ABSTRACT:
A method of stopping excessive leakage from sprinkler heads of a liquid piping network. Firstly, providing a backflow inducer housing divided by a flexible diaphragm into a first compartment on a first side of the diaphragm and a second compartment on a second side of the diaphragm. The relative volume of the first compartment and the second compartment change with the positioning of the diaphragm. A spring is provided in the first compartment to bias the diaphragm toward a backflow inducing position in which the volume of the first compartment is larger than the volume of the second compartment. Secondly, connecting a first inlet/outlet of the housing to a liquid piping network. Thirdly, connecting a second inlet/outlet of the housing to a source of pressurized working fluid. The diaphragm is moved by the pressurized working fluid toward an operational position in which the volume of the second compartment is larger than the volume of the first compartment. Fourthly, providing controls to exhaust the second compartment of the backflow inducer housing simultaneously with the termination of spraying. The diaphragm is rapidly moved to the backflow inducing position thereby drawing sufficient liquid from the liquid piping system to prevent excessive leakage of the sprinkler heads.
