Details

Cistern maintenance is often plagued by noisy, clunky fill valves that struggle to fit in modern, slimline concealed tanks. Firstly, standard valves are often too bulky, forcing you to compromise on positioning. Worse yet, using cheap plastic threads frequently leads to cross-threading during installation, which can cause frustrating, slow-drip leaks behind your bathroom tiles. Consequently, many homeowners avoid upgrading their inlet valve until a total failure occurs, leading to wasted water and annoying, constant filling sounds. Furthermore, finding a compact valve that handles both side and back entry is a surprisingly difficult task.

Fortunately, this Wirquin Jollyflush inlet valve provides a professional-grade, high-performance solution that saves you significant installation stress. Because it features a solid brass tail, you get a secure, worry-free connection that is built to last. By utilizing the unique swivelling float, you can easily navigate even the tightest cistern geometries, ensuring a perfect fit every time. Ultimately, it is the smartest, most reliable way to restore quiet, efficient flushing performance to your bathroom.
