We did, the tds meter was reading 2tds out of the faucet and about the same coming out of the membrane and 0 coming out of my DI chamber.
My dual tds meter reads-14 out of the faucet, 4- out of the membrane, 0 out of the DI chamber.
To clarify a little more into detail. I have Well water, Well water has high CO2 levels which will exhaust DI resin rapidly. So i have made a De-Gassing chamber to resolve this. I have a line coming out of the Membrane that would go into the DI chamber, i have it going into a ACE hardware 32gal container. I let it sit in there for atleast 24hrs with a airstone to drive out the CO2. Then i use a maxijet to pump water through the DI chamber into my 32gallon brute W/C container.
Last nite i did not have any water in the de-gassing container as i had just pump it all into my brute container a few days prior in preparation of doing another W/C.
So when we tested the brute container full RODI water that had been heated to 77F and had a small powerhead for circulation, it read 350-360tds. Our test was to use the maxijet pump to pump that 350tds water back through the DI chamber to see if my recently bought DI resin was already exhausted. We were getting 160tds out of the DI chamber that was reading 350tds.
Without much thought, we agreed that it was the maxijet pumping too much water through the DI resin too fast and pushing debris out of the DI resin into my water, resulting in a high TDS reading.
I am now making new water from the membrane into the de-gassing container which never has had salt in it. I will have results from this in a few hours.
Sorry for the long post, this is why i would rather explain this setup in person as its easier to explain. And im sure i didnt do a very good job explaining it well enough for everyone to understand.
Thanks
