I apologize that I don't know the right terms for this.
I have a toilet that in the tank, the little plastic set screw that's opposite the float ball which is used to push down the button when the ball reaches the desired height appears to have somehow stripped. Either the screw or the hole it screws in seems to be stripped because when I try to adjust it, the first time it presses against the button (when it should stop water flow into the tank), it just loosens all the way up and water keeps coming in.
I know the right way to fix it is to replace the whole unit from where the water enters the tank through the float ball. What I'm wondering, because the last time I did that with another toilet it made a big, wet mess, can I just get some locktite and put it on the screw and set it where I want it, let it cure a few days and then go with it without replacing everything? Will that work?
