CR Spotless Water Systems - DI-120B Simplest RV & Car Wash System with Bypass Valve, Rinse Works for All Vehicles, Motorcycles, Bikes, Boats, Planes, Yachts, Deionized Towel Drying Eliminated, 1 Pack

This makes washing cars so much easier! Being able to switch from regular water to filtered with just a turn of a handle is so easy. Not to mention the spotless drying. No water spots!

This unit did not work for me for 5 months. I called the company and got a real human, which was a pleasant surprise. They sent me some documentation that had not been included with my system when I got and I was able to get it working exactly as it should. It really does make a huge difference in time spent washing the car.

This exceeded my expectations. I have a black car that I was always chasing water runs on and that is no longer an issue. My PPM went from about 160 to 0. I no longer have to spend so much time drying. I truly get a spot free rinse now. Would absolutely recommend.

I was missing 2 parts that screw into the input and output of the unit, but bought them as home depot, so no problem there, but when I installed it and washed my car I noticed the TDS was at 224. Was supposed to be bascially ZERO, the unit comes with a TDS monitor, and I was told by a plumber that this much resin probably cleaned the first 3 gallons that wen though the unit, but after that I needed new resin already LOL, DONT BUY IT !!!

FANTASTIC PRODUCT & CUSTOMER SERVICE!! 10/10 would recommend!
