Review: Love it - I just installed the DIW-20B and LOVE it. Absolutely no water spots! My TDS is 278 and I had spots all over so had to towel dry it all the time, not this time! Thanks again. Review: Water leaks - Water leaks non stop from the middle of the system when DI water is on. I installed this for my mobile detailing van and every day or two days I have to vacuum the floors because it gets flooded with water. I've been using it for about a month and a half and I decided that I would rather stop using it and deal with regular tap water.The water comes out with 0 ppm as advertised so that's the only reason why it's not a 1 star review. ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DBJ8HM1S | | Brand | CR Spotless Water Systems | | Capacity | 200 gallons | | Container Type | Bottle | | Customer Reviews | 4.2 out of 5 stars 132 Reviews | | Included Components | 20" wall system, TDS meter, stainless hose, wrench, nozzle, 2 filter cartridges | | Included components | 20" wall system, TDS meter, stainless hose, wrench, nozzle, 2 filter cartridges | | Item Dimensions L x W x H | 38.1L x 38.1W x 63.5H centimetres | | Manufacturer | Spotless Water Systems. | | Manufacturer Part Number | DI-120B. | | Material | Stainless Steel | | Material Type | Stainless Steel | | Model Name | DI-120B. | | Model Number | DI-120B. | | Package information | Bottle | | Power Source | Corded Electric | | Product dimensions | 38.1L x 38.1W x 63.5H centimetres | | Purification Method | Deionization | | UPC | 810102010261 | ## Product Details - **Brand:** CR Spotless Water Systems - **Capacity:** 200 gallons - **Included components:** 20" wall system, TDS meter, stainless hose, wrench, nozzle, 2 filter cartridges - **Material:** Stainless Steel - **Model name:** DI-120B. - **Package information:** Bottle - **Power source:** Corded Electric - **Product dimensions:** 38.1L x 38.1W x 63.5H centimetres - **Purification method:** Deionization - **UPC:** 810102010261 ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/71fTNBeEfbL.jpg) ![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 - Image 2](https://m.media-amazon.com/images/I/71C6aYVrt8L.jpg) ![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 - Image 3](https://m.media-amazon.com/images/I/61igqyXHi-L.jpg) ![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 - Image 4](https://m.media-amazon.com/images/I/71XYdX2VsNL.jpg) ![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 - Image 5](https://m.media-amazon.com/images/I/41Hi0VyCgNL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Love it *by A***R on 11 June 2026* I just installed the DIW-20B and LOVE it. Absolutely no water spots! My TDS is 278 and I had spots all over so had to towel dry it all the time, not this time! Thanks again. ### ⭐⭐ Water leaks *by W***. on 15 June 2026* Water leaks non stop from the middle of the system when DI water is on. I installed this for my mobile detailing van and every day or two days I have to vacuum the floors because it gets flooded with water. I've been using it for about a month and a half and I decided that I would rather stop using it and deal with regular tap water.The water comes out with 0 ppm as advertised so that's the only reason why it's not a 1 star review. ### ⭐⭐⭐⭐⭐ Solid build quality and beyond worth it for your wash station *by A***N on 11 October 2024* Echoing what all others have been saying for years, but this is a game changer. Doing the rinse with DI shaves off so much time in regular washes and not having to worry about chasing drips with a towel for hours is almost life-changing. I have low ~100PPM TDS muni water with hopes the resin will last and will likely be quick to get the rv-mods conversion to remove the need for the spotless cartridges, but we'll see how long this lasts as I lock down my optimal rinse time. ## Frequently Bought Together - Spotless Water Systems - DI-120B, W/Integrated Bypass | Simple Window, Solar Panel, RV & Car Wash System, Works for All Vehicles, Motorcycles, Bikes, Boats, Planes, Yachts, Towel Drying Eliminated - CR Spotless RC2-20 Replacement Cartridges For DIwith DIC-20 - CR Spotless R2-20 Refill Resin for DI-20 Systems, 1 Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/800041284-cr-spotless-water-systems-di-120b-simplest-rv-and-car](https://www.desertcart.jp/products/800041284-cr-spotless-water-systems-di-120b-simplest-rv-and-car) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-08*
