If you look at the photo, you should be able figure out how these parts go together. Make sure all three ends are threaded.Ģ ea ¾” NPT short male double ended nipplesġ ea ¾ “ NPT to ¾” male hose thread fitting.Ģ ea ¾” NPT to ¾” female hose thread fitting. If you want to do this, buy the following.ġea ¾” NPT threaded T fitting. I did not want to unhook the soft water hose from the pressure washer and change to the DI system so I added a splitter so all I have to do is hook up one end to the water supply and using the shut off valve, select non treated water to wash and then shut off the non treated valve and then open the valve going to the DI filter. I had to drill from the NPT side using a ¼” drill bit to allow the probes to fully seat into the fitting.Ģ short sections of schedule 40 pvc pipe.ġea female slip to ¾” female hose thread fitting.ġea female slip to ¾” male hose thread fitting. These screw into the bushings above and the probes fit into these. Instead of the fittings I listed above to connect a garden hose to the unit get the following.Ģea pvc slip fit bushings with ½” female NPT to fit into the top of the T fittingĢea 1/4” female push to connect with male NPT fittings. If you want to add a TDS meter get the following. I even was able to add a TDS meter and still come just under half of what I would have paid buying a CR Spotless system.Ĥ.5 X 20” Filter housing (typically called a “Big Blue Filter Housing”)ĭI resin cartridge direct from CR Spotless, cheaper than buying a refillable cartridge and filling it with resin.Ģ short sections of ¾” schedule 40 pvc pipe.ġea ¾” female slip to ¾” female hose thread fitting.ġea ¾” female slip to ¾” male hose thread fitting. My setup uses a hose splitter with individual shut off valves so I can choose soft water out of my water softener or DI water. You don't have to dry the car, but I use a leaf blower to get most of the water off. I tried it out today and it works rather well. Switch to the DI system to do a final rinse. My method of washing is use soft water with a gas powered pressure washer to knock off as much of the dirt and grime as possible, hook up the foam cannon to apply the soap then wash with mitts. Using the calculator on the CR Spotless website, It's estimated that I will get roughly 30 rinses from it, not bad. I decided to use the system just to rinse, not for washing, so not to use up the DI resin up so fast. I was able to source parts at half the cost of the CR Spotless unit, which is a DI-120. The single 4.5X20" system costs roughly $300.00 and damned if I was going to pay that much. I decided to research component prices and see if I could build one cheaper. It uses a mixed bed DI resin to remove most of the TDS (total dissolved solids) in the water. Quite a while ago, I came across the CR Spotless system. All of you with dark colored cars know that water spots show up easily, even if you have a water softener, you still get some spots.
