Alrighty, we'll see what TDS I get without the DI.
did you verify your tds meter with some distilled water?
No, not yet. Still in my PJs, LOL.
I'm not sure how to give feedback to this seller... Normally, I'd give negative feedback, but in this case it's between neutral or positive. Yes, there were broken parts. That sometimes happens in shipping, it's inevitable. Granted, their packing was far from the best, but still. The reason I'm conflicted is because I've now contacted them twice, on two different days, regarding two different issues, and both times they've had replacement parts on the way with priority postage the very same day. They're doing their absolute best to fix the issues. They never even questioned me about the broken parts, either. The DI canister lid, for example, could well have been broken by me over-tightening the fitting that screws into it (I didn't, I was very careful about it), but they didn't even mention it. I told them the part was broken and they said "must have crack during shipping. Will ship out today." You really can't beat that kind of post-sale support...
times like those I have simply left no feedback... but that is a call you got to make.
they may have never seen it (drop shipped by a 3rd party), may have been some flunky doing the shipping that day, or who knows... do-do does happen to the best of us
Yeah, I don't know. We'll see.
Now, if I measure the TDS right out of the membrane, I'm reading 4ppm. If I measure at the spigot, with the tank closed, about 19ppm. If I measure at the spigot with the tank open, about 12ppm. That last bit is sort of strange, being I emptied the tank of all of the water from last night (the water which had been through the DI stage) and let it refill with water from today, no DI stage. So the water from the tank SHOULD be the same TDS as the water that comes right from the unit to the spigot. I don't know. It seems my brine ratio has gone up (the permeate output is much slower) so I'm going to go remeasure that and I'll remeasure water right before and after the membrane again.
We'll get this hammered out, LOL.

Before membrane: 63ppm.
After membrane: 7ppm.
Still at about a 2.2:1 ratio. Seems that everything is just moving slower than yesterday, the pump even seems to be cycling slower. Maybe I'm imagining it. I need to get to Lowes and get that gauge...

Mmmm, might've just pinpointed a possible suspect... directly out of the carbon post filter is 29ppm.
EDIT: Can I try having the water go straight from the permeate out of the PP to the tank? Bypassing the carbon post filter and DI stages completely?
other then the variance in TDS, the rejection ratio is sounding much better
not sure why your tds would be doing what its doing, logic dictates an issue with the measurements.... or we could still have some trash purging from the system...
Sometimes I tell my students it is a case of "FM"
(freaking magic LOL)
Ideally, I would hope to see your rejection ratio hit 90% or better and a brine rate closer to 4:1 (which may happen with a little use)
The carbon post filter is producing "fines", it should clear up and is of no concern... this is characteristic of GAC units,
bypass for a test if you wish, its main purpose is to remove any VOC that may gassed off by the tank bladder
yep, and edited reply :-)
Haha, excellent. By bypassing the post filter, will it leave anything of any harmful nature to plants? I do not intend to use it as drinking water, just for the plants. Also, are those "fines" of any danger to the plants? Or is it just carbon? I can't imagine carbon dust would be dangerous to the plants, but then, I can't imagine it would conduct electricity and register on a TDS meter (isn't that how they work?).
shouldnt be an issue either way mate....
and omg RO/DI makes the best sun tea and coffee
fresh ground Kona beans and RO/DI :-)
