My new department is having me drill by advancing 150' of 1 3/4 while flowing out of a combi nozzle with 200gpm at around 100 psi at the tip. Once I get to around 125' out I struggle moving it at all any further while flowing. They are all saying I should be able to move it and that they can all do it. Am I missing something? They have had me do this kneeling, crouching and standing. Is this just pushing me to see how far I'll go or is this something I should be able to do relatively easily? Thanks. I am a brand new FF and on the older end of a new recruit.
