Our department has been converting over to 50psi smoothbore nozzles from 100 psi automatic nozzles. We like the flow rates and lower pressures. We're having problems with our hose kinking when turning the tip and at the connection to the crosslay. I have photos of the hose kinked at the crosslay connection with the discharge gauge for that line in view and reading 140 - 150 psi. Is it the hose? Anyone else have any thoughts?
