The convertors were installed on both an American Standard (front handle) and Kohler (side handle)toilets. Installation per the included instructions was simple and only took about 10 minutes per toilet. After only some minor adjustments, both convertors function as advertised. The shower head that comes with the kit is simple to install and offers a few settings, although it may be a little too low flow for some people. The kits do not include the J-tube assembly, shown as optional in the instructions. This is a great feature included with another convertor sold by MJSI. I tried to get information from MJSI about ordering a couple of J-tubes for the convertors, but was unable to get a responce from them via email or by telephone. Overall I would recommend the HYS420 for anyone wanting to save money on their water bill. The installation is simple, too bad getting customer service is not. ### ⭐⭐⭐⭐ 4.0 out of 5 stars This won't work if you have a 3" valve *by M***S on Reviewed in the United States on February 6, 2012* I love the theory behind this product. It seems very well made, certainly better than other flush valves that I have used. Alas, it will NOT work if you have a 3" opening between your tank and your commode. I didn't see that anywhere on this page and it really needs to be here. I was excited about the product and wish the folks who are making it success. That being said, the 3" caveat is noted on the product web site but not here. It needs to be here, too. Is someone listening? As far as the manufacturer goes, can you create a similar product for 3" openings? My rating is based on my assumption that the product will work, the quality of the manufacture (as far as I was able to ascertain), the great quality of the instructions and kit assembly, and the good reviews as far as support. If it worked as I expected it to, I'd have given it a 5. ### ⭐⭐⭐ 3.0 out of 5 stars the fill in valve sticks *by O***1 on Reviewed in the United States on October 16, 2011* Overall the product is good but the fill valve has some problems. When the water is flushed the float sticks and it does not drop and as a result the tank does not fill up. I need to shake it so that it works. It does not happen all the time but it happens occasionally. It is annoying. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/38806614-bluesource-hys420-hydrosmart-water-conservation-kit-by-mjsi](https://www.desertcart.sk/products/38806614-bluesource-hys420-hydrosmart-water-conservation-kit-by-mjsi) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-07-28*
