4″ Supply Hose – Liner Delamination

GotBigWater – We recently had the opportunity to observe a flow test of 4-inch LDH. During the test, flow results were much less than expected. 

While disconnecting the supply lines, several sections of the 4-inch LDH were found with a delaminated inner liner. Many of the sections had significant flow occlusion due to the delamination. Thus, more reinforcement about the need for annual hose testing and visually inspecting all fire hose both inside and out. The hose shown in the video passed the annual hose test in 2016, and in previous years.
