Review: Difficult to setup but useable. - I have no idea what is the difference with the HYR270 aside from the flash switch. Very difficult to setup. I tried many times but there is always a leak since the rubber fit does not fit properly. I actually have to glue the rubber to the receiving hole. And made hude customize just to properly align and stabilize the device attaching to the tube. I glued it as well to make it steady.

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. ## Customer Reviews ### ⭐⭐⭐ Difficult to setup but useable. *by A***. on 29 June 2021* I have no idea what is the difference with the HYR270 aside from the flash switch.

The full flush works perfectly. Did all the adjustment on bleue tab and green tab, nothing will make small flush works unless holding 3 to 4 seconds. ## 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.hk/products/253669075-danco-next-hydroright-universal-water-saving-total-toilet-repair-kit](https://www.desertcart.hk/products/253669075-danco-next-hydroright-universal-water-saving-total-toilet-repair-kit) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-09-29*
