Question

In order to reduce the effect of water hammer on pump discharge and suction lines, these lines are often equipped with________ a) corrugated expansion joints b) strainers c) bypass valves d) globe valves e) air chambers

Answer 1

Air chambers are used in plumbing near water faucets to reduce water hammer by absorbing pressure surges. They work by trapping a pocket of air that compresses when water flow is abruptly stopped.

Air chambers are commonly used in plumbing near water faucets to help reduce water hammer. When water is flowing through the pipes and suddenly stops, it can create a surge of pressure known as water hammer. The air chamber acts as a cushion, absorbing the pressure surge and preventing damage to the pipes and fixtures. It works by trapping a pocket of air that compresses when the water flow is abruptly stopped, reducing the force of the pressure wave.
