PressureWave™

PressureWave™ series tanks are built for durability and long-lasting performance, making them a top choice for both residential and commercial water systems. These tanks feature a high-grade butyl diaphragm securely held against the tank wall by a steel clench ring, ensuring that they remain leak-free and maintenance-free. The patented stainless steel water connection provides a dual seal for added security, while the virgin polypropylene liner ensures that your water remains uncontaminated. Available in horizontal, vertical, and inline models, PressureWave™ tanks are versatile enough to meet a wide range of applications.

Disclaimer: The recommendations generated by this Tank Sizing Calculator are based on user-provided parameters and are intended for preliminary guidance only. Ultimate responsibility for the selection of appropriate tank size resides with the user. It is imperative to consult with your GWS representative or a certified professional for validation and advice in critical or complex applications, ensuring compliance with relevant standards and operational requirements.

Select the ideal pressure tank for any application - residential, commercial, or industrial. Our calculator provides tank size recommendations based on system needs to ensure optimal performance. Simply input your system type, pump start/stop pressure, flow rate, and minimum pump runtime, and the calculator will recommend the correct tank size for optimal system efficiency.
