I have a hose hooked to the DI side and the other side capped. The monitor on the unit reads O ppm. My independent meter reads 275 and it leaves spots on my car. The company's response is that they want video of the unit not working. My advice is to set your $500 on fire and save the aggravation. ## Features - Integrated bypass. - Clean & Integrated Bypass Feature: Effortlessly switch between filtration and bypass modes with a seamlessly integrated bypass system, conserving expensive resin and ensuring high-quality filtered water is reserved for the final rinse. - Material: Stainless Steel - Purification method: Deionization - Capacity: 300.0 gallons - Included components: 20" wall system, TDS meter, stainless hose, wrench, nozzle, 2 filter cartridges ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DBJ7KD1D | | Best Sellers Rank | #23,161 in Automotive ( See Top 100 in Automotive ) #33 in Car Washing Applicators | | Brand | CR Spotless Water Systems | | Brand Name | CR Spotless Water Systems | | Capacity | 300 Gallons | | Customer Reviews | 3.8 out of 5 stars 25 Reviews | | Included Components | Filter, Inlet Hose, Outlet Hose, Instruction Manual | | Installation Type | Wall Mount | | Item Dimensions L x W x H | 15"L x 15"W x 25"H | | Manufacturer | Spotless Water Systems. | | Material | Plastic | | Material Type | Plastic | | Maximum Flow Rate | 2.5 Gallons Per Minute | | Model Name | DIW-20B. | | Model Number | DIW-20B. | | Other Special Features of the Product | Reduce TDS, Rust Resistant | | Part Number | DIW-20B. | | Power Source | Solar Powered | | Product Dimensions | 15"L x 15"W x 25"H | | Purification Method | Deionization | | Special Feature | Reduce TDS , Rust Resistant | | Supported Water TDS Level Maximum (PPM) | 2000 | | UPC | 810102010278 653958490685 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** CR Spotless Water Systems - **Capacity:** 300 Gallons - **Included Components:** Filter, Inlet Hose, Outlet Hose, Instruction Manual - **Installation Type:** Wall Mount - **Material:** Stainless Steel - **Maximum Flow Rate:** 2.5 Gallons Per Minute - **Model Name:** DIW-20B. - **Power Source:** Solar Powered - **Product Dimensions:** 15"L x 15"W x 25"H - **Purification Method:** Deionization ## Images ![Spotless Water Systems - DIW-20B, W/Integrated Bypass | Simple Window, Solar Panel, RV & Car Wash System, Works for All Vehicles, Motorcycles, Bikes, Boats, Planes, Yachts, Towel Drying Eliminated - Image 1](https://m.media-amazon.com/images/I/71ecUJnxZpL.jpg) ![Spotless Water Systems - DIW-20B, W/Integrated Bypass | Simple Window, Solar Panel, RV & Car Wash System, Works for All Vehicles, Motorcycles, Bikes, Boats, Planes, Yachts, Towel Drying Eliminated - Image 2](https://m.media-amazon.com/images/I/71Y2wfDu88L.jpg) ![Spotless Water Systems - DIW-20B, W/Integrated Bypass | Simple Window, Solar Panel, RV & Car Wash System, Works for All Vehicles, Motorcycles, Bikes, Boats, Planes, Yachts, Towel Drying Eliminated - Image 3](https://m.media-amazon.com/images/I/61dNylcxGXL.jpg) ![Spotless Water Systems - DIW-20B, W/Integrated Bypass | Simple Window, Solar Panel, RV & Car Wash System, Works for All Vehicles, Motorcycles, Bikes, Boats, Planes, Yachts, Towel Drying Eliminated - Image 4](https://m.media-amazon.com/images/I/41Hi0VyCgNL.jpg) ![Spotless Water Systems - DIW-20B, W/Integrated Bypass | Simple Window, Solar Panel, RV & Car Wash System, Works for All Vehicles, Motorcycles, Bikes, Boats, Planes, Yachts, Towel Drying Eliminated - Image 5](https://m.media-amazon.com/images/I/71XYdX2VsNL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great *by D***G on June 18, 2025* Works great ### ⭐ Has never worked *by S***E on April 26, 2026* This has never worked from the moment I hooked it up.
