Looking through some more photos...this time from our 2016 seminar in York County, Maine we found a couple good ones showing a pump operator overcoming not having a high-flow discharge...but needing to supply a 5-inch line. Nothing fancy to see here...just the use of a 2-1/2" x 2-1/2" x 5" clappered siamese to supply 1000 gpm through a 5-inch LDH line. The pumper was an older, 1250 gpm rig built on a commercial chassis and had no "high flow" discharges. The rig carries these short sections of 2-1/2-inch hose and the siamese for the sole purpose of being able to supply 5-inch LDH. It worked just fine that day and much better than just trying to connect the 5-inch to a 2-1/2-inch outlet using an adaptor. A good (and inexpensive) example of overcoming a flow problem with an older pumper.
