ro or ro/di

The sticker is on the airtight plastic bag holding the blue membrane cartridge. I'm sure your three tanks is enough already. As long as your tds meter says 'zero', you should be good to go. You might get a drip here and there from the unit, but that'll go away in a day or two as it breaks in.

cool, guess i missed that membrane sticker.

so leaks do go away eventually? i thought i had em all zipped up yesterday but noticed this morning i've got an ultra slow leak coming from the DI canister that i just cannnot loose. ignore it and it will go away you say??

[jws444]

You too huh?
The ends of my DI chamber dripped quite a bit when the unit was priming. I went out and got some teflon tape and put some on both ends of the DI tube. It helped, but it was still dripping about once every 5 minutes. A day or two later, it went away and is bone dry now.

damn, it's still drippin there!! anyhow, that's not why i'm posting this time.

so i've had the as maximus running now for a few days and have tested my water with a tds meter. just caliberated it so should be accurate i got outta the tap a reading of 13 and out of the ro/di water 2. does this sound right to you guys?? is 13 justifiable reason to get this unit cause i caliberated this to a solution of 800! the differences between 13 and 2 seem pretty insignificant to me...then again thats why i ask anyone??

My hand-held TDS meter initally read 1ppm even when my RO/DI unit was brand new. I see 1ppm as my "0ppm". Maybe you should do the same with 2ppm? I can't imagine anything getting past a brand new RO/DI.

Also, it could be that our containers that we are holding the water we are testing are dirty.

Oh, and it's good you flushed the new RO because as Brad said there is a chemical in the membrane that needs to be flushed.

Teflon should seal up the threads but if not try a dab of silicone around the threads.

Hope that helps you out a little bit.

i've run quite a few tanks now...i just guess i was wondering if a tds reading of 13 outta the tap is really all that bad?

[Jack]

Well, not nearly as bad as Calgary's TDS reading but... yes

...beacause that 13ppm could be anything.

After time those minerals build up in your system with freshwater evaporation top-up, water changes, ect.

[jws444]

Yup, Jack is right. The 13ppm in the water can be anything. I get a reading of 15ppm at my house. I talk to folks back east and their water lines are around 100-200 ppm, so we're really luckly in YVR. It just means that we don't have to change our resins as often.

try running some ro/di directly into a glass and testing the tds, mine is usally 1 or 2 below what i read out of my storage container.
