is a master valve and flow meter required for irrigation systems
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.
