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

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.

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.

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.

We purchased this pressure tank to replace our old tank that had failed. Our RO system is located in the basement and this 11 Gallon tank has enough capacity to pump upstairs without a booster pump to the dispenser at the Kitchen sink and Refrigerator/ice maker with no problems and adequate pressure. Most tanks seem to have a 1/4" water outlet and this tank has a 3/4" water outlet, which I think gives more volume and added boost to the upstairs. Tank stand, fittings and a 3/8" turn off valve were all included, so extra trips to the hardware store were not needed to hook up. Very satisfied so far.

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.

It works! It comes with air in the tank. Mine measured 9psi. I expect to have to put air in it. Leave it over night to fill. The water come out great and going from a 2 gallon tank to 11 gallons is even better.

Comes with 0 instructions at all and it is NOT 1/4th connection it is 3/8th connection I had to buy more parts for a second time after ordering this because it was not labeled correctly in the description. It seems like it's good quality materiel and it's the perfect size but the annoying bs I went through after I ordered it to get it to work was why I only gave it 4 stars.
