What is the primary reason for installing an air chamber in a plumbing system?

The primary reason for installing an air chamber in a plumbing system is to prevent water hammer. Water hammer is a phenomenon that occurs when a quick change in water flow, such as when a faucet is turned off rapidly, creates a shockwave that can cause loud banging noises in the pipes. The air chamber serves as a cushion that absorbs the shock of the moving water, effectively dampening the impact and reducing the noise associated with water hammer.

This installation is crucial in maintaining the integrity of the plumbing system, as repeated water hammer can lead to pipe damage over time. The air chamber allows for a smoother transition of water flow, contributing to a quieter and more stable plumbing system.
