Step 1: Close the discharge valve
The first step is to close the discharge valve of the pump to prevent any further flow of the fluid. This closure will stop any back-flow of the liquid and secure the system from leaks and spills.
Step 2: Slow down the motor or prime mover
Step 3: Stop the motor or prime mover
Step 4: Open the vent valve
The fourth step is to open the vent valve located near the discharge valve. This valve allows any remaining fluid in the chamber to escape. An open vent valve prevents the creation of a vacuum that could impede the next start-up of the pump.
Step 5: Drain the pump
Step 6: Inspect the pump
