Product Description

Max Water RO Water Tank

TANK

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. Plus, our closed expansion tanks are designed to keep your water pristine and safe from outside elements.

Your health is paramount. 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.

No one likes unpleasant odors in their water. 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.

Bought this to replace the tank on my Pentair kitchen unit. It was a drop-in replacement that works so much better! The only issue was that the tank line diameter was too small. So I used the valve from the old unit. So, that’s something I should’ve checked out better, but no harm done.As for delivery, if you’re in a rush, look elsewhere. When purchased, it looked like fast delivery, but it came from Canada and took a long and winding route to CA.Good purchase overall. More than four stars, not five.

Great Replacement tank for my GE RO Plant! Just for others reference, I broke my coupling to my tank and this replacement worked. I had Model: WS32X10019 - if you have this original GE tank, this one will work as mine did.

Maybe a bit more than I wanted to spend, but installed easily, was the correct size for my needs and has performed well in the first week it has been installed.

It replaces the last one I had since 2013. It had failed. I installed it myself, just make sure to use thread seal tape.🙄

Worked perfectly, drop in replacement for my last replacement. Hopefully this one will last a while, the quality has been slowly declining over the last few I've bought. Too early to say anything about this one.

We needed to replace our old osmosis bladder. This was priced right and works great.

Container was dented on the top and hair from the previous owner was on top of the tank Contacted seller, they said dent doesn't impact the performance. They said nothing about the hair on the top of the tank. They told me I bought it from a sidebar, I simply clicked "Buy It Now". They also stated I should have known by the price, I put in the model number and searched. Guess next time I will go to Lowes or Home Depot instead of using this vendor. Be wary!
