Review Image by JTGB JTGB
I bought this tank to replace the one that came with my RO system six years ago that gave up the ghost (my system happens to be installed in my basement) and I took the opportunity to up-size from the original 3.2 gallon capacity normally sized for the typical under-the-sink install. Besides the added water storage, the tank provides for greater overall volume support and I was happy for the included stand to raise the tank off the concrete. The ball valve is a separate purchase so be sure to pick the correct sizing for your system. The ball valve that comes with the small tanks will not fit. My only nit is the tank is packaged to fit inside reinforced cardboard and the shipper was less than kind; thus I was welcomed to a dent in the side of the tank upon unboxing - not enough to return it - there's a bladder inside that holds the water - but a bit of foam protection would be better for residential delivery. More humorously the Apec label on the tank is upside down; thankfully my powers of observation and just enough common sense were strong enough to overcome the discrepancy and thus installed the tank with the valve pointing skyward. For anyone concerned with this DIY project - very little tooling was needed; especially if you have a crescent wrench and quick-connect valves. Was as easy as turning off the water supply to the RO system, relieve the water pressure by running the RO faucet, disconnect the old tank line; screw the correctly-sized ball valve on the Apec tank, reconnect the line; and resume the water supply... then wait a bit for the system to fill the new tank. I checked the air pressure before installing - was set at 8psi out of the box. After filling the tank - I'm getting really good flow at the dispensing RO faucet even when filling up a gallon-size water container. ... show more

    • This is a good quality tank.
Style: Storage Tank
The stand that came with it allowed me to put it on the floor next to my laundry-room sink. I like the fact that it has 3/4" ntp fitting. That made it easy to put a "T" connector. With a reducer, one end of the "T" goes to my RO filter. The other end goes to the faucet and distribution system in the crawlspace. I can fill the tank at the rate that the RO filter can produce. But, With a full tank, I have the flow of a 3/4" faucet! ... show more

    • A fine addition to your RO system.
Style: Storage Tank
Installation was simple. I will say that, going into projects like this, I always assume I'm going to have to pick up a fitting or 2 to make it work. It's simply not feasible for a manufacturer to include EVERY potential fitting for EVERY potential setup. When I added this 14 gallon tank, at the same time I converted my RO-90 to the RO-HI with the 3/8" upgrade kit. So for my installation, I had to get a 3/4" NPT (garden hose fitting, essentially) to 1/2" adapter (brass), a 1/2" to 1/4" NPT nylon adapter, and a 1/4 to 1/4 male to male to fit the 3/8" tank ball valve that came with my 3/8" upgrade kit. My old 4 gallon stock tank is fed from a T fitting running off the 3/8" line between the 14 gallon tank and the final carbon filter, using the original 1/4" line and using a 3/8 to 1/4" pex reducer. This way I didn't lose the 4 gallon tank storage which is now added to the 14 for 18 total (12-13 realistically). System performance is fantastic, and now I never run my tank dry filling up my spaghetti noodle boiling pot! Worth every penny. ... show more

    • Great quality so far

Check the tank pressure with a car gauge mime was a bit over the recommended pressure

    • Good system, but pay attention to the fitting sizes.
Style: Storage Tank
I purchased the kit along with The APEC TANK-14 14 Gallon tank, the APEC Water Systems 3/8" Output Quicker Dispense Upgrade Kit, and (eventually) the APEC Water Systems Tank Ball Valve (3/4" NPTF, 1/4" Output). My purpose was to upgrade my existing system, the APEC Water Systems RO-90 Ultimate Series which I purchased in 2020. Overall I recommend the system, but I did have a couple issues, one my fault, and one Amazon's. So first the issue that was my fault. I originally purchased just the tank and the upgrade kit. I didn't look close enough at the specs and didn't realize that the 14 Gallon tank has a 3/4" male NPT fitting where the smaller tanks have a 1/4" male fitting. The upgrade kit comes with a new valve with a 3/8" tube outlet (as opposed to the 1/4" tube outlet on the standard filter set) but a 1/4" female fitting to mount to the tank. As a result, you can't use the valve with the 14 gallon tank. I couldn't find a version of the kit that comes with 1/4" fitting to 3/4" fitting adapter. I had to purchase the valve for the tank separately to get the adapter, but it comes with a 1/4" tube outlet. I then took the valve off the adapter and used the valve from the upgrade kit to work with my tank. Very confusing, but bottom line is it would be nice if APEC offered a 3/8" upgrade kit that worked with the 14 gallon tank without having to buy other parts. The second issue, which is Amazon/APECs fault - the upgrade kit was supposed to come with a 3/8" to 1/4" tube adapter. This is needed to adapt to the 1/4" tube interface on the faucet. Instead it came with a 1/4" to 1/4" union. So I had to go to Lowe's and buy the adapter. One other note, the tank came with a dent in the corner. Not sure who's fault that is, but it does not seem to affect performance so I am living with it rather that navigate the return process. However, despite these issues, I'm pretty happy with the system. I was worried that stepping the tube diameter down to 1/4" at the faucet would impact the flow rate, but it seems to have little effect. The flow is good and I have plenty of volume. I'd recommend the system, just be make sure you have all the parts and be prepared to make a trip to the hardware store if needed. ... show more

    • Nice boost to system volume
Style: Storage Tank
Most RO systems come with 1-1/2 gallon bladder tanks, so you cannot quickly fill anything bigger than about a half gallon or so. This puppy lets you fill a jug, a big pot - lots of volume - before it’s flow rate drops off.
