.
