Description

18-Gauge Direct Burial Wire for Multi-Valve Irrigation Systems

This 7 Strand Direct Burial Wire is the essential link between your irrigation timer and your valves. Each cable contains seven individual 18-gauge strands — six are used to wire up to six separate valves, while the seventh acts as the shared common wire back to your electronic AC controller. It's rated for direct underground burial, so there's no need for conduit when routing wire from your controller to each electronic irrigation valve.

Available in 100', 250', and 500' lengths to match the size of your yard or garden layout. Pair it with waterproof wire connectors at every splice to keep connections protected from moisture and soil contact for the long haul.

Why Choose This Direct Burial Wire?
  • Controls Up to 6 Valves: One run of cable wires an entire multi-zone system back to a single controller.
  • Built-In Common Wire: The 7th strand is dedicated as the common, simplifying your wiring layout.
  • Rated for Direct Burial: Designed to be buried directly underground alongside your mainline tubing — no conduit required.
  • Multiple Length Options: Sold in 100', 250', and 500' spools to fit yards and gardens of any size.
  • Color-Coded Strands: Individual strands make it easy to track which wire connects to which valve and zone.

How to Install Your Valve Wire

Wire your valves to your controller in four simple steps.

Step 1: Plan Your Wire Run
Map the path from your controller location to each valve or manifold, allowing extra slack at both ends for connections and future adjustments.

Step 2: Connect Each Valve
Strip the end of one colored strand and connect it to a lead wire on each valve solenoid. Use a waterproof wire connector to seal every splice.

Step 3: Wire the Common
Connect the remaining lead wire from each valve solenoid to the single common (7th) strand, then run that strand back to the common terminal on your controller.

Step 4: Bury and Protect
Once connections are tested and confirmed working, bury the wire run alongside your mainline tubing. Housing connections inside a valve box makes future troubleshooting much easier.

Frequently Asked Questions

How many valves can this wire run?
This cable contains 7 individual strands, allowing you to wire up to 6 separate valves back to a single controller.

The 7th strand is reserved as the shared common wire that completes the circuit for every valve on the run.

Can I bury this wire directly in the ground?
Yes, this wire is rated for direct burial, so it can be placed underground without conduit.

For easiest future access, run it alongside your mainline tubing and route connections through a valve box rather than burying splices loose in the soil.

What length of wire do I need?
This wire is available in 100', 250', and 500' lengths, so the right choice depends on the distance between your controller and your farthest valve.

Always measure your planned route and add extra length for slack at connection points before choosing a spool size.

Do I need anything else to complete my wiring?
Yes, you'll need waterproof wire connectors at every splice point to protect connections from moisture and soil contact.

A valve box is also recommended to house wire connections and protect valves from the elements and accidental damage.

✔ Compatibility Check

Please note the requirements for this component:

  • Valve Capacity: Wires up to 6 valves per run. For systems with more than 6 zones, you will need an additional wire run or a higher-strand-count cable.
  • Bare Wire Only: This is wire only — it does not include wire connectors, a controller, or valves, which are sold separately.

Complete Your System

Make sure your wiring run is fully equipped with these recommended products:

  • Wire Connectors: Seal every splice between this wire and your valve solenoids to keep connections waterproof.
  • Electronic (AC) Valves: Pair this wire with reliable electric valves to automate each zone of your system.
  • Electronic (AC) Timers: Connect the common and zone wires to a multi-station controller for fully automated scheduling.
  • Valve Boxes: Protect your wire connections and valves from dirt, weather, and accidental damage.
