I use a hydrologic micRO-75 for my plants. Been using it for about 8 months and it's still coming out at 0ppm. I have it hooked up to a 20 gal res with a float valve that I refill as needed. Don't even need to watch it just turn it on and check later to turn it off. Trying to pump RO water on demand becomes a huge chore. If you setup a res bucket for it, it can last weeks. I even have a smaller 5 gallon one that worked great. During heavy flowering I'm filling it weekly but early on only once or twice a month at most.
As other have mentioned zero water isn't RO and will probably not work well for horticulture needs long term or in a larger scale.

Thanks go people. I live out in the middle of nowhere. I want an RO system but my countertops are marble. I would have to drill the hole for the extra water faucet that comes with the RO system. My wife looked at me and laughed when I brought it up. That was a big NO when it comes to drilling into the countertop. The tabletop RO system wouldn’t work for my needs. I would wait a while to get a gallon from it. That’s why I was curious about the zero water. Seems like that’s the only option for now. Our water is county water that’s trucked in and unloaded into a massive tank at the front of my neighborhood. Tap water is a little more costly because of this. Guess that’s what I get for living in a neighborhood that’s away from everything. Up’s and downs I guess.. Thanks everyone for the replies
Well shoot. I was going to say my RO system is hidden behind the toilet and taps into that water line. The tub is close enough to fill the water bucket and run the waste into a second container. No counter top drilling necessary. We use the waste for lawn/garden/etc....
Then I read further. Yeah. If you've got to truck in water the amount of waste water might cost you enough to not make it worth doing.
If you haven't bought a nutrient line yet, the JRPeters/Jacks offer water testing and nutrient advice to work with it. You do have to send in your sample and some $$ for them to run and analyze it. However, it sounds like they have a nutrient line adustment for tap/hard water. Might be worth a peek.

You can get an RV water filter on amazon for $20 that attaches to the end of your hose. I've been using one for years for filling my hot tub, it makes balancing the chemicals afterwards a lot easier and the water stays clearer. It removes a lot of contaminates, including claims to remove chlorine.
I have and used the zero filter. It does get the ppm to zero but my water is so bad after a 2 weeks the filter is bad. Ppms jump to 50 then slowly up from there. It also comes with a free ppm meter. i haut quit using it cause the filters are spendy and truthfully i dont care so much to spend all that time doing it.
No kidding. Checking Amazon now. Thanks for that!!!!
As long as you get an RO built for the right purpose there is no need for any drilling or even installation. Everything they sell at lowes or Home Depot will be what you described.
what you want is something like this:
Amazon product ASIN B01N7DH9ZT
It hooks up to any hose or laundry sink, no installation necessary. All you need a a place for the drain water to go. This was just one of the first hits on Amazon, there are other brands that are only $150ish for a one stage RO.
Those under sink units are not built for the kind of use or volume that you need for growing anyway. Something like the Hydrologic is what you want.
Good luck!

If you pay for trucked water, you have a problem. Any RO system wastes a lot more water than they purify. I have delivered water as well, so RO is not tolerable due to the waste. I collect snow or stream water as a result. My delivered water is over 300 EC, the limit suggested by Cocoforcannabis.com.
Another option for you is to have your water tested, and get advice on how to make it work by choosing the right nute package. Some of them are designed specifically to deal with higher ppm tap water, but to get it right you need to test and then get advice from the nute manufacturer. I recommend Jack's as one good alternative here. They respond to requests for help, make excellent nutes for a fraction of the cost of liquid alternatives, and have mixes tailored specifically for tap/well water. If you go this route, you may want to check to see that your delivered water is consistent between deliveries, especially seasonally. There would be little point configuring your nutes for water delivered in October, only to find out that the water delivered later in your grow was very different.
One final note, if you supplier or municipality has done some testing, you may be able to get test data without paying for it. Good luck with your grow.
