It works great! *by R***E on January 12, 2025* Not much to say, other than it fixed poor flushing on a Flushmate toilet in about two minutes start to finish. ### ⭐⭐⭐⭐⭐ Great replacement part. *by K***N on February 5, 2026* This fixed my problem.

Exactly what I needed! *by J***E on January 11, 2017* This little valve was exactly what I needed to fix our Flushmate pressurized toilet! Saving us $ from calling a plumber. A super simple fix, anyone can do it! Just look up "Toubleshooting Flushmate" on YouTube, or take a look at the photo i included. The duckbill valve gets set inside the cap labeled "D" and then you just screw the cap back on. VERY IMPORTANT, only hand tighten the cap back on. Don't use any tools. Over-tightening the cap can damage the duckbill valve or cause it to bend and not suck in air properly. The valve was (and should be) very inexpensive. Dont overpay for a replacement! ## Frequently Bought Together - FLM B108288 Flushmate Duckbill valve - Flushmate BU100505-KIT Upper Supply Kit for Pressure-Assisted Toilet Systems - Compatible with 503, 503H, 504 Series, Fits Flushmate, Kohler, Gerber, Includes Upper Supply Assembly & Hose Clamp - OEM Original Replacement For Sloan C-100500-K Flushmate Cartridge/PowerFlush Toilet Piston Cartridge Parts for Use with 500, 501, 501A, 501B, 503, and 504 Series Flushmate Tank System (1) --- ## 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.pt/products/19616102-flm-b108288-flushmate-duckbill-valve](https://www.desertcart.pt/products/19616102-flm-b108288-flushmate-duckbill-valve) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-05-17*
