Pull a dry 200+ft hose line (1 3/4" or 2 1/2" for increased difficulty)
Charge it, fully extended
Advance all 200 charged feet back and forth from fully extended to the pump panel 3 times
(Extend-charge. Pull nozzle and entire line past pump panel. Pull nozzle and line back to fully extended area- three times)
Vary the terrain for difficulty or increase hose size
