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.
