Envig CarShine 713 Deionization Car Wash System, 500 Gallon 0 PPM Water @ TDS 60 PPM, Bypass Valve and Inline TDS Meter, Spotless DI Mobile Detailing

Bought this because I was getting tired of water spots, and having to hurry up and dry the motorhome. Now just wash with regular water, and turn the bypass valve to rinse, and no more water spots or trying to dry the coach before the sun dries it. It is actually a little smaller than I expected, but will work out great for storage purposes, as we are full time and storage is limited. Add this to the list of things that I should have bought a long time ago, add a nice small pressure washer and you're all set.

So far everything works as it should. I will say I was a bit confused at trying to get the top off, but I contacted Envig and it was explained the entire top (cap, handle, and meter) all twist off together. Once I had that information, I filled the tank with resin put it back together and was ready to clean my solar panels. Solid tank with good parts.
