hi i am dan, it sounds like you may have multiple issues but we will take them one at a time. first if the toilet is constantly running then that means it is loosing water somewhere and the float is probably just doing its job. most of the time it is the flapper that is leaking by so i would recommend to just replace the flapper since that will be the cheapest and easiest to replace and see if the water running stops then.
did this help you or is it still not working properly?
i would first start with the flapper leaking by if it is leaking even holding it down will not stop it. i would replace just the flapper and make sure it is adjusted properly then the water should stop running once full. it is recommended to replace flappers every 6 to 12 months as they are cheap and easy to replace and wear out fairly easily. if replacing that doesn't work let me know
Ok. Let me know
