Replacement Tank
Hud•August 22, 2017
My reverse osmosis filters stopped making the full amount of water. So I purchased this item to replace my last unit. It arrived on time and seems to work well at this time.
Easy replacement

I had an older tank left to me by the previous owners. Was told the tank was bad because we would get a quick burst of water and then I trickle after that. I replaced it with this in the same amount of time it took me to remove all the crap from underneath the sink. Took a good 2-3 hours to fill completely, ran the tank out until a trickel and then let it refill again. Works great! I can fill a gallon in just over a minute.
excellent product and customer service

I had purchased this in Jan 2016 and some time in the beginning of this year (exactly one year later), my tank stopped working. I emailed express water through Amazon about the problem and inquired if I can file a warranty claim. Express water asked for my order number and after I provided it to them, they immediately sent me a replacement water tank within a couple of days...
I am extremely satisfied with the excellent customer support and customer orientation shown by Express water.
Will definitely recommend Express water to everybody.

Worked perfect . My filtration system wasn't putting out enough water and it had low pressure as well . After trouble shooting I figured that I had a bad tank so I replaced it with this one and its working perfectly !!! Very good product.
Good Tank. . .

My air blatter blew in my original tank. RO system was installed when I bought the place. Always took a day to fill the tank. Now with this tank, the system is filling great and I am actually getting 36 GPD out of the system. A new membrane and restrictor helped a bunch too.
