RO/DI unit

[jerthunter]

I have recently begun searching for a good RO unit and I found what appears to me to be a good deal on a 6 stage RO/DI unit that is rated for 125 gpd. Now this is by far much more then I need but it is being sold for much less then any other units I can find.
The name on the unit is dvoneb aqua, does anyone know if this is a good unit?
Also the information from the unit claims that it can be used for both drinking and aquarium use, however I know it is not good to drink DI and I don't see anywhere on the unit that it has a seperate tap of before the IX, Does anyone have one of these and know if they have a tap off for drinking water?
Thanks

Not familiar with that unit, but my one RODI has a separate tap off along with a pressure tank/resivoir to tap off just RO water for drinking and the other tap is off the DI unit........checkout that infamous web based auction site for these items and key in on the filtermaster or something like that.......for a 6 stage ro/DI with dual taps and pressure tank

A membrane with a lower gpd rateing will filter water better. The slower it flows the cleaner it gets.

Well I actually found this unit listed on that infamous web based auction site. The unit I am looking at does not come with a pressure tank however it appears to be exactly the same as a more expensive model with the tank being the only exception.
I can see what you are saying about a lower flow rate being better however this one claims to get impurities down to 20 ppm after the RO unit which seems pretty alright to me.

Does anyone have any recommendations for good RO units? They all seem relatively easy to install. Is it important to get one with a tank? Hmm, I guess that is it.

I dunno...From what a lot of palces that carry the units told me is the only difference is in how much water it makes in a day........If a membrane is designed for 75 gal at x amaount of reject annd a TDS of X and you also have a 100 gpd membrane desinged for more water production and it delivers the same TDS and reject how can a lower GPD membrane filter better.........If you think you can simply put in a 75GPD mem in a 100 and get better water your kidding yourself, all you'll get in return is less water produced.....not better filtered water.

If you intend to tap off it and have a separate faucet/valve for dringking water then its nice to have a tank as it will supply water out of the faucet under the tanks precharge pressure, so it aids in filling up a glass or contianer a bit quicker plus you have a minimal amount already on hand stored under pressure...Not really needed if your just filling up jugs for top offs.

Hey,
I have the unit you are talking about. I love it!!! It reduces my impurities to anywhere from 24 to 8ppm depending on the time of day and how much the water lines are being used. It is perfectly fine to drink DI water. I consulted the water guys here on base and they described the entire process and it made sense when they were talking about it. Your body wont get the minerals that are added to bottled water but you will still get your fluid intake from the water. I have been drinking about half a gallon of my RO/DI water a day and have never felt better. It is a good buy for $100.

Hey Airforce,
Whats the brand of the RO unit that you have? I am gonna need one with a garden hose connector so I was looking at the Spectrapure. Whats a pressure box for? Since I havent set my tank up yet, I need one that is capable of filling up a 125gal and also for top offs after that. What gpd would be best?
THanks :thinking:

 

[airforceb2]

dvoneb is the brand. I had to get a hose connector from Lowes for $2 because I have the unit in my laundry room and just split the washer cold water supply. Mine was advertised as a 100GPD but really only produces around 75. This would be efficient for your 125. I would imagine a pressure box would be the same thing as a pressure tank. It just allows you to store up to 3 gallons of filtered water so you don't have to wait on it to filter small amounts.

Hi,
I actually own a DVONEB 6 Stage RO DI unit and initially it worked great but it does not make the amount of water it advertised. I have the 75gal/day unit but it actually made only about 40gal/day and now it makes alot less. I've replaced the filters but still it doesn't produce what it specified. I have pretty high pressure in my water pipes but evidently i might need to install an extra pump to increase the pressure. That means more money and more work.
But the unit does create good RO water with everything at zero. I can even dump the water in without adding any additional conditioners.
The unit is less expensive so you get the best bang for the buck. To recommend another unit, I'd go or the Kent RO DI system. It works great but its only a 3-4 stage system and more expensive. Good luck. You can contact me at jnvu@pacbell.net if you have additional questions.

i have the one you are talking about mine is rate 100gpd it was easy to hook up i also have one tank that i have hooked up but i dont use it i also hooked mine up to my shower head in my spare bathroom i got that ideal from another reefer on here my unit had set up for a few months and it get my water from 146ppm to 2 and 1 ppm so i like it if you get it pm me and i can show you pic of how i hooked mine up

Temperature can make a big difference to output to, I hear. Have you tried the bucket trick for warming up the intake water into the unit?

 

[bamack2]

this is how i hooked it up to the shower head only thing left is the waste water tubing and the good water tubing you can pm me for pic of the whole thing if you like
Ok i changed my shower head end out here is what i have now cost me about 3.50 at HD

beware that brass can put off free copper ions into the water. RO/DI water will remove a lot of the copper, however you are making your unit work a lot more.

 

[bamack2]

thanks Snake for the head up on that

hi guys, i've been eyeballing the dvoneb and water general units. I see lots of people have these problems with flow but no one ver posts their home psi. 40psi can seem like alot but it's not much really. nearly all Ro units work best from 65-100 psi. you can buy a cheap tester at lowes or home depot for like 5 bucks in the sprinkler aisle. It hooks to hose threaded spigots and tells you your psi.
I mean I'm trying to ascertain if these are really that bad or if everyone just has low psi, but no one ever bothers to test it. so does anyone actually know their psi?

Make sure you have good water pressure or RO units don't work.

Hello Everyone. I've read quite a bit of people that have purchased Dvoneb RO/DI filters are in need of replacements. Dvoneb is actually the generic name. The ---- seller Dvoneb tried to brand his own name. I've owned a unit for about 3 years now and its working great. That is because the actual manufacturer is WaterGeneral Mfg. Co. made in the USA.
I had been looking over my original files on the manuals that was sent to me by Dvoneb, I've attached the link to their website below for replacements.

Good luck!
