Car washes and smaller drug stores often have cheap RO water for sale, seen signs around town before for $1 or $2 for 5 gallons. Not sure how good the quality is and I know car washes don't have high quality RO water but I'm thinking it's way better than the alternative.

With these 7 stage Ro/Di units can you disconnect 1 or 2 of the 2 di stages i am sure you dont need 3 stages of di resin working, or will it last just as long as using each one seperate? also he has 1 for $101. buy now
