How to Wire an Anti-Siphon Valve for Your Irrigation System: A Step-by-Step Guide

If you're installing an anti-siphon valve in your irrigation system, you may be wondering how to properly wire it. Wiring an anti-siphon valve can seem intimidating, but it's actually a straightforward process that requires a few basic tools and some electrical knowledge.

We'll guide you through the steps of wiring an anti-siphon valve in your irrigation system.

Materials Needed:

  • Anti-siphon valve
  • Wire cutters/strippers
  • Waterproof wire connectors
  • Electrical tape
  • Solenoid valve wires
  • Control wires

Step-by-Step Guide:

  1. Turn off the water supply to the irrigation system before installing the anti-siphon valve.

  2. Determine the location for the anti-siphon valve and ensure that it is at least 6 inches above the highest sprinkler head in the zone it will be serving.

  3. Connect the main water supply line to the inlet of the anti-siphon valve using a threaded fitting.

  4. Connect the outlet side of the anti-siphon valve to the PVC pipe that leads to the irrigation zone using a PVC coupling.

  5. Connect the control wires to the solenoid valve wires using waterproof wire connectors. Connect the white wire from the solenoid valve to the common wire in the control box, and connect the other colored wire from the solenoid valve to the appropriate zone wire in the control box.

  6. Run the wires from the control box to the anti-siphon valve and connect them to the corresponding wires on the solenoid valve.

  7. Use wire cutters to trim any excess wire length and strip about 1/2 inch of insulation from the end of each wire.

  8. Twist the stripped ends of the wires together and secure them with waterproof wire connectors.

  9. Wrap each wire connector with electrical tape to ensure a secure and waterproof connection.

  10. Turn on the water supply and test the anti-siphon valve to ensure that it is working correctly.

Wiring an anti-siphon valve is an important step in installing an irrigation system. With the right tools and a bit of electrical knowledge, you can wire your valve safely and efficiently. Follow the steps outlined in this article to wire your anti-siphon valve correctly and ensure that your irrigation system is working effectively.
