Buy if you want to waste your money.
Had it for just over a month I plugged it in and the resin started coming out. Of the the cartridges broke and customer service is no help all the money I spent for the dic-20 is a waste. Not buying again and they lost a customer. Read more
Spotless System works great for My RV!
The system works great for rinsing my RV! We have a large RV and with this system i don't have to worry about water spots on the finish. We live in the country and have well water for our water supply. Mineral spots have always been a problem for washing cars and our RV. The system leaves no spots and makes it so much easier to clean and it's a walk away after we rinse our vehicles. Read more

Really good! 120 ppm -> 0 ppm @ 5 GPM
Really good! My ppm is 120. These will take that to 0 ppm at 5 GPM. That's impressive. Read more
Don’t turn water pressure on too much
I have ordered four of these this past year. They seem to last for about six to seven good washes. I have learned that a gallon per minute flow meter, kept at 2.5 gallons per minute along with an RV in line water filter helps a lot and makes it work much better Read more
