Product Description

Water goes through a reverse osmosis membrane very slowly and people don't have the patience to wait a long time to get a cup of water. For this reason the residential RO units need a water storage tank to store the purified water. The RO tanks can deliver stable and constant water flow when the faucet is opened. The concern that pollutants might come from air or animals with the use of an open tank favors the use of a closed expansion tank. Lead leaching into drinking water causes health risk, brass and copper are banned from bing used in purified/drinking water. This tank uses stainless steel connections to avoid the lead leaching concerns. This tank is tested by independent third-party to meet NSF/ANSI Standard, and CE approved under the PED (pressure equipment directive).Features:Stainless steel connection built for Reverse Osmosis water storage tank; pump tank & thermal tank applications. Brass cap with internal O-ring guarantees no air loss from air-vent. Smooth internal air vent cap prevents diaphragm damages. High-grade butyl diaphragm, post-cure procedure insures a tasteless and odorless water chamber Tested by independent third-party to meet NSF/ANSI Standard. Specifications & Dimensions:Height: 28\", Diameter: 15\" Tank size: 20 gallons (14 G water + 6 G air) Shipping weight: 31 LBS Packing dimension: 16w x 16d x 30h

iSpring Pressurized Water Tanks

At iSpring, we look beyond technology to make high quality drinking water accessible for all households. We provide our customers with professional water solutions to any water concerns they may have.

  • T32M (3.2 gal)
  • T55M (5.5 gal)
  • T11M (11 gal)
  • T20M (20 gal)
  • T40M (40 gal)

How does it work?

iSpring pre-pressurized tanks are great for use in whole house water storage with your reverse osmosis system or other water filtration system. The water filtration process is on the slower side, so a pressurized storage tank is typically required to supply water from the system on demand. Your water filtration system will fill the tank to capacity, and when you open your water dispenser, the water is sent out by the tank's pressurized air bladder.

  • All tanks have a maximum working pressure of 100 psi.
  • iSpring Pre-pressurized tanks are tested by independent third party against NSF/ANSI standard (61 for Drinking Water System Components) for material safety and structural integrity requirements, 2018

iSpring tanks have a special surface treatment on the metal body that prevents rust and dent.

All of our metal tanks pass pressure tests before we ship them out to customers.

Unlike traditional plastic, stainless steel that does not break or strip easily is used in our tank valve thread and pressure check valve.

Inside all iSpring tanks, a durable butyl diaphragm with post-cure procedures provides a tasteless and odorless water chamber.

    Great tank, terrible hardware
    Going from a 4 gallon tank to this 11 gallon tank is an obvious upgrade on its own. The tank comes with a nice stand and some hardware. I am happy with everything except the hardware.No matter what I tried, there was a leak. First, there was a leak coming out of the area you thread the valve into what I’ll call the main nut that goes over the top of the tank. I read previous reviews and saw that many others mentioned issues with the hardware and leaks. So, I tried a lot of teflon tape. Still leaked. I did some research and came across Blue Monster Pipe Thread Sealant. Turns out I had some which was great. Applied it and solved that issue. Then a new leak formed where the tubing is inserted. Again, applied the BM Sealant and problem solved. Then a leak appeared from the nut that secures the red shut off valve. It was then that I realized I needed to invest in some new hardware.I stopped at a local plumbing store and got some great suggestions as well as a shopping list. The items they recommended are shown in my second picture:1.) Blue Monster PTFE Thread Tape2.) 1/4” Brass Hose Barb3.) 3/8” ClampThese three items solved my issue 100%. No leaks whatsoever.I was skeptical because doing this would eliminate a shut off, so I just added a shut off between the lines.Hope this helps anyone having issues with their hardware.

    5.0 out of 5 stars Excellent Upgrade for RO Systems
    Reviewed in the United States on January 10, 2024
    I recently had to replace my old 4-gallon RO water tank that was leaking, and I couldn't be happier with my choice to upgrade to the iSpring 5.5 Gallon Residential Pre-Pressurized Water Storage Tank.

    The first thing that caught my attention was the quality construction of this tank. It looks and feels robust, giving me confidence in its durability. The 5.5-gallon capacity is a significant improvement over my previous 4-gallon tank, providing more water storage for my household needs.

    Installation was a breeze, thanks to the included top valve. The easy-to-follow instructions made the process straightforward, and I had it up and running in no time. The top valve not only adds to the convenience but also ensures efficient functionality.

    I appreciate the additional water capacity, especially during peak usage times. With this tank, I no longer have to worry about running out of purified water. The iSpring T55M has exceeded my expectations with its quality and ease of installation.

    If you're in need of a reliable and high-capacity water storage tank for your RO system, I highly recommend this tank It's a top-notch product that delivers on quality and increased water capacity. Five stars all the way!

    5.0 out of 5 stars The ispring RO 500 AK filter System continues to exceed my expectations.
    Reviewed in the United States on November 23, 2023
    I have used an iSpring tank RO system for about six years. I was pleased with it, however moving into a tankless system I wanted to make sure I was getting the best on the market. I read many reviews on several different RO systems. They all sounded pretty good, but what jumped out for me with the iSpring system reviews was the exceptional customer support people raved about.

    Also, since I was going to connect mine up to my refrigerator ice maker and water dispenser I was very alert to any comments about that type of installation. Interestingly, about 3/4 of the reviews suggested that I would be fine with the iSpring tankless system with the remaining suggesting that it didn’t work well.

    I called hiring iSpring customer service. As reviewed, the response was very fast. They suggested that I would be happier with their T32M tank connected the tankless system. I ordered both I installed the tankless system and everything worked pretty good. The refrigerator water dispenser worked with a little pulsating action on the water stream. I then connected the tank. It now works superbly. The tank keeps constant pressure so the water flows instantaneously. I also installed the RO water faucet. Since you have to activate the filters by running the system for 30 minutes, it would’ve been a real pain to stand in front of the refrigerator water dispenser doing that.

    I enthusiastically recommend the system.
