Backyard Drainage Solutions That Actually Work in 2026
Jul 21st 2026
This 13 Strand Direct Burial Wire is the backbone connection between your irrigation timer and your valves, letting you wire up to 12 individual valves back to a single controller. One of the thirteen conductors is reserved as the shared common wire, while the remaining twelve strands each control a dedicated valve or zone. Built as 18-gauge wire and designed for direct burial, it pairs with any irrigation timer and irrigation valve setup that needs multi-zone control.
Available in 100', 250', and 500' lengths to match the distance between your controller and the farthest valve in your system, this wire keeps every zone wired back to one central timer. Finish each connection with a waterproof wire connector to protect splices from moisture and corrosion over time.

Connect your valves to your timer in a few straightforward steps.
Step 1: Plan Your Wire Run
Measure the distance from your timer location to the farthest valve to confirm which length (100', 250', or 500') will reach every zone with enough slack for connections.
Step 2: Trench and Lay the Wire
Dig a trench from the timer location to each valve and lay the wire bundle along the run, leaving extra slack at each valve box for splicing.
Step 3: Connect Each Valve
At each valve, strip and splice one dedicated strand to the valve's solenoid wire, and connect every valve's remaining solenoid lead to the shared common strand. Secure every splice with a waterproof wire connector.
Step 4: Wire the Timer
At the controller end, connect each dedicated strand to its corresponding numbered station terminal, and connect the common strand to the timer's common terminal.
How many valves can this wire control?
This 13-strand wire can run up to 12 separate valves from one timer.
Twelve of the strands act as individual station wires, one per valve, and the thirteenth strand is the shared common wire that connects back to every valve's solenoid.
Can I bury this wire directly in the ground?
Yes, this wire is rated for direct burial.
For added long-term protection, especially under driveways, walkways, or other hardscape, running the wire through a separate conduit sleeve is a good precaution.
What length should I buy?
Choose a length based on the distance from your timer to the farthest valve in your system, plus extra slack for splicing at each connection point.
This wire is available in 100', 250', and 500' lengths to accommodate small yards up to larger multi-zone properties.
Do I need a wire connector at every splice?
Yes, every wire splice should be sealed with a waterproof wire connector.
Buried or valve-box splices are constantly exposed to moisture, and an unsealed connection is one of the most common causes of valve failure or a station that won't respond to the timer.
