A simple photo from our 2008 seminar in Strong, Maine. Phillips Engine 4 (1000 gpm/3000 gal) was used to support dump site operations at the 2-hour drill. About an hour into the operation, the crews were able to round up several lengths of 3-inch suction hose from a couple rigs carrying portable pumps and they used that suction hose to bolster Engine 4's output ability. All of the suction hose had the same thread so all that was needed was a 2-1/2" double-male to make the connection to Engine 4's auxiliary intake. The valved intake allowed the driver to bring on the additional intake flow without shutting down operations.
The additional suction line on the driver's side allowed the 1000 gpm pumper to improve its output. The operator of the pumper was already drafting from the officer side suction inlet prior to the auxiliary intake being brought on line.
