I have a flush toilet with the centrel push button in the middle where the overflow goes directly into the pan. it is constantly overflowing at a trickle and as i'm use to the ball cock type of toilet I dont know why it's happening or what the solution could be to correct this?
I've recently "fixed" two Roca toilets in my daughter's flat which both continued to trickle after flushing. I found that when the casing holding the buttons was tightened the dribble increased. My conclusion was that the column containing the flushing mechanism was not plumb below the hole in the lid. When the plastic screw was tightened it pulled the column slightly out of line - just enought to break the seal in the flushing mechanism and thus causing the trickle. I slackened off the screw until the trickle stopped. I then put buttons back on. Of course, the casing holding the buttons moved about a little - this was solved by putting a little clear glue under the circular top of the button unit. Once the glue set this was trimmed. The problem was solved without having to buy any new washers, etc. Worth a try.

A washer like diaphragm will need to be replaced to stop the leak
