What is the purpose of water hammer arrester?

A water hammer arrester is a device designed to absorb the shock waves caused by the sudden stopping or changing of water flow in pipes, often referred to as "water hammer." This phenomenon can lead to loud banging noises and potentially damage Plumbing systems. By providing a cushion of air or gas, the arrester mitigates these shocks, ensuring smoother water flow and prolonging the life of pipes and fixtures. Overall, it enhances the comfort and durability of plumbing systems in residential and commercial settings.
