Quick Answer
The location of your tank affects water delivery by impacting water pressure, flow rate, and system overall efficiency. A higher tank location generally provides better pressure and flow rate. However, this comes at the cost of increased installation cost and potential structural load.
Tank Location and Water Pressure
The height of a water pressure tank has a direct impact on the available water pressure at the point of use. A general rule of thumb is that for every 2.31 feet of elevation gain, you gain 1 psi (pounds per square inch) of pressure. For example, if your tank is 20 feet above the point of use, you can expect to gain about 8.64 psi (20 feet / 2.31 feet per psi). However, this also means that if your tank is located in a lower position, you may require a booster pump to meet the desired water pressure.
Tank Location and System Efficiency
A higher tank location also affects the overall efficiency of the system. When a tank is elevated, it is often necessary to use a longer pipe run to connect the tank to the point of use, which can lead to increased energy losses due to friction. This can result in reduced flow rates and increased energy consumption. To mitigate this, it’s essential to use larger diameter pipes and to minimize the number of elbows and tees in the pipe run.
Best Practices for Tank Location
When deciding on the location of your water pressure tank, it’s essential to consider the overall system configuration and the specific requirements of your application. A good starting point is to locate the tank as close as possible to the point of use, while also considering factors such as accessibility, structural load, and visual impact. If a higher tank location is required, be sure to carefully calculate the potential benefits and drawbacks to ensure the best possible outcome for your system.
