The Fill-Thief bolts on the inlet of the Hale Master Intake Valve (MIV) and makes midship pump water supply management easy. The Fill-Thief is an accessory built specifically for users purchasing a midship pump and compressed air foam system combination. When a large diameter supply hose (LDH) is connected to the Fill-Thief inlet and the MIV is in the “closed” position, the incoming water is directed to a direct booster tank fill valve. This direct booster tank fill can either be a “manual” valve arrangement or a Hale “AutoFill” automatic direct booster tank fill valve assembly. The benefit of the Fill-Thief is that only one LDH line need be connected to feed both the direct booster tank fill valve, and/or, when the MIV is opened, the midship fire pump
