Description

iSpring T32M 3. 2 Gallon Pressurized Storage Tank for Reverse Osmosis (RO) Systems The reverse osmosis process is on the slower side, so a pressurized storage tank is typically required to supply water from the system on demand. Your RO system will fill the T32M tank to capacity, and when you open your RO water dispenser the water is sent out by the tank's pressurized air bladder. The concern that pollutants may be allowed in when using an open air tank favors the use of a closed expansion tank such as the T32M. The tank uses stainless steel connections to avoid any leaching concerns, tested by independent third-party to meet NSF/ANSI Standard. From the Manufacturer NSF Certified 4.0 Gallon Water Storage Tank (3.2 gallon draw- down) 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 delivery stable and constant water flow when the faucet is opened. The concern that pollutants might come from air or animals with the use an opened tank favors the use of a closed expansion tank. Lead leaching to drinking water the cause of health risks, brass and copper are banned for use in purified/drinking water. This tank uses stainless steel connections to avoid the lead leaching concerns. This tank is NSF approved under standard 58, 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. - Smooth internal air vent cap prevents diaphragm damaged. - High-grade butyl diaphragm, post- cure procedure insures a tasteless and odorless water chamber - NSF 61 and 58 listed. - IAMPO approved. - CE Mark approved TANK BALL VALVE NOT INCLUDED Specifications & Dimensions - Height: 14", Diameter: 11" - Actual tank size: 4.0 gallons - Tank storage capacity: 3.2 gallons - Shipping weight: 9 LBS

    • What a surprise! Great tasting water!
Size: UF System – Nickel Faucet
This is an excellent water filtration system! It provides great tasting water as well. The installation was very easy and the system overall is the perfect size, with not being too small or large. Fits great under your kitchen sink! On the taste, after running it for the first time for 15 minutes I was not impressed, at all! I was actually ready to box it all up and send back, but decided to give it more time. I ended up running it for about 30 minutes or so and that made the whole difference!!! VERY good, tasting water! The price is excellent too! ... show more

    • Great Complete System at a great price
Size: UF System – Nickel Faucet

Got tired of the water dispenser in the frig, which would drip onto the floor from constant use (family of 4). Got a new frig without one and added this filter to a new sink and faucet which is so much more practical and convenient, especially making coffee each morning. I bought this based on the reviews and 0.01μm as opposed to 0.5 μm by other leading brands. I also wanted a Tankless system that required no power but provided great filtering. 4-Stage High Capacity that removes 99.99% Contaminants is impressive - but time will tell (installed a week ago). The Brushed Nickel Faucet is very nice and dispenses at a fast rate, it also matches my new faucet :). No leaks but I did place a mud tray under it and will add an H2O sensor - a good idea from another review - as I was not liking the sensor that came with the kit that added complexity to the hose hookup. Installation was easy - watch their video. Emailed customer service for the warranty and they were great (thanks Francis!). So far I'm very pleased. Water tastes clean / no chlorine or otherwise. Replacing the cartridges should be easy - don't forget about that when you install this filter - keep it simple and accessible. ... show more

    • Larger than expected
Size: 5.5 Gallons
Read the dimensions before ordering, I thought it would be smaller. Works great, dispenses water quickly, you can adjust the pressure easily. The metal body is definitely built well, hope the insides are of equal quality. Did not notice any taste what so ever. Super easy to install, just connect the hose and put it under the sink. ... show more

    • Great Tank, Great Customer Service
Size: 20 Gallons
This is a large 20 gallon tank that holds roughly 14 gallons of clean water for a reverse osmosis system. As a disclaimer, this arrived dented for me, but Sean from iSpring's customer service was wonderful to work with, and he quickly sent a replacement tank that arrived in perfect condition. This has multiple connectors provided, and the connections are done at the BASE of this unit. This works best with 3/8" line. The top part of the tank is where the bladder is, and the water sits near the bottom. This arrives charged and almost ready to use. They recommend flushing this once filled to ensure it is clean. I HIGHLY you do that with tap water prior to using. This takes forever to fill with RO water, so tap is much faster. Enough connectors were provided that I was able to hook this up to a utility sink to fill and drain this several times before install. This works just as well as smaller tanks, but the pressure is maintained much longer with this size tank. Overall, I am very happy with the performance and value of this tank. ... show more

    • Almost perfect; beware of hose fitting on the valve. I had to substitute.
Size: 4 Gallons
Product: iSpring T32M Pressurized Water Storage Tank with Ball Valve for Reverse Osmosis RO Systems, 4 Gallon, 1/4" Tank Valve Included Purchased: 1-10-2024 Received: 1-12-2024 Reviewed: 2-5-2024 I replaced a faulty 2.8 gallon tank with this larger 4 gallon "iSpring T32M Pressurized Water Storage Tank with Ball Valve...". We drink RO water for health reasons. Since we were without RO water due to the faulty existing tank, I promptly installed this new tank. Unfortunately, I did not realize that the tank came with a 1/4 inch fitting, which is too small for my existing water line! Since I was installing a larger tank, I didn't consider the new fitting being smaller than the fitting on my smaller tank. The only reason I did not give this product (5) stars is because I had to swap out the included valve with the valve from the old tank. This is because the existing plastic RO water line is larger than the supplied 1/4 inch valve fitting. This is my mistake for not noting it when I purchased it, but then too, since this is a replacement product, the supplier could have easily provided the optional size valve with the tank, making me and all future buyers VERY HAPPY! Fortunately I had the old valve and it fit the new tank without any problem! If I didn't have the replacement valve then I would have been out of luck installing the new tank. Since I was able to quickly replace the valve, I was able to install the tank and everything is running GREAT! We are really enjoying the larger capacity, and we never run out of on-demand RO drinking water! Now we can fill all of our backup water jugs without running out of pressure and water. Perhaps the company can include multiple fittings of popular sizes so this doesn't happen to the next buyer! All the tubes in our RO system came with the RO system and were installed correctly. The mismatch fitting was not anticipated since we assumed our RO system and the new tank to both be standard. ... show more
