Quick Answer
Yes, tank height should be considered in your installation plans to ensure proper water pressure and system performance.
Importance of Tank Height
A water pressure tank’s height can significantly impact the system’s overall performance. When a tank is too high, it can create excessive water hammer, leading to damage to pipes, pumps, and other system components. Conversely, a tank that is too low may not provide sufficient pressure to reach all points of use, such as irrigation systems or upper-story faucets. A good rule of thumb is to maintain a tank height of no more than 8-10 feet above the pump to avoid excessive water hammer.
Determining Optimal Tank Height
To determine the optimal tank height for your installation, consider the following factors: the system’s total head, the pump’s suction and discharge pressures, and the tank’s capacity. A general guideline is to maintain a 1:6 ratio between the tank’s height and the surrounding elevation. For example, if the surrounding elevation is 100 feet, the tank’s height should be no more than 16-20 feet. Additionally, ensure that the tank is properly vented to prevent airlocks and ensure a smooth flow of water.
