[Misc] Flush Overflow Help

[CheeseRolls]

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

I am not a plumber, but I've got a similar problem with our downstairs toilet.

Can you find a screw valve on the water intake - in mine, it's a brass pipe at the back of the toilet against the wall.

If so, turn it a quarter turn to the left to stop the water intake. Wait a couple of seconds, and then turn it back to the right a quarter turn. That should solve it until you flush again.

It's just a temporary fix of course. You'll need to fix it permanently with a plumber.

replace the whole thing, they're cheap plastic and don't last long. 5*minute job innit

* probably about half an hour actually.

Sounds like the float valve needs replacing

Agreed.

The make is a (not very) Jollyfill valve, in the bin and fit a Fluidmaster or Dudley Hydroflow.

A new Sistine needed?

A fluid master, that'll get your juices flowing. to a point.
