I don't drink the water out of this, its for my fishtankI have a RO/DI systemi put this tank before the DI filter.when everything is empty, and the output is turned offit fills the tank with RO water.when i turn output on, it takes RO water from the tank and runs it though the DI filter (maybe to fast) I still get 0 TDS from the water.when i turn the output off (after i get 2 gallons, it really slows down to a trickle at 2 gallons, like just what the RO makes without the tank)Then the system fills the tank up so i can get a quick 2 gallons the next day.my fish tank uses 1-2 gallons of water for evaporation every day. my 50 GPD RO/DI system can get me enough extra water that i can do water changes if i let it pour water a few times a day.Perfect Size (would be nice to get 3 gallons out of it though)** Note, my first tank leaked water out of the valve Top (the turn off leaked, not the tank), on top of the pressure tank, replaced and working fine

Sometimes one tank just isn’t enough… especially for the impatient ones. My RO system is in a utility room behind the kitchen sink and that’s also where the 3.5-gallon tank is so the 1/4-inch line to the faucet is about 15-feet long. That means I have about 1.5-gallons in the tank and it flows very slowly out of the faucet so I’m one of those impatient people that prefers not to wait a long time for a cup of water to be filled and it’s too slow to really use it for much more than drinking. Adding another tank under the sink and/or increasing the water line to 3/8-inch were the choices but putting my smaller tank under the sink and this one in the utility room solved that slow running issue to the point where it’s almost twice as fast so no need to spend more on tubing and fittings to move up a size in the water line. I can now get enough water quickly enough to also use it in the coffee pot, my homemade wine and some cooking… though not all at the same time. with just this tank it took 14-seconds to fill a 16-ounce mug and after turning on my old smaller tank with it the time was cut in half to 7-seconds. The new tank is working fine but it would be nice if they added some packing material in the box because that’s the same box used for shipping and the tank is right up tight on the sides so it’s ripe for a dent or two. I looked at some other tanks but just getting the tank valve is worth about 6-bucks because many do not come with it. I filled it twice and drained it twice before I filled it again for use. My air compressor is in the garage so I’m glad I checked the pressure first before I let it fill for the first time because you can’t get an accurate reading on the bladder pressure when it’s full of water. This one, as was the one before it, did not have any air pressure in the tank so I have some doubts about that “Pre-pressurized between 7-10 psi” statement. I don’t mind putting some air in it but it begs the question of where did it go if both tanks were pressurized and should I be expecting it to bleed off in the near future? I knocked off two stars for the lack of pressure but otherwise I haven’t had any other issues yet. If you don’t have a means of checking the pressure and adding air to the tank you may find that after installing it you won’t have any water to the faucet. I just added a new pressure tank to my well in our cabin and the pressure was correct so I’m disappointed I have received two of this without air in the bladder. The RO system I installed a few months ago also came with the correct pressure. If you notice a decrease in the water flow at your faucet it may not be due to a filter(s) clogging but rather a drop in tank pressure and checking it first costs you nothing but time.The first tank… I tried to save 10-bucks and went used in like-new condition and it was returned the day after it was received. There were some major dings; it didn’t have any air pressure; it wouldn’t hold air long when it was added and the tank valve was missing the inner locking ring so it couldn’t be used. All these issues could have been present before it was shipped or several could have happened while in transit to me. There was a note on the tank valve bag that said it was received in that condition so the next one was brand new, is now in service and is the one reviewed.

These tanks are universal, it appears, so you can just use the hose adapter that comes with your reverse osmosis system. You don’t have to use the one that they send you. As you can see in the picture I left theirs as a spare part and used the one I had. Mine was a different size, so I couldn’t use theirs anyway. My system was from Costco, Pure Blue H20.

The new tank looked great, I checked the pressure and it was 5.5 PSI. Pumped it up to 7.5 PSI and swapped over my old shutoff using some Teflon tape - in about 1 minute. Hooked it up and I am blasting endless RO water again! So great, my last tank bladder burst so I could not get enough water to fill the coffee maker. Now it goes on and on and I have gallons of RO water again! Very happy and hydrated!!!

Works perfect with our current system. Be sure to adjust your PSI before turning on the water. The PSI will not be set correctly when shipped. Just an FYI.

Thankfully I had read up on these RO tanks when my 5 year old iSpring one broke (bad bladder) and I knew that there was a way to check and adjust the pressure/PSI of the tank. The replacement tank I received had only 3 PSI of pressure when the suggested PSI should be between 7-9 PSI of pressure. It's easy to check with a tire gage and can be filled with a compressor or bike pump but IMO it should leave the factory at the correct pressure. Low tank bladder pressure will affect how much water you can dispense before your RO faucet runs at a trickle. A properly pressurized tank should dispense 2-2.5 gallons before slowing down to a trickle. Installation was simple once I corrected the pressure in the tank.

I noticed a little sound once the tank was turned off, so I cycled the valve a few times to learn I had to back it away from the off position to totally turn the tank off. Other than the previous note, the tank is not too large but does hold enough water for standard family use (cooking, drinking).Note: you may fill a glass of water and the system turns on (running water - waste down drain) to refill the tank for 10 minutes. This may seam like a lot of water to produce RO but in reality your replenishing the tank volume that had been depleted not just what you used to fill the glass.

If you have an R/O system that is not producing water like it should, you probably have a ruptured bladder in your storage tank. This particular tank was used to replace a 7 year old failed bladder tank of a different brand. Replacement is simple and easy. The supplied shut off valve of this tank has an eighth inch fitting on it and my old tank is one quarter inch. I had to swap the old shut off valve to the new tank so it would fit my piping. The tank comes precharged with about 7 lbs of air pressure in it. I increased that to 10 psi. So far it has been flawless. We will see how long it lasts long term.

Great storage tank With excellent flow.

Easy install came pre-pressurized and worked great.
