These hookups made with a single LDH lines are not getting the full capacity of the hydrant. You might be surprised as to what this can do for you. The more you flow, the lower the pressure gets. Thanks guys for all the advice, I really do appropriate the valuable input. Where can I get the right hose attachment? I would be curious to see what the difference in flow on Test 4 would have been if they were hooked to the Steamer connections instead of the aux.
It would have performed better being pumped from the hydrant.
Pumping From The Hydrant
We want to hook a power washer up to a fire hydrant to clean the side walks. The adapter on the left is a "rocker lug swivel" x Storz model, which has a variety of other uses. In most cases this will get the hydrant capacity. These popular LDH gate valves used on pumper intakes are still being manufactured today. This GPM rated pumper supplied two aerial streams, its wagon pipe and a portable deluge gun for a total of GPM.
