What is an Irrigation Master Valve?


Irrigation System Supplies Guide


When consider installing irrigation system, you might want to consider a master valve. A master valve is an electric valve installed at the supply point which controls water flow into the main piping system. When this valve is closed water will not be supplied to the irrigation system.

A master valve will greatly reduce any water loss due to a leaky station valve because the leaky station valve can only leak while the master valve is providing pressure to the system. Also, if you damage the irrigation main line, a master valve will control water loss so the main can be repaired without shutting off the water supply.

A master electric valve is typically the same type of valve as you would use for your station valves, but rather than being installed downstream from your main line and connected to a station output in your controller it is installed upstream at the front of the main line and connected to the “master” or “pump” connection in your controller. Not all controllers support a mater valve or pump- be sure to check the features before buying a controller.

  1. Awesome blog you have here but I was wondering if you knew of any forums that cover the same topics talked about in this article? I’d really like to be a part of community where I can get comments from other knowledgeable people that share the same interest. If you have any suggestions, please let me know. Thanks!

  2. Water flow stops at the master valve any helpful tips to correct.? ( I was told initially there was a problem with the main water valve into the system (replaced old one: was working after inspections)
