b) check valve
c) flow regulator
d) safety switch

Answer 1

A check valve is installed on the discharge side of the leading pump station to prevent reverse water flow.

Step-by-step explanation:

A check valve is installed on the discharge side of the leading pump station to prevent reverse water flow. When the pump is turned off, the check valve closes automatically, preventing water from flowing back through the pump. It ensures that the water only flows in one direction, which is from the pump to the rest of the system. This helps maintain the desired flow direction and prevents issues such as water hammer and potential damage to the pump.
