Hi team.
I have Corona Stylus toilet and after many years of non-problematic use I have noticed that its starting to make constant hissing sounds even when the cistern is full. From what I can tell this sound seems to be from micro jets of water coming out of what I presume is the inlet valve (please see attached image). Can someone please recommend the ideal fix? Should I replace the entire inlet valve?
Thanks

Welcome to the Bunnings Workshop community @BobN. It's great to have you join us, and many thanks for your question about repairing a toilet.
It sounds like the constant hissing sound is likely coming from the inlet valve, which could be due to a worn or damaged washer. You can either replace the washer in the inlet valve or, if you suspect the valve may be faulty, it's often a good idea to replace the entire valve. A reliable option would be to replace it with a Fluidmaster Bottom Entry Toilet Inlet Valve, which is known for being durable and effective. This could help resolve the issue and prevent any further problems with your toilet's flushing mechanism.

Please let me know if you have any questions.
