as for the RODI unit, did you backflush it? is there a restricting valve for the waste water on the unit that's fully closed?

 WOW!, I'm from ontario, we consider that PURE water here, i would be ashamed to flush the toilet.
my TDS is 8 after a 1 micron particle filter, a 5 micron carbon block, a catalytic GAC canister, a 1 micron carbon block and a spectapure RO membrane.
