Priming A FlowZone Sprayer

Tools Needed: garden hose (or something similar), fresh water

Sometimes, although rare, after a long period of storage, the sprayer's diaphragm pump may become non-responsive. Priming the system correctly is critical to restoring functionality. One of the most effective methods is forcing water into the pump through the inlet filter inside the tank.
