Is this a good RO/DI unit?

What a riot. I just sent you a PM saying the setup pics were good on that web page.

I have the same unit, only it's a 5-stage rather than 6.
Great Price, and it seems to work well (I still need to get a TDS meter).
It sure beats lugging jugs back from the store though.
I set mine up so that it dispenses RO water from the tap (the little spigot that comes with the kit) and then I plumbed an extra fitting under the sink connected to a plastic tube that I can run to the sink to fill the jugs with RO/DI.
You sure can't beat the price... I think I paid $109 for my setup about 6 months ago. :columbo:
Though now that I look again, my kit came with the 4-gallon reservoir tank... you may want to look into purchasing one of those as well... RO/DI takes 'forever' to filter through, almost the equivalent of watching grass grow.
I do 8-gallon changes on my 55g tank, and it usually takes a little over 2 hours to get all the water filtered, even with the 4-gallon tank.
HTH.

Looks like a deal to me. 5 micron sediment filter. Standard sized cartridges. I normally prefer 75 gpd membranes over 100 gpd membranes but that's just my personal preference.

I use an Aqua-Safe Canada unit that I bought via ebay. It works great and they answered all my questions before and after the purchase. Only drawback is the canisters are white and not clear. Just a matter of prefence.
The only thing that caught my eye was the 5-micron sediment filter. I'm not certain how much of a difference it would make, but we've always used 1 micron sediment filters.
I also found it amusing that they say "replace after 12 months" for the sediment & carbon block filters. Ummm, wouldn't this depend on how many g of water have gone through the system? We replace ours about every-other month. ;-)
Not sure what "normal water pressure" is. Our water pressure is probably a bit on the low side, as it hits the RO/DI after a whole house filtration system. We get about 30-40 gpd out of a 100gpd membrane.
HTH,

Usually the GPD rating is based on a 75 psi rating. My 100 GPD unit does about 75 GPD at 64 psi. Also, the clear housings allow you to see if your filters need changing. The cost of white housings is 1/2 that of the clear housings. Also, the extra carbon filter after the DI is mainly for looks. Most sediment filters need to be changed every 500-800 gallons, depending on your water quality. And the carbon is usually exhausted after about 800 gallons. The 5 micron filter will cause the most expensive part of your system, the RO membrane, to wear out quicker. Remember, once you wet the RO membrane, make sure you keep water hooked up to it so it stays wet. If you dont, the membrane will become damaged. All that said, the unit seems like a descent deal, however, I would look for one with clear housings.

The amount produced by the RO/DI also depends on water temperature... the cooler the water the less it produces.
Our tap water is about 60 degrees in the wintertime, so production goes down accordingly.
Luckily we're on city water, so I don't have much sediment to filter out, mostly nitrates and phosphates (which help prevent corrosion in pipes).
I really need to get a TDS meter though... that would probably help rather than all this guesstimation I'm doing.

Yes... forgot to mention that... Our water temp is pretty stable here in Florida.... usually about 74 to 76 degrees. I always forget that some people live in places that get really cold.

looks like a ok unit.i agree with above though on getting the clear canisters and like the fact that ours has a small fawcett mounted on the sink.it also said no pressure tank,mine has one.good or bad? i dont know.i would check around a little more.we got ours from e-bay too.[hbwatersystems.com]ours is a 5 stage 75gpd unit.

Clear housings won't tell you that you need to change your filters, a TDS meter will. IMO

I just realized that I kinda sounded argumentative in my last post. I just wanted to point out that a TDS meter should be used to determine when filters need to be changed.
