Well done! Maximizing rural water supply is almost an art form. When you realize the pump intake manifold is a hollow metal box then intakes can become discharges. That hard suction line is either an intake or a discharge. Now try filling another drop tank by siphoning through the intake manifold. Keep in mind also that you can receive water from multiple vehicles through multiple ports in the intake manifold. Have you ever tried drafting from the drop tank while also receiving from the tender? If say you wanted the deck gun at 1,250gpm for a quick knock down but the tender was only supplying 500 gpm? Not possible without collapsing the tender’s hose? It’s possible, almost easy ;-)

We are able to receive and pump at the same time. We just upgrade our main engine to 4"LDH, 1150' with STORZ fittings. We have a triple Siamese that we can hook up to 3 tankers at a time to. We run water back and forth to extra fold a tanks with jet lifts.

A problem we did run into on our hard suction with STORZ fittings is that you need dual suction gaskets on them or they will suck air. Our Department has 2 tankers, a 2000gal and a 4000 gal. We also have available another department with 2 2000 gal. tankers and several independent water haulers with 4000 gallon trucks.

Town of Colonie doesn't know what tanker operations is all about hahaha. Hydrant infested town it is.
