Is it feasible to combine different tank types in one system?

Choosing Compatible Tank Types

When combining different tank types in a single system, it’s essential to select tanks with compatible materials, such as stainless steel, polypropylene, or fiberglass. This ensures that the tanks can handle the water pressure, temperature, and chemical exposure without compromising their integrity. For instance, a stainless steel pressure tank can be paired with a polypropylene storage tank.

Tank Sizing and Pressure Compatibility

The key to successful tank combination is ensuring that the tanks are properly sized and pressurized. A general rule of thumb is to size the pressure tank according to the system’s peak demand, while the storage tank should be sized based on the system’s average water usage. When combining tanks, it’s crucial to ensure that the pressure tank can handle the maximum pressure of the system, which is typically 30-100 psi, and that the storage tank is designed to withstand the lowest system pressure.

Practical Considerations

In practice, combining different tank types can be achieved through various techniques, such as using a common piping system or installing a pressure-reducing valve to regulate the water pressure between the tanks. For example, a 50-gallon stainless steel pressure tank can be paired with a 1000-gallon polypropylene storage tank, provided the piping system is designed to accommodate the pressure differences between the two tanks.
