About This

  • Heavy Duty & Durable Construction: Max Water NSF Certified tanks are built for long-lasting use. With a max working pressure of 100 PSI and a smooth internal air vent cap to prevent diaphragm damage, the tank provides reliable water storage. Pre-charged at 6 PSI for convenience.
  • Safe, BPA-Free Materials: Made with food-grade, BPA-free plastic components that meet industry standards. Designed to store water safely and reduce potential exposure to plastic contaminants.
  • Quality Tested: Every tank undergoes rigorous quality checks to ensure it meets industry standards for safe and durable water storage.
  • Versatile Applications: Equipped with a 1/4" stainless steel connection compatible with Reverse Osmosis water storage tanks, pump tanks, and thermal tank applications.
  • Optimal Storage & Space-Saving Design: Holds approx. 4.4 gallons at 100 PSI (3.2 gallons at 60 PSI). Tank measures 10.5" diameter × 13.5" height (15.75" with valve & base), making it ideal for most under-sink residential RO installations. Actual water output depends on incoming pressure and RO system efficiency. Typical delivery ~3.2 gallons at 60 PSI.
  • Designed to Outperform Standard Tanks: Compared with typical water storage tanks, Max Water tanks offer stronger materials, improved diaphragm protection, and better pre-charged readiness—providing a more reliable and long-lasting solution.
  • Replacement 1/4" Tank Ball Valves are available separately — search ASIN: B07DRPW4B7 on Amazon.
