I have a pump that stays in my brute RO container and even after two weeks, my TDS still reads 0-1. </span>

Yea, I don't rinse it when going from one to the other. I'm getting a QuietOne 1200 from Sam when they come in and will run it outside the tubs so only the hose will go in when I'm pumping instead of the whole pump.

I just ordered from this ebay site. The handheld unit was the cheapest price around and the guy is local so I got in the mail in 2 days without any added shipping costs above the standard. The link is;

We got some good water in GA. A friend in Arazonnam tap is 950 TDS after his RO 28 TDS.

I tested a bottled water also 19 TDS. I'd bet their is some bottled watert higher than our tap.

Have you fix this problem yet?
235ppm TDS should be reduced to no higher than 10-12 ppm with the average 75 GPD RO. After the DI it should be 0 ppm

 

[jefft]

Well water north of Macon read 77.

 

[ouling]

Not always a 0 tds after the DI. This is what I use now.

9 stage quad DI. 0TDS Also I use a very conservative TDS meter which always reads a bit higher. I do an 110v conductivity test instead.

You guys don't know how lucky we have it here, in DFW area were I moved from a couple years ago 300 TDS was low!!! Having said that our low TDS is still loaded with phosphates (like off the chart on a Salifert test) so RODI still very important!

Call them and ask, they usually will as long as you sound professional. But not all labs test TDS everyday.

Newnan is always between 51 and 57.

Guess that shows how either the TDS or the TDS meters can vary, eh?

Your waste water should be higher than your tap water. If not your RO membrane has a issue.

I'm not sure, b/c the waste water line is still after the sediment and carbon prefilter.

That very ture. With that low of a tds a good carbon... could very well lower your tds 5 or 6 TDS.

 

[glxtrix]

how is it possible to have a higher ppm from waste than from tap??? Where does it magically gain waste?
