I first got RO system from Costco that had a mini bladder inside the unit to make it smaller. It's flow rate was very slow. Then I read that you need larger tubing so the next system I got was from home master that has 3/8" tubing while most systems have 1/4". Mine also has the UV light

I am not sure I understand how tankless works when the process for RO takes times. I know water drop makes tankless but I don't have personal experience but my friend has and that unit is still quite large as it has 3 cartridges on the front of it.

Which 3/8" system did you get? I've had a difficult time finding a system that uses 3/8" throughout the system.

It's hard to always find this detail. Look up home master on Amazon. That's one I use at present and has good flow. They are a local company based out of Arizona with pretty good support

Reverse osmosis tips. Only use dow filmtec membranes. Everything else is worse and not worth savinga few bucks. Amazon sells the film tecs for 30.00. Ispring is a decent starter brand for kits. Tank and the autoshut off valve are the weakest link. Might switch them out ASAP. Bulk Reef Supply is your best friend for RO. They dont sell garbage. Pumps are silly IMO. I get 98-99% rejection without it. If you do get a pump, this one is crap. Get a flowtec or shurflo. The pressure tank, is most likely the first thing that breaks though, and it's very hard to get an American tank. USA Water Systems used to sell American tanks, but now it seems you have to buy the whole 500.00 us system to get the us tank. Pretty solid warranty though.

you just explained physics to slickdealers

Thinking about getting an under sink RO filtering system for a house we are moving to. It has well water.
Can someone please recommend a good under sink RO system for well water?

Deal is for tank options. Tankless is better, specially if placing under sink

Which would you recommend?

do you have a recommendation for both the tankless option and to remineralize the water?

I have the Frizzlife PD600 and have been very happy with it for 3 years now. Minimal waste, replacement filters aren't overly expensive and are readily available, and it was very easy to setup and maintain.

Medical science (SCIENCE) will tell you that your body will regulate the acidity of your body no matter what Gwyneth Paltrow or anyone else on the internet tells you. There is nothing you can ingest that will change the pH of your body as long as you lungs and kidneys are functioning properly. Well that is within reason and not deadly. As far as calcium, magnesium, and potassium, well, they are commonly known as electrolytes and most people consume way more than they need with drinks and supplements. This is causing an increase in kidney stones! Also your liver will detoxify your body not things that make you cry on the toilet. So take the information however you want, but just remember. Even though you think it makes sense and feels good if SCIENCE tells you that you are wrong. YOU ARE WRONG.

Not disagreeing with you, just saying that my docs will tell you my lungs and kidneys are operating normally. But they cannot explain this with current science:

We see marketing claims that alkaline water will neutralize the overall body, and it's often purported as a way of neutralizing stomach acid. These claims are pseudoscience, and promote the false idea that the acidic environment of the stomach that is so vital to digestion need to be eliminated - claims that often sound logical enough to convince some end-consumers.

But you can't look at instances of erroneous claims as evidence that the underlying product itself has no application. Not everybody who is utilizing alkaline water is doing so because they believe it can "alkalize the entire body". It is a very effective as a targeted tool to treat conditions like LPR that results in a build up of pepsin in the upper esophageal tract, serving to neutralize the acids that should not be there, but are, and are causing damage to tissue in the region - with the implication that you are also taking concrete steps to address the underlying dysfunction itself.

The cool thing about Alkaline water is it's strictly speaking a generic term that refers to a water with alkaline properties, which no company (and their erroneous marketing campaigns) has a monopoly on. I produce my own Alkaline water in house at a fraction of the cost of any marketable product, and my utilization of the product is based on my understanding of the underlying chemical science, not any marketing team trying to convince me nonsense about the health benefits they claim their product can offer.

Alkaline water is so lightly Alkaline it has no impact on acids in the esophagus. You should look into what it means to have a PH of 7.5 or 8 when mixed with liquid of a PH of 3 and understand how the chemistry works.
We all make Alkaline water when we add a pinch of baking soda to it.

I grow Carnivorous plants. For watering them you want as close to distilled water as you can get. Otherwise the mineral content builds up and kills the plants. I got my RO system from a failed aquarium store. I got the system and 2 years of filters for less than $150. Just keep an eye out and deals will pop up.

I use ours for this in addition to our humidifiers, steam mop, and baby bottle washer to prevent mineral build up.

How do these plants (in natural environment) get this pure, distilled water on which to thrive?

They live in bogs where the water flowing through peat get stripped of most of its minerals. It is less about the minerals in the water momentarily, and more about as the water evaporates, the minerals remain behind in container gardening, so it is good to add as few as possible to avoid build up.
