Dudley japtic syphon. The first flush works fine, the cistern fills up fully straight afterwards, but when you try to flush again it doesn't flush. You can try a few more times and it still won't flush. Leave it 3-4 minutes and it flushes fine again.
Should I just replace the syphon or washer part or is there something else that is so obvious that I could do to make it flush again once the cistern is full after the first flush?
