Perhaps this constant on/off and the resulting TDS creep is why Im eating through DI resin so quickly too... (besides the idiotic accidental reversal of 1 and 5 micron carbon blocks 6 months ago or so)
hmm.. this float switch thing sounds similar to my DIY ATO except wired differently.. or with a different relay..
im racking my brain on how the switches would have to be done, or which kind of relay used to make this work... Do you mind sharing the parts you used to put it together, or a source for a completed setup?
You could DIY it for a little less I would imagine but I got mine on sale.
You really do not want or need two carbon blocks if you use high quality filters. You will get much more useful life and better membrane protection out of a single 0.5 micron absolute rated sediment filter and a single 0.5 micron 20,000 gallon carbon block then use that extra empty canister as another 10" vertical refillable DI filter. Note long time companies like Spectrapure, Buckeye Field Supply and PurelyH2o only use a single carbon. Two carbons goes back decades whe ncarbon technology was not as advanced as today. $5 in parts and 10 minutes will replumb the empty cartridge to a dual DI along with your existing one for longer DI life and better water.
