Toilet keeps filling then overflowing

Hi all,

I recently had a hot water leak in the shower in which I had to shut off the supply and drain from hot press tank to stop the leak.

Since the leak has been fixed and the water has been restored - having issues with the upstairs toilets, two of them - they both appear to continuously fill until it reaches the overflow tube - thus a running toilet. I've adjusted the float lower down to see if that helps - but it keeps filling up. I've manually tried to lift the float up and down to see if the valve shuts but I don't think it is.

Apologies if I have not explained myself properly - I've uploaded a video below - water has reached the float but water still filling from the top of the inlet tube.
