As a domain expert in fluid dynamics and engineering, I have extensive experience in dealing with various issues related to water systems, including the prevention of water hammer.
Water hammer, also known as hydraulic shock, is a phenomenon that occurs when a fluid in motion is forced to stop or change direction suddenly. This can cause a pressure surge that may lead to pipe rupture, equipment damage, or even structural failure. To prevent water hammer, several strategies can be employed:
1. Use of Air Chambers: Installing air chambers can help absorb the pressure surges by providing a cushioning effect.
2. Slow Down Valve Closure: Closing valves slowly can prevent the rapid deceleration of water flow that leads to water hammer.
3. Proper Pipe Design: Ensuring that pipes are properly sized and laid out with appropriate slopes can help reduce the risk of water hammer.
4. Pressure Reducing Valves (PRVs): These can be used to maintain a consistent pressure level in the system.
5. Check Valves: Installing check valves can prevent backflow, which is a common cause of water hammer.
6. Surging Devices: These devices can help to control the flow of water and reduce the impact of sudden changes in velocity.
7.
Regular Maintenance: Keeping the system well-maintained can prevent blockages and other issues that can contribute to water hammer.
8.
Hydraulic Analysis: Conducting a thorough hydraulic analysis can help identify potential areas where water hammer might occur and allow for proactive measures to be taken.

Shut off ?the main water valve.Open the building's highest water faucet.Drain all water from all pipelines by opening the lowest water faucet, normally located in the front yard or the basement of the building. ... Once water has stopped flowing from the lowest water faucet, turn it off, and open the main valve.
