As a domain expert in fluid dynamics, I can explain the phenomenon of pipes making noise when water is turned on.
When water is turned on, it rushes through the pipes, creating a disturbance in the flow. This disturbance can be caused by several factors:
1. Water Hammer: This is a common cause of noise in pipes. It occurs when the water flow is suddenly stopped or changed direction, causing a pressure surge that can slam against the inside of the pipe walls, creating a loud knocking or banging sound.
2. Air Entrapment: If there's air trapped in the pipes, the water can force the air through the pipe, causing a gurgling or knocking noise.
3. Pressure Changes: Rapid changes in water pressure can also cause pipes to make noise. This can happen when multiple fixtures are used at once or when the main water supply is turned on or off.
4. Pipe Expansion and Contraction: As water flows through pipes, it can cause them to expand and contract, especially if the pipes are made of metal. This movement can create a humming or vibrating noise.
5. Loose Pipes: Pipes that are not securely fastened can vibrate more easily, amplifying any noise they make.
6. Water Flow Restrictions: If there's a partial blockage or a valve that's not fully open, it can cause the water to make noise as it tries to pass through the restriction.
7.
High Water Velocity: Fast-moving water can cause a whistling or whining noise, especially in narrower pipes.
To reduce noise, it's important to ensure that pipes are properly secured, that there are no air pockets in the system, and that any changes in water flow are gradual rather than sudden.

WATER pipes that bang, hammer or squeal are not only a nuisance, they may also be an indication of plumbing problems. One of the most common noises is a whistling that occurs when a water valve or faucet is turned on, or when a toilet tank is refilling after flushing.
