Systems Tank-4 4 Gallon Residential Pre-Pressurized Reverse Osmosis Water Storage Tank

Works great, easy to install, I replaced a 10 year old tank that started leaking at the Schrader valve, this tank did the trick. Amazing volume of water before it starts to slow.

Works great! I got the water pressure back. Easy to install.

Working well, capacity seems to be as advertised. No funny orders or taste. Easy to install. Preset pressure was perfect. Replaced the old 4 gallon that couldn’t keep up with family needs.

Great replacement. Great buy.

It would have been five stars if it wasn't for the unwillingness of the company to meet the customers half way. Not everyone is a trained plumber and some instructions would be very helpful. Not having the connector valve included felt almost like a prank. I had some trouble finding the right one. When it comes to rubbery smell and taste that comes from the rubber pressure "gut" inside of the tank, there is a simple solution no one knows about: an additional activated carbon filter cartridge placed inline between the container and the faucet. Took me almost a year to figure it out. It didn't have to be this way. Those are simple pieces of information that help solve major issues in 5 minutes! Otherwise, once it was all solved, it works fine and makes my life easier. Now I'm a certified plumber. (No, I'm not but I sure learned a lot about the subject).

Perfect replacement to our old system, all we know is it was about 13 years old and we have had poor pressure for two years, right after last filter change by local company. Finally wanted to replace all the filters, tank and membrane all at once. It was very easy to do. Great pressure out of the new tank that lasts for almost 2 minutes on full pressure, then pressure lowers consistently for a couple more. It hits the front of our sink now. So we will not even need to turn the gooseneck on all the way on like we have been. Would recommend and will be back for more filters, etc in the future. This was the first time doing it myself and we replaced the tank AND membrane along with the filters for cheaper than JUST filters cost through the local company,

I bought my APEC system in 2018. I've done yearly filter changes, and the occasional RO filter replacement. The system ran great. Then several weeks ago, I noticed the water was coming out in much lower quantities. I could maybe get half a liter out and then it would just dribble. It was like it had an inflamed prostate. I read some other reviews and decided to buy this tank. Problem fixed! I get a nice, full flow of water and much more than a little tinkle. The tanks are only supposed to be good for five years, and then the diaphragm inside them slowly loses pressure which means the tank will fill, but you won't get very much water out of it since the diaphragm has lost pressure. After I removed the old tank it was almost full and there was over 2 gallons of water still in it that wouldn't come out of the faucet anymore.

I bought this to replace the stock tank for my RO system from GE. The old tank was barely putting out two cups of water at a time. However, the stock replacement was going to be around $150, so I was looking for a cheaper option. Since this tank is carried by the same store that I bought the RO system from, and they have it labeled as an "industry standard" in terms of pressure settings, I decided to give it a try. And so far, it works great! Much better pressure, and I get a lot more water out of the system at a time. Notably too, the water tastes better! Maybe because it's not mixing with old, stagnant water that can't be expelled. Super easy to install! Bought a shut off valve fitting to connect the tank to the plastic line of my system, and managed to connect it easily. Be sure to use plumbers tape on the fitting. I also used an O-ring for good measure. So far, no issues with leaking, as other people are reporting in their reviews.
