Hi
Suggestions please (including all the usual nonsense as goes with the territory)
The upstairs toilet cistern keeps on filling and then constantly overflowing through the round pipe at the top of the image. This is just adding to my water bill, not doing any damage
I have tried adjusting the red screw at the bottom of the image. Crucially even if I pull this right up by hand the water is still filling. If I push it down the water fills much faster (as expected)
It looks to me like I new to replace the float and valve mechanism at the bottom of the picture. Is there anything I have missed, or should try, before calling out a plumber?
Thanks
