Rain Bird CP075 In-Line Automatic Sprinkler Valve – 3/4" Female Inlet/Outlet, Black

Overview

The Rain Bird CP075 In-Line Automatic Sprinkler Valve is a compact, residential to light commercial valve designed for below-ground installation. It offers reliable automatic control when paired with a standard 24-volt irrigation timer or controller, making it a practical choice for yard and garden irrigation projects.

Why homeowners and pros choose CP075

• Inline convenience: 3/4" female inlet and outlet fit common irrigation setups, simplifying retrofits and new installs.
• Below-ground durability: The valve is designed to be installed out of sight, reducing exposure to curious hands and weather.
• Manual control option: A built-in bleed screw lets you test and bleed the line during setup or service.

Key performance features

• Reverse-flow design: Helps minimize stress on the diaphragm and reduces the chance of unintended water discharge in certain failure modes.
• Energy-efficient solenoid: Encapsulated, low-power operation with a captured plunger for dependable cycling.
• Buna-N diaphragm: Delivers solid performance in challenging water conditions, including sediment-heavy supply lines.

Installation and maintenance guidance

Install the CP075 below ground in a valve box downstream from the main line. After mounting, always flush the system of dirt and debris manually using the external bleed screw before startup. The valve is compatible with various Rain Bird spray heads, rotors, and other irrigation devices, and it can be used with any standard 24V timer or controller.

Important note: In-Line valves do not by themselves prevent backflow. Use a backflow prevention device as required by local codes, such as a pressure vacuum breaker (PVB) or double-check valve. Always check your city codes to determine the required valve configurations for safe, code-compliant irrigation.

Real-world use cases

• Residential lawns needing automated, zone-by-zone irrigation with reliable valve cycling.
• Light commercial landscapes where underground installation keeps components protected and unobtrusive.
• retrofit projects where existing 3/4" irrigation lines benefit from a compact inline valve solution.

With Rain Bird’s legacy of water-efficient design, CP075 provides a practical option for consistent irrigation control while keeping setup and maintenance straightforward for both DIY enthusiasts and professionals.
