Details
A leaking flush valve often causes a constant trickle of water into the toilet pan, and this leads to significantly higher water bills and annoying background noise. Additionally, standard “universal” washers often fail to create a proper seal because they do not match the exact specifications of the PRO550 or PRO750 valves. This Fluidmaster Replacement Diaphragm solves these frustrations because the precision 63mm x 32mm dimensions provide an airtight, factory-standard fit. Moreover, the high-grade rubber material stays flexible even in hard water areas to prevent future warping. Therefore, you restore your toilet to perfect working order while you avoid the expense of a full valve replacement.

Fluidmaster Universal Toilet Flush Flapper Replacement | Water Saving Adjustable Valve Seal Spare
In stock
Genuine Fluidmaster replacement flush flapper designed to stop water trickling into the toilet bowl. This high-quality seal is the standard fix for toilets that won't hold water in the cistern. Pro Tip: Unlike the "hiss" of a faulty fill valve, a worn flapper is usually a silent culprit. If you see a constant ripple of water at the back of the toilet bowl, or if your cistern "ghost flushes" (refills itself every hour without being used), this perished rubber seal is your most likely fix.
