Hi
I fitted a Siamp Optima 50 flush valve a long time ago then in 2014 I replaced all the parts because it wouldn't stop filling after a flush. Now it's doing it again.
The overflow pipe lifts up when it's flushed but it won't drop down again of its own accord, so the cistern never fills.
I don't know why this should happen, except perhaps it is just an accumulation of grime.
Should I accept this as a normal life span and fit a replacement unit or is there an easy fix?
