why is water tube produces the noise while pumping ground tank to upper tank at 6th flour ?

The noise you hear when pumping water from a ground tank to an upper tank on the 6th floor could be due to several factors. One of the main reasons is the water hammer effect, which occurs when the flow of water is suddenly stopped or changed direction.
When a pump starts, it pushes water through the pipes and creates a pressure wave. As the water flows upward, the velocity of the water decreases due to the smaller pipe size on the upper floors, causing the pressure to rise. When the flow is suddenly stopped, such as when a valve or tap is closed, the pressure wave traveling through the pipes can cause vibrations and produce noise.
To minimize the noise in this situation, you can consider these steps:
1. Install shock absorbers or surge tanks: These devices can help absorb pressure waves and reduce the water hammer effect.
2. Use flexible piping: Using flexible pipes or adding expansion joints can help absorb the pressure waves and minimize the noise.
3. Adjust flow rate: Modifying the flow rate of water through the pipes can help reduce the water hammer effect. Slowing down the pump or adjusting valves can help regulate the flow and reduce noise.
4. Insulate pipes: Applying insulation to the pipes can help absorb or dampen the noise generated during the water hammer effect.
It's important to consult with a professional plumber or engineer who can assess your specific situation and recommend the most appropriate solution to eliminate or reduce the noise.
