I have been looking into getting an RO
unit. I have heard that for every gallon of good water, you dump 4 gallons in the drain. Is that true. If you loose that much water to the water treatment plant for what you get, is it really cost efficient when you factor what the water from the town costs.
How cost efficient is it really. Right now I can buy RO
water from a local supplier for 1.99 for 5 gallons. Any thoughts on this?
