No, but look at your buildup ratio. You need to replace all your filters, because they all pick up sediment and eventually wear out. It is just that the waste water expells what isn't filtered...
YOu don't need to refilter the RO water from the stage.
Stage one
In from source OUT to stage two
Stage two
In from Stage one OUT to stage three
WHere as teh filtered water from stage on and two, go to your faucet.

but that only applies to the ro ALL water goes through your carbon canister and your sed canisters in my case I have a 5 micron then a 1 micron (5 microns are cheaper than 1's so I use them as a buffer) the way the canisters are built no water can bipass theses filters. also whats consintrating the water sorry I cant spell better

I talking as clean water....so because bottled water is RO water...tap water is full of crap put in and you pay your goverenment to monitor and say is acceptable for you to drink
It doesn't matter if the bottled water is from the city, a spring, or a glacier. Bottled water is still the same from each source

Does the RO water go through your carbon filters or the other way around?

So if I whip out my trusty TDS meter, bottled water will always test cleaner than tap?
FWIW, I get 25 ppm TDS out of my tap.

stage 1: 1 micron sediment
stage 2: 5 micron carbon
stage 3: .6 micron carbon
stage 4: RO membrane
stage 5: DI
why is your 5 micron after your 1 micron?

Ok...I'll try a different way to explain this.
Water enters in for sediments, then carbon filtration.
It would do this, because chlorine...added by your city government will destroy your membranes so that has to be taken out first.
Then teh water passes over the filter. PRESSURE, pushes the water through the membrane. Water left over after this process goes to the second filter (which will contain a higher level of sediments, because SOME water has passed through the filter) The water that has passed the first stage is called the brine,which flows to the second stage and tries to filter out more water under pressure through the membrane.
The water that has passed through your membrane in both 1st and 2nd stage goes your supply tank (where your good water is stored)
The water that is waste water, would be the water that has gone through your 2 stage filters and carry stuff that isn't filtered out. ((or hasn't passed through the membrane)) That is called the brine. Usually more concentrated then the start of the process

I think I understand what you're saying.
With our RODI filters, the water that was not pushed through the RO membrane is not put through a second membrane. That's what we call our waste water. The part I put in red does not exist on our filters.

Water left over after this process goes to the second filter wrong water left over after this prosses is the rejected water in debate(which will contain a higher level of sediments, because SOME water has passed through the filter) The water that has passed the first stage is called the brine,which flows to the second stage and tries to filter out more water under pressure through the membrane. your second stage is your carbon and should be under no greater pressure that regular tap water
The water that has passed through your membrane in both 1st and 2nd stage goes your supply tank (where your good water is stored)why would your water go through your membrane more than once?
The water that is waste water, would be the water that has gone through your 2 stage filters and carry stuff that isn't filtered out. ((or hasn't passed through the membrane)) That is called the brine. Usually more concentrated then the start of the process
why is it more concentrated than regular tap? the sediments and carbon filters have already pulled some thigngs out of the water? check out where I quoted you Ive answerd in red

That may be true.
You see I have a dual stage RO on my system. All that does is put emphisis on waste and efficeicy. Cuts down waste water and allows more GPH. Also, I worked on systems that were multi-stage for...dare I say...bottling water.
All your sediment filters do, is target certian sediement ratings. Now I see why sign guy was confused, by my analagy
And yes, you go bigger to smaller.
I would not dare touch the waste water even on my neighbors dog...because he'll probably pea in my yard anyway. Because if any of your filtration failed you would get a very high dose of stuff in your water glass.
