So your RODI runs for short bursts to top off your system? Usually not a good idea due to TDS creep. RO systems work most efficiently when used in longer runs, not short 5 minute bursts. I know you guys on the coast have pretty low source TDS, so might not be an issue. I would never do that here with a source TDS in the range of 180. It takes a good 3 to 5 minutes to get the the RO output TDS down to 1 from 20 or more on initial start up. And if I ran that 20 TDS on start up through my DI stage with multiple short on/off cycles on a continuing basis, it wouldn't take long to exhaust the media. Without the DI stage I'd be adding unwanted TDS to my tank in pretty short order.
