(Hope next one works) *by C***K on Reviewed in the United Kingdom on 26 January 2021* Shutting off the flow from the intake stopes the water overflowing into the bowl. Flushing the cistern then turning on the flow again you can watch the water rise in the cistern raising the float. (Lifting the float should stop the inflow. It doesn’t). The rising water continues till the float stopes but the water keeps rising till it flows into the overflow tube emptying continually into the bowl. That’s the same problem as this was bought to fix. Two Fluid-masters still the same problem. NEW INTAKE VALVE WORKS FINE. CAN ONLY THINK FIRST WAS A REJECT PUT BACK IN STOCK AND SOLD AGAIN ### ⭐⭐⭐⭐ Easy to fit *by J***M on Reviewed in the United Kingdom on 23 February 2021* It was rather easy to install this new part for the toilet. no leaking as expected. the only difficult part is the plastic screw part that goes against the underside of the cistern because it has to be tight, but otherwise anyone can do this. ### ⭐⭐⭐⭐⭐ Exactley what I needed 'THank You' fast delivery esy instruction. *by C***Y on Reviewed in the United Kingdom on 15 October 2021* Simple Instructions & Easy to fit 'Thank You Amazon' --- ## 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.pl/products/92486879-fluidmaster-400uk-1-2-bottom-entry-inlet-float-valve-uk](https://www.desertcart.pl/products/92486879-fluidmaster-400uk-1-2-bottom-entry-inlet-float-valve-uk) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-27*
