This is the second tank I’ve gotten from Express Water. The first one was for my old house and I loved it. This one is for my new house and I wanted to get one a little bigger than last time. We have plenty of water now, even in the super hot Arizona summers.

I bought a water filtration system online and it came with everything (the system, filters, faucet, storage tank etc…) Everything was of acceptable quality, but the tank was a bit small for me. I needed a bit more storage capacity based on my water usage

This was the biggest tank that would fit under the sink, does what it’s supposed to.

We started to have tons of problems with water flow. We thought it was the reverse osmosis system, but eventually determined that it was the tank. We replaced the faulty tank with this one and now it works even better than when it was new.

I needed more water storage, so I decided to upgrade to a larger-sized tank

The capacity increase made me fall in love again with my RO system. Thanks. Kristy

Needed to replace my old tank. It was a good tank, but it started showing its age. Eventually it got a ruptured bladder. Hopefully this one lasts just as long

Easy install, works great!

My old tank malfunctioned. It would let water in, but something was preventing it from going back out. Rather than paying to repair an already compromised tank, I decided to just buy a different one. I’ve only owned this new tank for a couple weeks but everything seems to be higher quality. Let’s see how it hold up though.

The size of the tank was just perfect to fit under my sink it came pressurized already so it was quick to install

Fit exactly with my existing RO set-up. Just had to hook it up exactly how my previous tank was.

This works great for my ro system

This is a larger than usual tank – taller and larger diameter than the typical under-sink tank (so make sure it will fit). The quality is good – it come pre-charged to pressure and well packed with uninstalled John Guest shut-off valve. The extra capacity is handy if you use a lot of RO water – maintains pressure very well. The painted blue finish is nice – it looks matt in the pictures but is is actually glossy.

Works great. I like the larger size. Replaced a 4 gallon tank.

I’ve had this product (from a previous order) for over a year and never ran into any problems with it. It’s been perfectly reliable the whole time. I’m installing a 2nd under-sink RO system in the house, so that means I need another storage tank. I opted to go with orodering this one again because I know it’s dependable.

This was a replacement for a 3 gallon tank. The footprint is slightly bigger than that tank but is 10x more efficient. The water flow is great and gives you 5.5 gallons of filtered water at a given time. I am very happy with this purchase. I would buy this tank again when it’s time for replacement.

This RO tank is a great upgrade. 6 gallons of water seems to never Run out. Easy installation and good quality construction.

I shopped around a lot and this was the best quality for the lowest price I could find online. So, sometimes if you water pressure from your filter drops, it’s not because your filters need to be replaced or anything is wrong with your system. We did some research and someone suggested we might need a new tank. For us it was because our tank was old and needed to be replaced. We looked into if the tank could just be repaired and we found out it coud not, at least not easily. After we got the new tank our water pressure was perfect. The preset pressure was just right for us. Also, your incoming water pressure can affect how much water your tank actually holds. Different pressures will stretch the water holding bladder different amounts. A new tank turned out to be one of the easiest upgrades we’ve ever done for our RO system.
