I talk a lot about "pumping the hydrant" because I was brought up to do it in the PG/DCFD area and because I have repeatedly seen it pay off on the fireground. It is essentially remnants of the old school "wagon & pumper" 2-piece engine company, but it still has ample benefits today. The primary benefits are: 💧 The ability to increase pressure/GPM to the attack engine if necessary. You can often increase your flow by 50% or more. How much, specifically, is dependent on your water system. 🚒 It
