LiquaGen 4 Stage Reverse Osmosis and Deionization (RO/DI) Portable Space Saver Water Purification System | Water Filtration System for Aquarium Filter Processes + Manual Flush Valve (100 GPD)

First of all. Once it works, it's awesome. Does exactly what it says. RO'es some water down to 0 TDS. It's fairly compact, and does 50 gallons per day as stated. Got mine all set up in about 45 minutes in my basement off of the faucet. It connects like a regular hose would. You might need a Y connector if you plan on using the faucet or running water somewhere else. I was lucky and had a leftover one from outside. Will need to get another next year.The reason why I didn't give it 5 stars is because they say that it's air tested before they ship so that it won't leak when you hook up the water. Well mine definitely wasn't. I would understand if one of the connectors or tubes came undone, and just slide it back in place, but that wasn't the case. The entire 3rd filter tube's top was not fully rotated. Leaked TONS of water right away. So I had to take quite a few of the hoses undone to get the wrench tightener thing(that it came with) to tighten it all the way. There is no way that could have happened during shipping, the tubes would have turned or something.Anyways, great filter! For anyone using this for a fish tank. My water starts with a pH of about 7.8, after RO went down to 7.0. Starting TDS 125 down to 1 or zero. Will definitely help if your tap water has a high PH or too many dissolved solids.Quick reminder that not everyone needs to drink water with 0 dissolved solids. It's often healthy to drink water with minerals in it. Drinking this water will taste bland/kinda gross. I would only use this for drinking water if you have some other chemicals that are harmful to you in the tap water.

i purchased this for my aquariums idiot boy yes me tried a few different ways to hook this up not realizing there was a double washer in one of the fittings that came with it and hid the threaded fitting I've been looking for in every hardware store under the sun. ultimately i had to hard plumb the unit due to some leaks which i added an inline pressure gauge. im averaging about 5 gallons pure water to about 12 gallons waste water. I do have 1 huge request for this unit since it is painfully slow, make a 1/2 pvc pipe timer that can be hard plumbed into the unit. I told my wife to not shut the garage door i was testing the unit, she forgot and closed the door and of course the baby had me occupied and wouldn't go to sleep unless i laid down with her, when she finally passed out i got up walked by the closed garage door and forgot the unit was running till the next day. thankfully the waste water i plumbed to go into my pool no loss there since it was low and i needed to fill it. barley dented what i needed to put in. but the fresh filtered water side filled up the 5 gallon jug and overflowed for a about 12 hours, not much of a mess i'm guessing only a couple gallons ultimately over flowed so now i make sure to use an alarm before i turn that faucet on.

Product works great, no issues except attaching it to my faucet, but that was due to my faucet being cheap plastic.What really impressed me was their CS. My product did not come on time and whenever I tracked the package, it showed as "delayed" and would give a new delivery date. Finally, after 2 weeks of this I called all ready to chew some butt, but before I could get a good head of steam going the CS rep saw that it was lost in shipping and would send a new one through priority mail and upgrade it from the 75 to the 150 gpd. This was late on a Friday night and he said he would get it going and email me the new tracking # tonight.I did not get the tracking # so I called again on Monday morning. Talked to the same guy and he apologized because it was too late that night to get the order out so to make up for THAT, he threw in a free set of replacement canisters.A bit of a rough time, but they did right by me in the end. I could tell by the way they handled themselves that they are committed to making happy customers. Overall I'm impressed with the company, as for the product, it does the job as intended, can't really complain.

****One warning. Check your water pressure at home (device is about 5 bucks). If it's 40 or below you will need to request a low pressure membrane. I had to resolve this through the company after the fact because there is no way of knowing in the amazon description. The good news is that you don't have to buy the highest pressure model (150gph) since the low pressure membrane is only about 75gpd anyways. So if you're pressure is lower purchase the cheapest 75gpd unit and ask for low pressure membrane. I've been using this for maybe 6 months and it works very, very well. This is for fish tank purposes. The water measures zero nitrates. The price is awesome compared to similar units out there. I've been trying to measure the ratio and it does seem about 4-5 waste to 1 clean water. This device is versatile. You can take outside in the summer and work off outdoor hose connection if you choose. It can also be connected to inside faucet (as long as it's screw in diffuser). I had to buy an adaptor from home depot to make mine work but it's worth it. The best part about the purchase is that the company answers the phone (owner I think) and he took care of any issues immediately with no hassle whatsoever. I rate this company as top notch seller and would not hesitate to purchase from them again.

So this is a Great value for the money. BUT THE WATER FLOW IS SLOOOOOOOOOW! I mine it takes One and a half hrs or more to Fill up a 5gl Bucket. I’ve had mine for 3 years now its still at 0 and works grate just wish the water flow was better.. 4 stars only because of water flow.
