Here's the latest chapter in my water struggle. I elevated things with the builder and were able to get some movement. In the meantime, my RO unit was roasted. After 1 week in use, the membrane was cooked and the DI resin exhausted which resulted in TDS readings around 60ppm.
However, I digress. We finally had these installed as a last ditch approach before digging a new hole in the ground. No one will be able to say I wasn't patient or open minded. Plus the well company told me there was no guarantee I would hit better water.
The good news is the pH out of the tap is now around 7.5. The bad news is for all the bad stuff these take out, they put twice as much "good stuff" back in, effectively doubling the TDS going into the RO/DI unit. Consequently, I will need more DI units in line.
