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

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.

This 14 gallon tank is perfect for our 4 person household with several aquariums. RO Water is always at the ready. We had to purchase an additional valve that goes in the bottom but not a big deal. We are happy with the build quality and it has been working without problems for a couple of months now. Unlike the pressure tanks I have used in the past this has the port in the bottom vs. the top.

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,

We've had an RO system for six years but recently, the volume of water available was dwindling. I did some searching on the internet and learned that the problem might be that the diaphragm in the tank might have developed a leak. I also learned that these tanks frequently fail after five to eight years. In addition to ordering this tank, I also ordered a new tank-top valve ( https://www.amazon.com/dp/B08RSMHWJ6?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1&th=1 ). That allowed me to turn the valve off on the old tank and remove it without risking spraying water all over the kitchen. Installation was easy and fast and within a few hours we were back to having plenty of drinking water.

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.

Great replacement for old tank I had for over 10 years. Good quality and comes pre-charged. No instructiona necessary, just remove old tank, apply plumbers tape and screw on fitting and attach water line, then check for leaks. Fits most undersink RO systems. One tip: you will need to wait several hours for the tank to fill. At first it will seem like the tank is not filling up, but just give it several hours and it will be full.

My 10- year old RO tank finally quit pressurizing my filtered water. This tank arrived quickly, and at a good price. Installed easily. I cut my old tank in half to see the failed rubber bladder inside. (Used my metal-cutting Makita circular saw. What a great tool, but I digress.) See attached photos to see the innards.

Works great

Installed it in an RO system feeding a fridge ice maker and water dispenser. Water source is a well and the RO system includes a pump as well, to guarantee water pressure requires by the fridge. The tank is well built and seems to work as desired. The only inconvenience is having the valve at the bottom of the tank, making it difficult to access.

Works OK 2 weeks in

Me gustó que fuera blanco, otras marcas tienen colores más feos en estos mismos tamaños como crema o azul y como en mi caso el tanque está expuesto, así que es importante que se vea bien. Solo hubo 2 cosas que no me gustaron: 1. El material y el diseño de la base es pobre: para empezar, la parte de la base que está en contacto con el piso no es ancha, así que el peso se recarga sobre un borde más o menos delgado, con el paso del tiempo y el peso continuo, puede que se termine por vencer el plástico y rompa el conector de agua; la base no está fijada al tanque, lo que tiene sus ventajas en comodidad (a la hora de conectarlo resulta mucho más sencillo que con los tanques de base fija) pero pienso que también le resta estabilidad. Respecto al diseño del tanque y de la base, considero que es un problema porque el conector de agua mira hacia abajo y requiere de una pieza en 90°, por lo que cualquier otra pieza que no sea la original será complicada de utilizar porque la base da poco espacio de maniobra respecto del suelo y eso genera mi siguiente problema. 2. No se incluye el conector del tanque, por lo que es imposible usarlo de inmediato si no se ordena la pieza necesaria con anticipación, lo cual me parece totalmente absurdo. De manera que si planeas comprarlo, será mejor que también consideres el precio del conector 3/4 NPT a manguera de 1/4 que no vende Amazon México, sino Amazon EEUU y que en este caso, cobra envío aún con prime, así que no es precisamente barato, aun si está en oferta.

BUENA CAPACIDAD

Came damaged tank looks good but dinged in 2 different spots
