It has a one-year limited warranty. Constructed of brass. Review: Pretty straightforward installation but YouTube is your friend - The product exactly met my expectations and fixed my running toilet. My wife is happy so I am happy. I'm glad I spent some time watching YouTube videos showing exactly what is involved, I like to know exactly how to approach a project before I begin so I don't waste time solving problems others have already solved. That said, when the videos mentioned that getting the thing to click into place on inside of the tank was a little tough, they understated things considerably. There isn't a whole lot of room in there for big hands and I was unable to get it to click into place until I used a long flat-blade screwdriver as a lever to coerce it into place. Start to finish, including time to utter some cuss words and go to the garage to get that lever was about 15 minutes. Review: works as described for our low-profile kohler one-piece - the seal on the flush valve for our kohler one-piece low-profile san raphael toilet (k-3466) wore out and it seemed the tank hadn't been cleaned in a while, so rather than replacing just the seal we decided to clean out and flush the entire tank with a citric acid solution, then replace all of the tank components including the flush valve that we purchased from here. it is solid and well-built, we have no reason to suspect that it is some cheaply-made knockoff rather than an OEM part.. some people have mentioned that they've experienced issues with getting the valve to clamp onto the tank given the rigidity of the new seal.. i personally didn't have any issues, but others have had luck with soaking the seal by itself in warm water, then quickly compressing it using clamps (between two blocks, or books for example) and placing it into the freezer for 24hrs. what this allows you to do is keep the seal compressed so that you can place it back onto the flush valve and clamp it onto the tank without any resistance.. but act fast once you take the compressed seal out of the freezer, because it will revert back to its normal shape very quickly to ensure a proper seal. good luck! ## Features - Kohler Genuine Part - Constructed of Brass - Flush Valve Service Kit - Model number: 471123 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002C6ICMS | | Best Sellers Rank | #152,299 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #203 in Toilet Flush Valves | | Brand | Kohler | | Brand Name | Kohler | | Customer Reviews | 4.6 out of 5 stars 234 Reviews | | Exterior Finish | Brass | | Global Trade Identification Number | 00087206784767 | | Inlet Connection Size | 1.5 inches | | Item Dimensions | 14 x 3.5 x 2.5 inches | | Item Type Name | Flush Valve Kit | | Item Weight | 14.56 ounces | | Item dimensions L x W x H | 14 x 3.5 x 2.5 inches | | Manufacturer | Kohler | | Manufacturer Part Number | 471123 | | Material | Brass | | Material Type | Brass | | Model Number | 471123 | | Number of Items | 1 | | Number of Pieces | 1 | | Number of Ports | 1 | | Outlet Connection Size | 1.5 inches | | Outlet Connection Type | NPT | | Size | 14 x 3.5 x 2.5 inches | | Thread Size | 1.5 inches | | Thread Type | NPT | | UPC | 087206784767 | | Valve Type | flush valve | ## Product Details - **Brand:** Kohler - **Exterior Finish:** Brass - **Global Trade Identification Number:** 00087206784767 - **Inlet Connection Size:** 1.5 Inches - **Inlet Connection Type:** Threaded - **Item dimensions L x W x H:** 14 x 3.5 x 2.5 inches - **Material:** Brass - **Number of Ports:** 1 - **Outlet Connection Size:** 1.5 Inches - **Outlet Connection Type:** NPT ## Images ![Toilet Flush Valve Kit Genuine Replacement Part - Image 1](https://m.media-amazon.com/images/I/61rjcRML9BL.jpg) ## Questions & Answers **Q: does this come with the plastic circle wrench that helps take out the flush valve?** A: There was no wrench but I used a plastic dowel to remove the clips(there were no nuts) and the new one just snapped in. **Q: Will this fit 84679-AA Model 703?** A: NO **Q: does this come with the plastic circle wrench that helps take out the flush valve?** A: No it did not. However the old one was fairly easy to remove. And new one to install was went in ok as well. Just make sure the gasket is in the right spot. You can move valve up or down to make the gasket seal properly. **Q: Does it have round gray gasket or rectangular?** A: yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ Pretty straightforward installation but YouTube is your friend *by M***N on February 27, 2020* The product exactly met my expectations and fixed my running toilet.

The parts came on time and the installation went quite well. It should be noted that there was a fair amount of time required to completely drain the reservoir and clean out all the old debris. Installation did require clever use of a flashlight to confirm the alignment of the flush valve assembly and engage the retention clips. But when all was said and done, the job was done. That said, one may be tempted to merely replace the flapper on an old toilet but if the flapper is going bad, you can bet that the gasket is as well. Don't mess around our you might end up with, well, a mess. ## Frequently Bought Together - Toilet Flush Valve Kit - Kohler 1068031 Fill Valve - Trip Lever Service Kit, Polished Chrome --- ## 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.dk/products/32405414-toilet-flush-valve-kit-genuine-replacement-part](https://www.desertcart.dk/products/32405414-toilet-flush-valve-kit-genuine-replacement-part) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-11-12*
