We found a few photos from our 2011 LDH/Relay Pumping Seminar in Hyde Park, NY. We laid out about a mile of 5-inch hose and added in a pumper here and there using different appliances. The challenge at the location shown in the photos was the use of a traditional, LDH manifold and a pumper that did not have a high-flow discharge. The scenario was water already flowing with the manifold in place upon arrival of the pumper. Crews had to position the rig, shut down the flow, and connect in the pumper. They folks got everything laid out and made the changeover in just under 2-minutes. Not an ideal situation regarding the addition of a relay pumper...but it certainly worked!
