Give it a slight turn to stop it from rubbing on the side

You all most have to adjust the height before its installed,then you just hold the bottom and turn the top.

The first thing I would check is to make sure that the body of the float or the linkage that connects the float to the top of valve are not rubbing on inside of the tank and stopping it from moving freely.
Also when tank is full hold float down so that all air that is inside the top of the float is let out. I hope this hepls you. Thanks.

universal flappers fit all different ways you may have to cut or alter the tabs or o-ring to make it sit right also check chain is set right

Your flapper has a slow leak. Replace it.

Although it looks like the leak is coming from the hose side, it might still be coming from the swivel nut. Snug it up no more than 1/8th of a turn. If leak persists, snug it again. If still leaking, replace the supply flex.

First shut water off at stop than flush all the water out of the tank next take a sponge and get all the water out of tank next unsrew the supply line from the valve under tank than move out of the way next unsrew the nut on the valve of fluidmaster than pull the fluidmaster out of tank stick the new fluidmaster in tighten nut srew the supply line back on turn on stop and let the tank fill up thats it if the fluidmaster dont shut off press the handle let some water out and adjust the fluidmaster screw Tip the water should stop a 1/4 inch below the flush valve tube in center of toilet

You move the float that rises up when the bowl fills down. You will need to play with the adjustment to see what level you want.

mary you have to give some idea of what you are trying to fix repost the question stating exactly the make , model, year or type of equipment that you are fixing where it is used and what it is used for

Change your fill valve. It is probably clogged after time they get a calcium build up

If the tank is not filling you probably have to replace the fuild master in the tank. They get clogged up with dirt or hard water calcium build ups.

It sounds like it is broken you would have to replace it.

What's wrong with that that's were it should be.with a 2.5 gal tank that water level is corect.Iff think that's too much, adjust the water level adjust clip, by sueezing clip and move it down to adjust the water levelto lower.

There should be a adjustment screw at the top of the fill valve, screw it up or down to adjust the tank level.

Why is the water leaking out of the tank? There's only reason for that, the water is slowly leaking by the plunger.check the plunger aT The bottom of the tank it's activated by the handle.shut the water supply off empty the tank,clean the bottom of the plunger refill tank .problem should be fixed if not replace plunger.. Happy plumbing.
