APEC WATERSystems Tank-4 4 Gallon Residential Pre-Pressurized Reverse Osmosis Water Storage Tank

Was having issues with low pressure. Replaced all four filters. Still low pressure. Checked old tank and it had no pressure and when attempting to add air water was coming out of the air valve indicating the old tank was bad. Ordered this and it was pretty simple to install. After I installed it I still had the same issue and the tank was not filling up with water. Thought I was defeated but the next morning it was full and has been working great. Just needed some time I guess. The new tank does come pre pressurized. This came with a stand but not a new valve. I was able to use the old one.

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 was a great replacement and reasonable. The pressure was just right on it and now problem solved. Before the bladder on the inside of the old tank was just worn and I was getting minimal water out. Now I get a good amount of water from the tank and the flow is perfect. I did not order a new valve but just took the valve off the old tank. The only thing that I would emphasize is to make sure to wrap the valve with teflon plumbers tape and then screw it on to the new tank. That will prevent leaking and will fit snug and tight.

Worked perfect for my damaged under sink RO filter. Thanks!

After my tank broke, I upgraded to this larger size so glad I did plenty of water install very easily being pre-pressurized there was no problem. I did run a flush because I had new filters installed, and I always do that anyway but so glad I upgraded to a larger tank Fittings are all on the bottom, but there is enough clearance to do what you have to a lot of tanks the fitting is on the top.

Why did you pick this product vs others?:Large size. Holds 10 gallonsTank is solid be sure to order the valve for connection and have it in the right place when you fill it it is heavy.

Worked perfectly for my APEC RO system. OEM replacement.

it works and is easy to install. it comes with 7 psi already in the tank so all you have to do is remove the old tank and put in the new one.
