Proper pump pressures for most 2 -inch hose layouts are relatively low, frequently much less than 100 psi. Train your pump operators thoroughly, and specifically train them to NOT over-pressurize this weapon. It can also be the difference between buildings saved or parking lots created. For example, one small pile of hose left unchecked equates to several kinks in the charged hose line. This makes advancement very difficult and leads to a reduced water delivery.
Some individuals advocate correcting kinks by adding pressure, a very dangerous practice.
Take the time necessary to stretch the line properly, the first time. Advancing the charged 2 -inch line can be a very demanding experience, but it can be done. Use the manpower you have appropriately to maximize their efficiency and effectiveness. Use the ground to counter nozzle reaction. The backup man can press the line down against the ground with his weight, allowing the nozzle man to direct the stream.
