– RO Water Filtration System Expansion Tank – 11 Gallon Water Tank – Large Reverse Osmosis Water Storage Pressure Tank

Bought this as a second storage tank for my reverse osmosis system as I added an ice maker and needed more available water. Has increased the water pressure to everything connected to it. Rhe durability is great and functions flawlessly. It fits it under the ice maker table in the garage. The price was right for the size.

Original RO system came with a paltry 3 gallon tank, of which only 1.8 gallons was for water storage. I didn't know how awful that was until the membrane in that tank died.Determined to ensure we always have enough RO and plenty of pressure in the line, I doubled the desired capacity, and then DOUBLED it AGAIN. So, the 8 desired gallons of liquid required a 10-12 gallon tank.The tank came with ZERO installation hardware. I stole the old valve from the old tank which worked out just fine. By morning, we had 8 gallons of RO water flowing. I strongly recommend this tank!

I used this to adapt the tank to my current expresswater RO system. EZRODI 2 Pack RO Water Tank Valve Connector for Reverse Osmosis Storage Tank (2, 3/4 in. Female Thread and 1/4 in. O.D. output) https://a.co/d/j7VZGUK. Then I used a Y John guest fitting to connect both tanks in series. Don't listen to the instructions. Says takes 3 to 5 hours to fill tank. NOT TRUE, took the entire day, you're splitting pressure among to tanks and increasing real capacity to 11gallons+. Be patient and let the system do it's thing. Check your tank pressure on the tank, if it's below 10 psi fill it to 10 psi. If the pressure is too low the system will continue to discharge and not close the the valve after tanks fill up. No one, I mean no one in any of the reviews or forums could figure this out. I had to trial and error to find this solution. I see many people complain about continual water discharge after 3 to 5 hours of letting your system tank fill. If your system is new or you have new filters it is the tank pressure. To test the stop valve you can close the tanks from the the system, if the water stops discharging means your valve is working. Tank is super high quality and tank bladder was at correct pressure (10psi). EXPRESSWATER is a fantastic company.

Very misleading.Their instructions I looked at showed the tank, a 90 elbow and adapter.When I received the tank, that is all it was, just the tank. No connectors, no adapters.Don't know what some of the other reviewers are talking about when they say they installed the included connector.For the price of this tank, they could have included the valve.They do on the smaller tanks.And I can't use the valve from my smaller tank, this opening is much bigger, 3/4", so now I have to wait another day for a new valve.2 stars for my inconvenience and for their deceptive advertising.They should be clear in the item description that additional parts WILL be needed to put into service.

I had a lot of trouble getting a good reliable no leak connection to the tank. I used "Give me the green stuff" and Teflon tape and it was still start to drip after a couple of days. The threaded pipe coming out of the tank does not seem to be tapered and therefore resistant to making a good tight seal.

Easy to install as long as you have enough room. I have a corner sink with extra room on each side so was able to get tank tucked away in a corner with no problems. My only problem the the free 3/8 valve is to short and when it is tightened up to the free reducing bushing provided you cannot turn on the water fully at any position. The company should try the fittings before furnishing them with the tank even if at no charge.

Makes water taste really bad like dirt. Company will not accept returns.

The product did not come with any of the adapters. Just the container in the box. In all fairness that is what they describe on here, despite some customers saying they received connectors. The company was helpful on their 1800 line and the operator helped me find the right connectors for my system. I was told that only tanks smaller than 11 gallons come with connectors for reverse osmosis systems...some of the reviews on this product may be for the smaller tanks? Overall works great. Diaphragm came pressurized to 8psi which is standard and easy to check and maintain. You can not rely on local hardware store (HD or Lowes) to find the right connectors. I spent an hour there and came home with useless adaptors. Call the company and they will expertly help you.
