In the well-read October 2007 Fire Engineering Article “How Kinks Affect Your Fire Attack System” Jerry Knapp along with Tim Pillsworth, Christopher Flatley, and Doug Leihbacher go into great detail how kinks affect your fire flows.

In this episode, we have recreated this same work in the article and the results may surprise you. We found that there is no pre-conceived rule of thumb for how kinks affect your system, rather testing with your own hose and nozzles is the best way to know how your kinks will have an effect.
