Is zero tds possible with RO only?

[lastlight]

Lance and JDigital that is GROSS. I've taken slight offense guys...just a casual warning but please keep my threads on-topic and clean.

Yeah on my last tank I ran the ro/di straight to a float valve in my tank and battled algae like you wouldn't believe. Bet it was the creep. I have to install a float into my water-change top tank after I can pull the ro/di line out of the display.

I actually cut the autoshutoff stuff out of the unit as they are cheap and always fail. I bought a backup but the creep issue drove me to get rid of it altogether and besides the float valve in my reservoir I also have it plumbed with an emergency drain. I am buying an electronic solenoid and putting it on a timer to run for a set period of time nightly. Right now it's on full-manual. Meaning I gotta keep an eye on it!

The unit had a flush kit but since my old unit didn't have a flow restrictor I didn't even know what it was. When I had issues getting the thing to not dump waste water like a banshee I realized what I had removed and put it back in place. I need to add a new valve in to do flushes still.
