It is well made and look and feels high quality2. The detented adjustments allow a wide array fitment, and the detent positions hold very well3. The flapper is adjustable for the length of time the flapper stays open.. which is nice4. Easy installation... almost too easyNow... the primary reason for my review is the following5. The longest "flap open" setting of 10, leaves about 3 nches of water in the bowl, which made me concerned.. as this was the longest the flap could stay up ( 10 was Max)BUT6. I watched the actual bowl flush and it was a complete, full length flush..7. I confirmed this by leaving the tank cover off for three days, and the tank would have about 3 inches of water BUT still allowed a complete flushThis is a real water saver, as the flapper it replaced would drain down to about an inch..I was concerned that the flapper was closing too quickly to allow a full flush BUT it does allow a full flushGreat product ## 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.gr/products/266643999-fluidmaster-5403-universal-water-saving-long-life-toilet-flapper-3](https://www.desertcart.gr/products/266643999-fluidmaster-5403-universal-water-saving-long-life-toilet-flapper-3) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-18*
