RO Unit on a well

As a matter of fact I never filtered enough. I never ran a post di then. Big mistake as the high alk. of the well water, which a di removes, often screwed up my levels when mixed with Instant Ocean salt.

No soft water was used for human consumption, as it was passed through the ro before going to the fridge and sink. Pure soft water was teed to the rest of the house.

I am stilll confused. If your water comes from the well, then to the water softener and finally to your RO unit all your water has been softened. Right? That was the very first thing that happened to the water.

The softening process removes all the hard minerals from the water so somewhere along the line those minerals would have to be put back in the water in order for it to no longer be soft.
Perhaps softeners do that? Maybe they put exceptable levels back in the water. I wouldn't think so as water straight from a softener is not recommended for consumption. This is due to the low mineral levels.

The RO unit won't put anything back in the water, it's nothing but a pre-filter, RO membrane (super tight filter) and carbon.

So by my figuring you end up with super filtered soft water, that has been treated with carbon.

Like I said I am no expert though. LOL
