I saw one person complain that a problem with the float valve caused a leak and damage; this kit does not include the float valve, so I do not know what that person was talking about. Another person complained about there only being two bolts; yes, that is how many you need. The entire process took me 1.5 hours, including cleaning and having to remove the old, corroded parts. One place in the instructions did not make sense, as it seemed to indicate putting a nut on over a bolt before that bolt goes through a hole. The diagram was more clear. They should also mention that the tank will be wobbly sitting on the gasket to the bowl portion before the nuts to either side get their final crankdown. Sure hope that it lasts, but I am purchasing one for an idential toilet. ## Frequently Bought Together - Fluidmaster 507AKP7 PerforMAX Universal High Performance 2-Inch Toilet Flush Valve Repair Kit with Gasket and Bolts - Fluidmaster 400H-5003 Performax Universal Toilet Fill Valve with Tank and Bowl Water Control 2-Pack, Blue - Fluidmaster 502P21 PerforMAX Universal Water-Saving Long Life Toilet Flapper for 2-Inch Flush Valves, Adjustable Solid Frame Design, Easy Install, Red, 1 pack --- ## 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.sg/products/266644005-fluidmaster-507ak-performax-universal-high-performance-2-inch-toilet-flush](https://www.desertcart.sg/products/266644005-fluidmaster-507ak-performax-universal-high-performance-2-inch-toilet-flush) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-07-07*
