Direct Burial Wire

The most common gauges for direct burial irrigation wire are 16 and 18 gauge. The gauge you choose depends on the length of the wire run and the number of valves being controlled. Typically, 16-gauge wire is used for longer distances or systems with multiple valves to ensure adequate power transmission.

Direct burial sprinkler wire is designed for underground use and should remain buried to protect it from environmental factors like UV rays and physical damage. For above-ground installations, consider using wire rated for outdoor exposure or protect it with conduit.

To install direct burial irrigation wire, run the wire from the controller to the valves, ensuring it is buried at least 6 to 12 inches below the ground. The wire’s robust thermoplastic sheath protects it from moisture and soil corrosion, ensuring long-term performance. Always avoid sharp bends and ensure there’s no tension on the wire during installation.

Make sure to use waterproof wire connectors for underground sprinkler wire. These connectors are typically filled with silicone to protect the splice from moisture. Avoid using standard indoor wire nuts or generic electrical tape alone. For the most reliable setup, ensure that the connectors are rated for direct burial and wet locations.

While you technically can use regular electrical wire to power sprinkler valves, it is highly discouraged. Irrigation control wire is usually the best choice because it’s designed for outdoor and underground use. Standard indoor electrical wire generally isn’t appropriate for direct burial or wet locations.

Yes, direct burial sprinkler wire is encased in a thermoplastic sheath that provides protection against moisture and harsh underground conditions. This ensures that the wire operates reliably, even in wet soil or areas prone to flooding.
