Inquiry (采购产品): Shut off valves I need a valve that will shut the water flow off on an underground tank when the water level reached a perscribed level.The tank is used for holding 8.ooo gallons of water for fire protection for a rural fire department. The water is supplied by an variable speed pump in a nearby well. **** Hidden Message ***** Mike Slater 49684 Company: Mansfield & Associates, Inc.
