Will this RO/DI unit hook to faucet?

QuAcKeR · 10-08-2003, 01:37 AM

I'm ready to buy an RO/DI unit, but I need to be sure I can just hook it up to the faucet in the kitchen when I'm ready to make water, and unhook it and store it out of the way when I'm done. I can't plumb it into the pipes or anything. I only have a 10 gallon tank, so making a 5 gallon bucket of water every week or so will be fine with me if this method works. I just can't do a permanent (or semi-permanent) install where I currently live.

Can the unit at the link below be hooked up to a regular tap? Also, does this look like a decent RO/DI unit? The price seems more than right: Link to RO/DI unit on ebay

Thanks!

You can connect any RO to a faucet. You may have to pick up some plumbing fittings at HD but it's not a big deal.

If I'm reading correctly it appears three of the stages are carbon filters. I don't know why anyone would need three.

is it a RO or a DI unit? they are not the same, if you use an RO unit, then you do not want to leave it unhooked from any water for more than a few dys, the internal filter media (which is not carbon) WILL clump up and you will have to replace it( happened once before to our lab).

after looking at the Ebay pics, it looks like just a DI unit, you will have to keep a close eye on your carbon cart. and your prefilter cart., a nice way to have a back up is to have a large plastic carboy that you can keep 10 plus gallons on hand.

There is a list of parts and I think it includes a DI cartridge.
If it has more than a carbon cartridge, it shouldn't hurt.
Make sure there is a sediment cartridge too. If not, you can always replace one carbon block for a sediment cartridge.
It looks pretty bulky, but it's a good price.

Here's a picture of the faucet adaptor. It's pretty cheap, BTW.

Well it's good to know that RO/DI units can be fitted to a faucet that easily.

I am worried about tims' reply that it should be kept hooked up to water or else it will clump up.

If anyone has any other suggestions on where they got a good unit I'm definitely open to suggestions. This particular one does mention both RO and DI, but yes, it does seem bulkier than others I've seen people post pics of on here.

From what I understand, the ro'di untis can be portable, and there is no detriment to the filters if they are flushed.

tims · 10-08-2003, 01:17 PM

i did not mean to worry you. if you just store the unit if it is an RO you will have problems with the filters. if it is a DI unit then you should be fine with no running it for longer time peroides.
you can store DI and ro water in a plastic container for a long periode of time with out losing the quaility of water.

I don't understand what you are saying. Is it that if the R/O's sit dry for more than a few days the filters will fall a part or that it must be run everyfew days to keep the filters good. I am conserned because I have an R/O and I don't have to top off all that often so the R/O is only run once a week.

Toadfish · 10-08-2003, 03:08 PM

Your probbly fine as long as you flush the unit.

Renzema · 10-08-2003, 04:06 PM

would it be better to run it every couple of days for a few minutes?

tims · 10-08-2003, 04:09 PM

yes just as toadfish said,
as long as you do run or flush the system with in a week you should be fine. if you are storing the unit for a long while the main filter for an RO unit may no longer be good. ( the ion filter would need to be exchanged)
but if you do use it or just flush the system you should be fine

tims · 10-08-2003, 04:14 PM

you can run it every few days if you want, i would look into the man. handbook that came with the unit.
the unit i have has an atuo flush cycle of about 24 hrs. the unit can go up to a week before any of the filters need to be changed if it does not flush. i keep 60 liters of ro water on hand at all times, so if i run into problems i have a back up.
sorry to cause any worry guys....... that was not my intent.

No big deal I just ordered a float valve so now it will run everyday so no worries. The kent float vavle should be here on Friday.

why is this RODI unit from SpectraPure almost $400, when this one from Aqua-Safe is only $100. Especially in light of these comments that brand is not that important because they all use the same/similar filters anyway. And given that the Aqua-Safe is a 6 stage while the Spectra-Pure is only 5 stage.

The only differences I can tell is that the Spectra-Pure has a built in TDS meter (but i'd rather have a hand held one anyway) and a water pressure meter (probably a good idea). Either way, i can't believe that the TDS meter and pressure gaugue are worth an extra $300!

PS. I copied this from my original post
here after i realized that more people would probably see it if i posted it in General Discussion.
