Lately, our 4+ year old Toto Drake has been making a strange rhythmic sh-sh-sh-sh sound, reminiscent of a rotating sprinkler. This occurs many minutes after a flush has occurred and (seemingly) finished. Usually it's a pretty quiet sound, but sometimes it switches to a very loud version of the same sound, which lasts for a few seconds and then all noises cease. The noise definitely appears to be coming from the fill valve.
Any ideas?
If it matters, for quite some time the toilet has seemed to have a leak somewhere: If you pour a cup of water into the full bowl, it sounds like a cup of water is slowly leaking out. Apparently into the drain pipe, since there is no sign it's going onto the floor or otherwise outside the pipes.
