Overflowing toilets require quick thinking plus quick action, however it’s not hard to take care of it if you guess how! Remove the lid from the toilet tank quickly plus carefully plus set it aside; Place it somewhere secure, but don’t worry about sitting it on towels or anything prefer that; Remember, you don’t have much time to lose! 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 water, the flapper is the rubber piece in the center of the tank’s bottom… 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 have secured the flapper valve, however 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 separate from worrying about it overflowing; Keep an eye on it so you can stop it if the level increases.
If the water level doesn’t start 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… Close it by turning it clockwise. If you can’t reach the valve while holding the float, let go of the ball plus close the valve as fast as you can, but stop using all plumbing fixtures as soon as the toilet stops overflowing plus use a plunger to see if you can clear the blockage. If only 1 toilet is clogged, the problem is most likely just with that toilet, however, if more than 1 toilet is affected, you may have a clogged program drain or a failing septic system.
