The entire process should take around 20 minutes. ### ⭐⭐⭐⭐ Cheap OEM Fix For a Big Issue - If You Can Install it *by C***N on December 12, 2023* I bought these after both of my 20 years old Kohler Raphael toilets started leaking -at the same time!- After so many years submerged in water, the gasket had expanded to the point it started to make cracks on the weakened plastic tabs. In one toilet, the Flush Valve just came off completely from its socket, rendering the toilet unusable. These are exactly the same parts that came with the toilets and should last for another 20 years (there is hope) Now onto the installation, the hard part. This piece has a very tight fit with the tank's wall, thanks to its massive gasket, and there is only one way to push it into it and then turn it to reach its final position. This could be really hard to do, needing a lot of trial and error an decent force to push the piece in. It can be really frustrating and you can damage the plastic tabs if not careful. Whomever in Kohler thought this was a good design was probably fired a long time ago. Or maybe not as it lasted for 20 years. Who knows Anyway. I'm not a fan of the freezing method some other reviewers explain here. These gaskets are not designed to be frozen, and in my view freezing them may alter their chemical composition, reducing its useful life. Also, they may break if not treated carefully when frozen as they have lost all its flexibility. Freezing them turns them into hard pieces of fragile plastic, and once they expand back to its original form, even very small cracks will become bigger, and the gasket less flexible (NASA learned this the hard way, back in the 80s) An alternative to freezing it and what Kohler somehow recommends -even if not directly, they just say to "wet it"- is to soak them in water for a few minutes. This will in fact expand the gasket a bit, which you would think is the exact opposite of what's needed, but what it does the most is to soften it. This gasket has some capacity to absorb water, its seal is provided in part via expansion under water. Once the gasket is soft enough, it will be easier to compress and just a decent amount of pressure and turn will install it easily. Think about a kitchen sponge: hard when dry, soft when wet. I learned this while installing it in the first toilet. After a few unsuccessful tries I noticed that after the gasket became wetter, it was easier to compress and I eventually installed it. So for the second toilet I accelerated this process by leaving the gasket in water for a few minutes. The installation was fairly easy and I did it at the first try, no issues whatsoever ## Frequently Bought Together - KOHLER 471147 Genuine Part Flush Valve Assembly Kit, 0.75 x 3.25 x 10.00 inches - KOHLER GENUINE PART GP1068030 FILL VALVE FOR ONE-PIECE TOILETS --- ## 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.vu/products/15833056-471147-genuine-part-flush-valve-assembly-kit-0-75-x](https://www.desertcart.vu/products/15833056-471147-genuine-part-flush-valve-assembly-kit-0-75-x) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-12*
