What is an Anti-Siphon Valve?
An anti-siphon valve, often referred to as a backflow preventer, is a crucial safety device in any sprinkler system. Its primary function is to prevent contaminated water from backflowing into your main water supply. This contamination could originate from various sources within your sprinkler system, including irrigation lines, sprinkler heads, or even the soil itself.
Imagine a scenario where your sprinkler system is turned off, and a vacuum is created within the lines. If there is no anti-siphon valve in place, this vacuum could draw contaminated water back into your main water supply, potentially causing health hazards. The anti-siphon valve acts as a barrier, preventing this backflow by ensuring that water flows only in one direction – from the main water supply to the sprinkler system.
Orbit anti-siphon valves are designed to effectively prevent this backflow, safeguarding your water supply and ensuring the health and safety of your family. They are essential components for any irrigation system, particularly those utilizing underground sprinklers, where the risk of contamination is higher.

Installation Guide
Installing an Orbit anti-siphon valve is a relatively straightforward process that can be done by most homeowners with basic plumbing skills. Here’s a step-by-step guide to ensure proper installation⁚
Gather Your Materials⁚ You’ll need the Orbit anti-siphon valve, pipe thread sealant tape (not pipe dope), appropriate fittings (adapters or nipples) for connecting to your sprinkler lines, and a wrench or adjustable pliers.
Prepare the Installation Site⁚ Turn off the water supply to your sprinkler system. Locate the desired installation point for the valve, making sure it’s accessible and in a location that allows for proper drainage.
Connect the Valve⁚ Apply thread sealant tape to the threads of the valve and the fitting you’ll be using to connect it to your sprinkler line. Tighten the connection securely using a wrench or adjustable pliers.
Test the Valve⁚ Once the valve is installed, turn the water supply back on and test for leaks. Check that the valve operates smoothly and that there are no signs of leaks at the connections.
Flush the System⁚ After testing, it’s a good idea to flush the sprinkler system to clear any debris or air that may have accumulated during the installation process.
It’s important to note that specific installation instructions may vary depending on the model of Orbit anti-siphon valve you have. Always refer to the user manual that came with your valve for detailed instructions and any additional recommendations.
Choosing the Right Location
Selecting the ideal location for your Orbit anti-siphon valve is crucial for proper function and longevity. Consider these factors when deciding where to install your valve⁚
Accessibility⁚ Choose a location that allows easy access for maintenance, repairs, and testing. A readily accessible valve will simplify routine tasks like cleaning and inspection.
Drainage⁚ The valve should be installed in a location that allows water to drain away from the house. This is especially important to prevent water from freezing in the valve during winter months.
Proximity to Sprinkler System⁚ Ideally, the valve should be positioned near the main sprinkler line to minimize the length of piping and potential for water pressure issues.
Code Compliance⁚ Consult local plumbing codes and regulations regarding the installation of anti-siphon valves. These codes may specify minimum distances from other fixtures or require specific installation methods.
Elevation⁚ For optimal performance, the valve should be installed at least 6 inches above the highest sprinkler head or elevated piping in the circuit. This ensures proper air ventilation and prevents siphoning.
By carefully considering these factors, you can ensure that your Orbit anti-siphon valve is installed in a location that maximizes its effectiveness and longevity.
Connecting the Valve
Connecting your Orbit anti-siphon valve to your sprinkler system requires careful attention to detail. Follow these steps to ensure a secure and leak-free connection⁚
Prepare the Pipes⁚ Clean the threads of the pipes that will be connected to the valve using a pipe thread cleaner. Ensure all debris and burrs are removed.
Apply Thread Sealant⁚ Apply a thin layer of thread seal tape to the pipe threads. Do not use pipe dope as it can clog the valve.
Connect the Valve⁚ Connect the valve to the main water supply line using the appropriate fittings. Ensure the valve is installed correctly, with the inlet side facing the main water supply and the outlet side facing the sprinkler line.
Tighten Connections⁚ Hand-tighten the connections initially. Then, use a wrench to tighten them further, but avoid overtightening. Overtightening can damage the valve or pipe threads.
Connect Sprinkler Lines⁚ Attach sprinkler lines to the valve outlet using an adapter or nipple. Ensure the connections are secure and leak-free.
Inspect for Leaks⁚ Once the valve is connected, inspect all connections for leaks. If any leaks are found, tighten the connections further or apply additional thread seal tape.
