Abstract:
A system for controlling the flow of water through a water supply pipe into a building, said system comprising:a valve connectable to the water supply line, wherein said valve has a closed condition that is capable of stopping water flow through the water supply line and an open condition that permits water flow through the water supply line;a flow meter connectable to the water supply line, wherein said flow meter produces a water flow signal indicative of the volume of water flowing through the water supply line when connected to the water supply line;a systems controller having a first operations mode and a second operations mode, said systems controller being coupled to both said valve and said flow meter, wherein said systems controller reads said water flow signal from said flow meter and closes said valve at a first flow rate, when in said first operations mode, and closes said valve at a second flow rate, when in said second operations mode, and wherein said first flow rate and said second flow rate are different.
