    N. Krumpe | 4 out of 5 Stars!

    The last time I replaced my RO filters, I knew my tank was bad...the water just sat in the tank. I'm pretty sure its bladder had broken. I almost bought a replacement tank from Watts, because I've been using their replacement filters ( Watts 5-PK-4SV Premier 1-Year 4-Stage Reverse Osmosis Replacement Filter Kit, 5-Pack ) for the past couple years and have been very happy. However, their tank cost with shipping seemed pretty high.

    So, I searched Amazon, and was impressed at the high reviews this iSpring tank is getting.

    1) I didn't need to buy any additional connectors. I just removed the old valves from the old tank and put them on this one. If you have some teflon tape, you might not need anything else. (Of course, this depends on your current setup...if your old tank has a 1/4" threaded connector, then this should be a good match. If not, you can by a cheap adapter and still make this work.)

    2) It's ready to go, right out of the box: Already pressurized, all I needed to do was swap out the old tank and I was good to go.

    1 Complaint:
    The packaging was simply awful. Imagine forcing a cylinder into a box that's too small. It will push out the sides of the box, and the box will take on a cylindrical shape. That was the case with this tank. There was no padding to protect the tank. As a result, it was dented in three places. I considered sending it back, but other reviewers have noted that the tank can still work fine with the dents. So far so good, but someone REALLY needs to improve this. I'd be willing to spend an extra dollar or two on the tank if it meant safer shipping. The only reason I did not give a 5-star rating was because of the damage to the tank.

    1 Note:
    At first, I thought I received the wrong tank. This says it's a 4-Gallon tank. However, read the details and you will see that it actually is only designed to hold 3.2 gallons of water (I assume this is because of the space taken up by the tank's bladder.) Not a big deal for me, but just make sure you know what you're getting.

    All in all, other than the bad packaging, this tank is a great replacement at a great price.
