I bought a Fluidmaster 5403 3-Inch flapper in November 2021. In March 2026 4 1/2 years later it had developed a small blister on its O-ring and would not seal correctly. Typical wear I assumed. As I was ordering another one I saw it had a ten year warranty. After ordering the new one I went to the Fluidmaster web page and found the warranty information. I filled in and sent the warranty form and 45 minutes later I got an email with a FedEx tracking number saying a replacement part was on its way. The new part got here in 3 days. This flapper fits perfectly - took on a minute to install - and works great. Not only is this a great part that does the job the customer services was bonkers good. From now own Fluidmaster will be used for all my toilet needs. The people at Fluidmaster shall sit amongst the chosen. ### ⭐⭐⭐⭐⭐ Works well, stops the leak *by on Reviewed in Canada 15 June 2026* Works well, although do wish I could find just the gasket as thats the part the is the issue after awhile ## Frequently Bought Together - Fluidmaster 5403 3-Inch Water Saving Long Life Toilet Flapper - Fluidmaster 400H-002 Performax Universal Toilet Fill Valve High Performance Tank and Bowl Water Control, 1-Pack, Multicolor - Korky 100BP Ultra High Performance Flapper Fits Most Toilets - Long Lasting Rubber - Easy to Install - Made in USA, Small, Red,1 Pack --- ## 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.sg/products/266643999-fluidmaster-5403-universal-water-saving-long-life-toilet-flapper-3](https://www.desertcart.sg/products/266643999-fluidmaster-5403-universal-water-saving-long-life-toilet-flapper-3) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-09*
