What Does The Common Wire Do On A Sprinkler System?

by | Last updated on January 24, 2024

, , , ,

The common wire is connected to, and shared by, all the

valves and completes the circuit back to the controller

. These wires carry a low voltage current, usually 24 volts AC, to energize the solenoid on the valve.

How many wires are in a sprinkler system?

Sprinkler wire is generally

one wire bundle with many strands of smaller 18-gauge wire

inside it. Wire Strands: These strands usually come in 3 to 8 wires but can go up to 12 or more. You will always need one extra wire in the bundle than the number of valves.

What color is the common wire on a sprinkler system?

The common wire is usually

white in color

and runs from your controller to your master cylinder and then to each of the other valves on your irrigation system in turn. If something happens to cut your common wire, then every valve after the cut will fail to turn on when activated.

What kind of wire is used for sprinkler systems?

Two basic types of wire are generally accepted and approved for use in irrigation systems.

Single conductor, solid core, 14- or 16-gauge insulated wire

is widely used.

How deep does sprinkler wire need to be?

The pipe is durable, UV resistant and completely waterproof when installed correctly. Like sprinkler pipes, you should bury the conduit

at least 6 inches deep

(sometimes more if municipal code requires). This will protect it from shovels and tillers.

How far can you run 18-gauge sprinkler wire?

There are many things to consider when sizing wire: voltage coming out of the controller, the solenoid draw, how many valves you’re trying to operate, quality of your wire splices, etc. For a rough rule of thumb, 18-gauge is good for

750 feet

, if you are operating one valve at a time.

Why are some sprinkler zones not working?

Although it sounds simple, if none of the zones are coming on, first

check to make sure the main valve for the system is open

. … Failing zones may also be caused by an electrical problem, which can manifest as a problem with the timer, the valve, the solenoid, or the wire. Frequently, a bad connection may be responsible.

Do sprinkler systems have wires?

When installing a sprinkler system, you will need to run

electrical wire

from the sprinkler controller to each sprinkler valve. … Use 16- or 14-gauge wire, which are larger, for longer distances.

Can I wire two sprinkler zones together?

Running multiple zones at once is usually not possible due water-pressure and flow limitations at residential properties. As with any standard irrigation controller,

you can wire multiple solenoids/valves to the same zone output if you want

.

Does sprinkler wire need to be buried?

Sprinkler wire can

generally be buried directly in the ground without conduit

and you don’t necessarily need to dig it below grade. A shallow burial is fine.

How far can you run 14 gauge sprinkler wire?

Valve Wire Sizing (Maximum One-Way Distance in Feet Between Controller and Valve) Ground Wire Size Control Wire (ft) 16 AWG 1040 2330 14

AWG


1210

3450
12 AWG 1350 4880

What is the difference between 18 5 and 18 7 sprinkler wire?

The Southwire 18/7 sprinkler wire is intended for direct burial applications with a rating of up to

30-Volt

. … 18/5 Sprinkler wire offers a sunlight and UV-resistant outdoor cable that is also suitable for burial in wet locations.

Can you run sprinkler wire above ground?

Running the wire above or

under ground is not the issue

. The most important concern is to make sure the wire won’t get cut or damaged by any means. Burying the wire is recommended, since it is hidden and not subject to damage from garden shears, nylon string trimmers, vehicle tires, foot traffic, etc.
