Flowing Water Test: Before we pressure test the hose we need to flow water through it until all the air is pushed out and we have a good flow of water. Then we shut the nozzle off and pressure test the hose to 250 psi for 5 minutes to ensure it does not burst. This is very important to ensure we don't have a hose burst during a fire. | Dave Shook & Wayne Smith Cleaning Hose. Each year when we pressure test the hose we also clean it by running it through the hose wash seen here. We also wash our hose after we use it to keep the dirt and grime off of it after fires. |
