Estimating what lengths you need is critical and some may speculate manpower too. For the last drill in April, did hose advancements with one-man, two-men, three-men operations when dealing with the 200' inch and three-quarter, 300' inch and three-quarter, and 200' duece and a half. This did a long stretch with 3" hose gated to inch and a half from the high-rise pack. Also identified other adapters and appliances to assist in hose advancment operations. Great drill I must say!
