Just know that for every gallon of water you make, there are like 3 gallons of wasted water. Other than that, change filters fairly regularly and enjoy!

I posted some tips a few months back during a previous sale here. If you have any specific questions, ask away!

**Edit: This one is cheaper, but doesn't have the booster pump included in the previous deal (which isn't really needed unless you have low water pressure like a well system.) A permeate pump (different than a booster pump) might be a worthwhile add-on if you want faster water production and less waste though.

The cartridges are leaking, I had to spend another 200$ for plumber to clean the water and fix under sink

could be installer error,
the o-ring was pinched during install, or
the o-ring was not lubed during install, or
cartridge is not tight enough (hand tight is not enough).

with time, all cartridge housing will start to crack and need to be replace.
transparent cartridge housing have a life span of 5 years or so.
non-transparent cartridge housing have a life span of 10 years or so.

always check the inside of the cartridge housing for cracks when replacing filter.

google "RO filter waste water ratio"

its basic physics really.
it requires a lot of pressure to force liquid from one side of a filter to the other.
the pressure from city water has enough energy to filter about 1 gal clean and 4 gal waste.

really good and expensive system,
get to 1 gal clean to 1 gal waste with pumps, special filters, and tons of electricity.

here's a good read:
https://premieresales.com/how-muc...sis-waste/

go to "Amount of water sent to drain per one gallon of RO water produced"
has a table comparing different RO system's performance with time.

just something to get your feet wet.

BrightTank8484 already covered a source, but this is basic physics of how an RO membrane works. The actual RO 'filter' is just a long coiled semi-permeable membrane that uses water pressure to force pure water through and out to the storage tank. The brine that is left behind contains all of the 'filtered' material, in a now concentrated water solution, and is flushed down the drain. Typical RO systems will usually be somewhere in the 1:4-1:2 ratio of RO water to brine, depending on input pressure, discharge backpressure on the RO membrane, and the actual RO membrane construction itself.
If you're worried about water waste/consumption, you could plumb your brine hose to a storage tank and use it for watering vegetation, or use a booster pump and put it back into your hot water pipes for use in showers, etc.

Did anyone read the negative reviews? When you read things like this, do you really want to pass all your drinking water through this device:

There are 1:1 ro systems, is this not one of them? (I know there are, i just am not sure if this is that type of system, want to confirm).

I use RO for cooking, hot water makers, and humidifiers... anything that has potential of mineral buildup, if anyonr is looking for a good reason to get one.

From what i've read and known, the waste is so high in ec, it is not usable for plants. Everything else yeah! Just not that.

Theres people who use the waste as runoff right into ground and it killed the grass.

There are very few consumer marketed 1:1 systems, and I would find it very difficult to believe this is one of them.

Oh, definitely don't use it for watering grass or houseplants; I meant more for larger shrubbery or trees when diluted back down with tap water.

I have a Permeate pump it makes it 1:1 cost was about 30$(currently $50) it uses no electricity and it also fills the tank to higher pressure.

The "waste" water I ran to a 55gal drum and use for watering vegetable garden.

I would avoid these no name brands with shill posters and bought reviews.

APEC is a really good brand for RO system.. of course its not $100 either.
I have installed 6 of their systems. and only had 1 issue.. and it was amazon's fault.
APEC did send me as a 1 time curtesy the missing part from amazon's "warehouse deal"

Amazon's warehouse deal items are considered used with no warranty (didnt know that at the time).

If you dont like changing the filters, you can buy special model with quick connect filters.. no wrench and fiddling needed.
