The permafit silicone seal is also chlorine and chemical resistant and will not warp. - ELIMINATES TOILET LEAKS: Eliminates common leaky toilet problems due to a worn-out flapper, handle or faulty flapper chain. - HASSLE-FREE INSTALLATION: Drop-in installation without tools in 5 to 10 minutes - tank removal not required. This has an adjustable height of 11-13.8 inches. - TOILET FLUSH VALVE COMPATIBILITY: The Dual Flush Converter works with standard 2 in. flush valves and requires a 10-inch minimum clearance from highest point of the flush valve opening to the inside of the tank lid. NOT COMPATIBLE WITH MANSFIELD TOILETS. The HYR451T combines two products that together will increase your toilet's efficiency: HYR271 Dual Flush Converter and HC630 HydroClean fill valve. - DUAL-FLUSH LIGHT-TOUCH LEVER UNIQUE SPLIT HANDLE DESIGN: The short center lever is the Quick Flush setting that uses significantly lower water volumes for liquids and paper – this setting is needed 4 out of 5 times. The second complete push lever at end is the Full Flush that uses the normal amount of water for solids. - IMPORTANT INSTALLATION TIP: Do not remove overflow tube and flush valve from toilet tank; the Dual Flush Converter is a replacement to the existing flapper; slide the blue silicone dome gasket down the overflow tube, seating the gasket into the flush valve. - DETECTS LEAKS & WATER ADJUSTMENT CALIBRATION: Detects leaks and signals when a leak is found. The Total Repair Kit also can be calibrated to adjust the exact amount of water needed which saves water. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00B9BNGU0 | | Best Sellers Rank | #22,029 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #56 in Toilet Flush Valves | | Brand | Next by Danco | | Brand Name | Next by Danco | | Color | White | | Customer Reviews | 4.0 out of 5 stars 2,249 Reviews | | Global Trade Identification Number | 00188670000381 | | Included Components | Dual Flush Valve, Fill Valve, Handle | | Installation Method | Floor Mounted | | Installation Type | Floor Mounted | | Item Dimensions D x W x H | 3"D x 3"W x 10.5"H | | Item Type Name | HyrdroRight Universal Water-Saving Toilet Repair Kit with Dual Flush Valve | | Item Weight | 1.5 pounds | | Manufacturer | Danco, Inc | | Manufacturer Part Number | HYR451T | | Material | Plastic | | Material Type | Plastic | | Model Number | HYR451T | | Number of Items | 1 | | Number of Packs | 1 | | Product Dimensions | 3"D x 3"W x 10.5"H | | Seat Material | Plastic | | Shape | Round | | UPC | 188670000381 | | Unit Count | 1 Count | ## Product Details - **Brand:** Next by Danco - **Color:** White - **Item Weight:** 1.5 pounds - **Material:** Plastic - **Product Dimensions:** 3"D x 3"W x 10.5"H ## Images ![Danco HYR451T HyrdroRight Universal Water-Saving Toilet Repair Kit with Dual Flush Valve, Lever Handle, White, HYR451T - Image 1](https://m.media-amazon.com/images/I/71oidoL0WIL.jpg) ![Danco HYR451T HyrdroRight Universal Water-Saving Toilet Repair Kit with Dual Flush Valve, Lever Handle, White, HYR451T - Image 2](https://m.media-amazon.com/images/I/61Z9kWy9wSL.jpg) ![Danco HYR451T HyrdroRight Universal Water-Saving Toilet Repair Kit with Dual Flush Valve, Lever Handle, White, HYR451T - Image 3](https://m.media-amazon.com/images/I/71GN0NlTAuL.jpg) ![Danco HYR451T HyrdroRight Universal Water-Saving Toilet Repair Kit with Dual Flush Valve, Lever Handle, White, HYR451T - Image 4](https://m.media-amazon.com/images/I/71P--xRkQPL.jpg) ![Danco HYR451T HyrdroRight Universal Water-Saving Toilet Repair Kit with Dual Flush Valve, Lever Handle, White, HYR451T - Image 5](https://m.media-amazon.com/images/I/718VA4xRAFL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: This this work on a sloped flapper?** A: I installed this in my girlfriend's toilet, and it has a sloped drain. I thought I needed the plastic spacer to attach the drain valve assembly, but it did not seal. After realizing there is a rubber bushing/spacer, I replaced the plastic shim with the rubber and that stopped the leaking. So far this proves to be holding. **Q: Will this work in any standard toilet?** A: This also doesn’t fit older side flush Pegasus toilets. You need at least three inches clearance between the center of the handle mounting hole and the riser tube for the fill valve. The handle assembly for this kit is very bulky and will interfere with the float if there isn’t much room. **Q: Does this fit a kohler ellison toilet as a replacment part? is there any thing else i need?** A: As long as the lower rubber seal fits the tank drain. Don’t place too much pressured on unit, or will deform seal, and the tank will drain. **Q: anyone tried this on a mansfield? sounds like i need to convert to flapper before install** A: This kit requires the flapper and the overflow value to be separate, though there is NO mention of this anywhere that I can see. You have to attach the big white piece to the overflow value, and the blue thing at the bottom sits where the flapper was. On a Mansfield toilet, there's no way to remove the plastic piece that serves as the combined flapper/overflow valve without disassembling, so there is no way to insert this thing. I considered trying to replace the weird combo piece with a separated assembly, but then I decided to just buy a Niagara toilet and save myself the headache. Mansfield toilets are dumb. ## Frequently Bought Together - Danco HYR451T HyrdroRight Universal Water-Saving Toilet Repair Kit with Dual Flush Valve, Lever Handle, White, HYR451T - Danco HYR460 HyrdroRight Water-Saving Toilet Tank Repair Kit with Dual Flush Valve, Includes Dual Push Btton Handle in Chrome --- ## 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/15778457-danco-hyr451t-hyrdroright-universal-water-saving-toilet-repair-kit-dual](https://www.desertcart.jp/products/15778457-danco-hyr451t-hyrdroright-universal-water-saving-toilet-repair-kit-dual) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-17*
