A local volunteer fire department reached out about foam issues on one of their trucks. The foam system injects a small amount of foam concentrate into the water flow when needed by the firefighters to aid in extinguishing certain types of fires.
The issue with this truck was the foam pump was not turning on at all when requested and it was found the flow meter had failed, replaced this component and pump is now turning on with the foam controller.
This system works well, but the foam concentrate can be corrosive to components like the injector and it tends to stick open and slowly leak foam into the pump. Swapped out the injector and this issue was also corrected.
Every truck usually gets a quick check over for any visual problems and a couple of minor issues were noted and TFM will head back once the parts arrive, keeping this truck on active fire duty in the area.
