I've got a question for those of you who use the "Cleveland Load" aka the "Pro Load" aka the "Metro Load" aka the "Roundabout Load" for your preconnects.
We have used this load with success for several years and have implemented it pretty much system wide at the metro sized FD for which I work.
Recently we have discovered flaws in the load, and I can only attribute it to the hose we as a department have recently purchased.
During training and flow tests to confirm anectodal evidence from training we have noticed a marked decrease in flow while using a particular type of lightweight/"low friction loss" 1 3/4" hose deployed from the above mentioned load. This decrease seems to stem from a "kink" that occurs during deployment when the coil is paying out into the flat configuration (basically at the end of the pull of each coil as it uncoils).
This "kink" seems more extreme with this particular brand of hose, so much so that it impedes flow significantly. This scenario bore itself out during a recent interior attack when a line pumped to 150 on an 1 3/4" with a smooth bore went limp and did not respond to pressure increases.
Has anyone out there using this load experienced similar issues with this load and light weight attack line combination?
Thank you for your time.
