I don't know, been wondering this myself.

I think you have to install it into the plumbing itself, so you can ether have it come out the faucet or to a barrel, but i have no idea...
 
i own the 3 stage 24gpd and its a decent unit for the cost. They have a fitting attached to the inlet line that screws right to the faucet. The only thing you need to do with this installation is some teflon tape, because its not a snug fit otherwise.

If you didnt want one of them, then you could look into a specra pure, which cost a bit more, captive purity is also another good unit. My favorite units would be ones from the filter guys.

use is very simple, screw in the piece to a sink not being used and turn on the faucet. Be sure to run if for an hour without collectin that water.

if you want to plump it in line with your cold water supply, you will need to do some shopping, find a saddle valve for that size hose, connect it and attach that to your copper water line. This should be done if you intend the unit to be "permanently"
 
oh so i can just attach it to my sink and then remove it when I want to. The r/o water would come out of the faucet right?
 
They also make little faucet things for RO specifically, they look like soap dispensers and sit next to the sink by the little extension hose sprayer thing.
 
those attachments are only if you have a storage tank.

yes it will screw right into the faucet, heres how it works:

you unscrew the finish tip from the faucet, attach the adapter if needed, teflon tape the part that the fitting on the hose would screw onto to ensure a solid fit and no leaking. turn on the faucet and your good to go. If you are not intending to use the filter for a while, it would be advised to remove the TFC membrane and place it in a zip lock bag, and place that in the freezer to preserve the membrane. If it sits in water for around a month or longer, they can start to deteriorate, thus being useless.

are you on well (town) water or on city water?? This will determine wheater you actually need an RO pump or not. Most city systems will have adequate pressure and you will be fine. On well water, deff. get a pump.
 
we are on a well, but we have pretty good water pressure, a little less than town.

I think I will try the 24 gallons per day one.

Sweetang any thoughts?
 
well it woks for me lol. Any basic model RO unit is going to perform the basic functions. They come with a TFC member to help purify down to 99%, a 1 micron sediment block to catch all the larger things, and a carbon block to help with any nitrate, nitrite, ammonia, and chlorine/chloramine absorbtion.

If i were you, i would invest in a system with a pressure guage, because RO units are more effective at around 60-65psi and i dont know any well system that can keep up with this pressure consistently while the shower, toilet, sinks, dishwashers etc are running. the pressure guage will help you track your PSI as its running through out the day. Give it a go and see how it works, you can always add a pump down the road.

Also last bit of advise, after you get your tank fully switched to RO water and you not making as much, consider purchasing there add on DI unit, This is really going to help fully purfiy the water, and you would be surprised as to how much more pure your water will be.

let me know if you have any other questions, and ill see what i can do.
