[hypoxia]

Thanks Rob & Steve.  I haven't watched any videos but have seen the CR Spotless and Spotless Water Systems DIW20 which look exactly like two Pentair 20" Big Blue housings and refillable inserts with Anion in one & Cation in the other.  I have a local supplier for everything related to water who suggested just one housing with the mixed bed anion/cation resin for portability and should be good for around 150 gallons  I can travel with a spare preloaded insert or just a bag of resin, those inserts also have a sediment filter inside. The resin refill for each cartridge is relatively inexpensive when purchased by the 1 cubic foot bag, probably around $25 or less.  I can add another housing later if needed.

I have a gas powered pressure washer and water softener to use with the DI here but need to get an electric pressure washer for travelling, suggestions on models?
