Residential Pre-Pressurized Reverse Osmosis Water Storage Tank

Our Journey Began with a Simple Belief: Clean Water is a Fundamental Necessity

Since 2007, Max Water has been on a mission to bring reliable filtration to every home, driven by the belief that clean water is a basic requirement. Our passion is to make your life easier with hassle-free water filtration, and it brings us joy to see you smile.

The Ultimate RO Water Storage Solution

Waiting for water to trickle through a reverse osmosis membrane can be frustrating. That's why most home RO systems feature a storage tank, ensuring you get purified water instantly whenever you need it. These tanks provide a steady and reliable flow of water, making your experience hassle-free. Moreover, our closed expansion tanks are designed to keep your water pristine and safe from external factors.

Your health is of paramount importance. Lead in drinking water is a serious concern, which is why we've replaced brass and copper with stainless steel connections in our PAE expansion tanks, ensuring your water remains lead-free and safe for your family.

Unpleasant odors in water can be undesirable. Our post-cured diaphragms prevent any bad smells from developing, keeping your water fresh and clean. Additionally, our tanks are NSF certified (standard 58) and CE approved (PED), giving you peace of mind that they meet the highest international standards for safety and quality, and can be used with confidence anywhere in the world.

Our RO storage tanks ensure a steady and reliable water flow, reducing the wait time for purified water and providing immediate access when needed. Featuring stainless steel connections to prevent lead contamination, these tanks meet high safety and quality standards with NSF and CE certifications.

Maintains Water's Purity, Durable Material

Post-cured diaphragms prevent bad odors, and the butyl diaphragm with a polypropylene liner maintains the water's purity and freshness. The metal diaphragm design offers superior pressure resistance and stable water outflow, ensuring the tank's long-term durability and dependable performance.
