When sizing compression tanks, what is an important aspect to consider?

When sizing compression tanks, considering the volume of water in the system is critical because the tank must be able to accommodate the expected water volume and pressure fluctuations. The volume dictates how much air cushion is needed in the tank to effectively manage the pressure in the plumbing system, especially during water draw-off and refilling.

This ensures that the system operates efficiently, maintaining consistent water pressure and preventing issues such as water hammer or inadequate flow. Understanding the volume also helps in selecting a tank that can handle thermal expansion, thereby protecting the plumbing system from damage.

The other factors, while they may influence certain aspects of tank performance or installation, do not directly relate to the specific sizing requirements of the tank in relation to the system's water volume.
