Pressurized Water Storage Tank - Reverse Osmosis Water Tank with Stainless Steel Connections and Ball Valve - Water Filtration System Storage Tank 6 Gal & appx. 3.6 Gal Usable Capacity (ROT-6-W)

Easy to setup. Bought the 10 gallon to upsize a 4.5 gallon. Very easy to swap out and then let it fill and drain 3 times before using. The extra capacity is exactly what we needed for a family of 5, and sometime a few guests.

I ended up running 2 of these tanks so I could get the capacity I need without losing as much under sink space. Would purchase again.

This is listed appx 6 gallons usable. This is dependent on incoming water pressure. I have a regulator on my home water line set at 70psi and after all night refill after the second flush of the new tank I measured the amount of RO water the thank holds at 70 psi fill pressure, which was 3.75 gallons. This is to be expected with these type of tanks. There is a diaphragm in the center with 8 psi of nitrogen or just air depending on the manufacture below and your incoming RO water on top. The incoming water pressure pushed the diaphragm down against the gas pressure. When you used the water the gas pushes the diaphragm up sending the water out the faucet. With the narrow tall shape I assume the diaphragm is closer to the top as it must be completely pushed up to the outlet when empty of water. The placement of the diaphragm (surmising) reduces the amount of water that the thank can hold compared to a short stout tank. This is fine for me, I needed the narrow tall tank to fit my space and it has more than doubled what the 3.x gallon tank could provide, which it replaced. If incoming water pressure is more than 70 psi (max is 100 for this tank) I would bet it holds closer to what is advertised. This was a simple swap with the existing tank and does everything it is supposed to do. Just keep the fact you will probably NOT get 6 gallons our of this tank especially if you are on a well or other low pressure system. Hope that helps set expectations and you are not disappointed.

Added the necessary capacity to RO system after factory tanks diaphragm's failed

I have bi ro unit that feeds my sink in the kitchen an fridge, Adlai have a tee so that I can fill bucket for my plants. Dose what it’s suppose to

great mega buffer for my RODI clean side since I sized it at 200% of my instantaneous need at any given time(1 gallon drink jug and possibly filtered water in 1 gallon jugs for projects) but the integrated feet for sitting are a bit small for making it stable on imperfect surfacesonce full it is very stable and feels like it can't explode or even get dented in normal use on the clean side of a RODI setupI am an idiot, I was just browsing again and noticed the durable plastic bit that seemed like a cap for the 1/4npt port is actually intended to become the stand for the tank after shipping and install, should have guessed since it is a very dense plastic you wouldn't waste as just packaging materialso far so good, it holds pressure very well through almost all of it's rated capacity and somehow is almost a stable pressure despite the fact that the pre-charge nitrogen MUST be reaching higher pressuresfirst visit to family so unknown if it is ok for a week but assuming it is still holding water when I get back, I can be confident in this part of my RODI filter setup, only really concerned over the input line bursting anyway or the plastic tank from another seller I use as a water hammer damper at 80psi when it says 60psi max, but that is always conservative ratings, it almost certainly has a burst rating 2-3x that

I have added a small RO system to my refrigerators ice maker. I needed a small tank to hold water and provide some pressure. This works great.It's a really tiny tank. I would only recommend it for small systems, like an ice maker. i don't think it would keep up with lots of drinking water.

Made of real 304 stainless. Unit does not have a port to add air.

Item was a perfect replacement
