Next, press down on the flapper valve inside the toilet tank; You don’t need to worry about the sanitary conditions of the tank’s waterâ€¦ The flapper is the rubber piece in the center of the tank’s bottom, but by doing this, you should be able to prevent more water from entering the bowl plus from overflowing, lift up on the float that operates the tank fill valve once you’ve secured the flapper valveâ€¦ As the main water supply is shut off, the water level in the bowl should slowly decrease. After about a minute, when the water level returns to normal, you can let go of the float plus let the bowl refill without worrying about it overflowingâ€¦ Keep an eye on it so you can stop it if the level increases. If the water level doesn’t beginning to drop after about a minute, continue to hold the float while you shut off the water at the toilet supply valve, situated near the floor or in the wall behind the toilet, and close it by turning it clockwise.
