From time to time our toilet makes a sound as if there is water going into the cistern, but only very briefly: it only lasts only a second or so, if that. There seems to be no obvious reason for it happening (it doesn’t seem to happen when we run taps, or when we have just flushed it etc). I’d say we hear it maybe every couple of days but of course it might happen more often than that and we just don’t notice. It doesn’t sound like water going into the pan though I haven’t seen into the pan when it happens. It's probably been happening for a couple of weeks.
So, thinking it might be the fill valve I did a like for like replacement but heard the short ‘extra’ sound again last night. Does anyone have any suggestions as to what it might be and/or how to fix it (e.g. replacing the flush valve?) There’s no sign of a leak into the pan.
I’ve put a picture of the set-up below. The fill valve is new, the flush valve probably 5 or so years old. Except for the sound of ‘extra’ water, the whole thing works fine.
Thanks,
