Step-by-step explanation:
There are plumbing requirements for all sinks. True. Plumbing requirements for sinks include the need for air-filled tubes near water faucets. These tubes, often called air chambers or water hammer arrestors, help prevent the occurrence of water hammer, which is a phenomenon that can occur when the flow of water is suddenly stopped or changed direction. The air-filled tubes act as cushioning devices, absorbing the pressure spikes and preventing the pipes from rattling or vibrating.
