The Purpose of the Common Wire in an Irrigation System

Every irrigation has a common wire that connects all of the solenoids together and in most cases it is a black wire, as this is the colour most commonly used.

The common wire is found in the ‘c’ terminal and is vital to the systems operation.

If a common wire gets cut then all of the solenoids that it connects together will be out of action.

Its usual to have one strand of multi core wire serving the front of a house and another strand serving the rear, so if you find that all of your rear solenoids have stopped working then chances are your common wire will have been cut or broken.

From there it just a matter of tracking it and repairing it.

Irrigation Controller Supply and Installation in Tapping

If your retic controller is dead, giving you trouble or just difficult to operate then give me a call!

I am based in Yanchep but service the northern suburbs. I carry a range of boxes onboard at all times but generally recommend the Hunter X Core for reliability, ease of use and value for money.

The Hunter has a two year warranty, a back up battery that will last 5-7 years and is remote control enabled (purchased separately).

It is also easy to use and comes with a lockable casing.

Prices as at March 2017 are $375 for a 4 station controller, $385.00 for a 6 station and $415 for an 8 station. These prices include GST and I am a licensed electrician so you can rest assured the job will be done safely and competently.
