Every year in the spring, members of the El Dorado Fire and Rescue Service take the time to pressure test all of its supply (5-inch) and attack (various smaller sizes) hoses. Hoses are attached to a pump and pressurized to a prescribed pressure. Hoses with leaks are either repaired or retired. This process helps guarantee that the EFRS will be able to deliver water without problems to a fire when it is needed.
