Toilet cistern overflowing...

[hippygirl]

Hi all...I would like some advice, before I call a plumber in, in case this problem is something I can fix myself.
View media item 10299 View media item 10298 View media item 10297There is a slow trickle of water coming out of the water inlet, through slits just underneath the arm, which is causing water to constantly flow into the toilet. After flushing the cistern fills to above the line and starts to flow into the pan. Is there anything I can do?
Many thanks for reading....

sounds like you may need a new diaphragm or you could try stripping it down give it a clean etc.
