When you flip the handle on the tank to flush the toilet, the tank will be lifted up within the starter.
If the opening of the flush valve is unobstructed, the water in the water tank will flow through the ball plug which has been raised, and rushes to the bottom of the bucket.
So that the water level of the tub will be higher than the water level in the elbow.
When the water from the tank in the gushing, floating in the water tank float will fall, pulling the float arm down, thereby raising the float valve valve device plunger, so that water flows into the water tank.
The water is always flowing downwards, so the water in the tank propels the water in the tank, which flows into the drain pipe, producing a siphon effect, which takes away all the contents of the tank.
When all the water in the tub is gone, the air is sucked into the elbow and the siphoning stops.
At the same time, the water tank ball will fall back into place, close the flushing valve opening.
The float will rise as the water level in the tank rises, until the height of the float is sufficient to press the valve plunger into the float valve and close the incoming water flow. Fig.
If you can not turn off the water, the excess water will flow down the overflow pipe into the tank, so as not to overflow the water tank.
If water continues to flow from the tank into the tub and into the drain, the processing steps are as follows: Step 1: Lift the float arm upwards, and lift the float arm upwards, as shown in the following figure.
If the water ceases to flow, the problem is that the float can not be raised to a sufficient height to press the valve plunger into the float valve.
One of the reasons may be that the float creates friction with the side walls of the tank. If this is the case, bend the float arm slightly so that the float leaves the side of the tank.
Step 2: If the float does not touch the tank, grasp the float arm and do not let go, then turn the float counterclockwise to remove it from the end of the float arm (see Fig. 2).
And then shake the float to see if there is no water, because the weight of the water will not float properly, if the float into the water, please throw out the water, and then re-install the floating ball float arm.
If the float is damaged or corroded, replace it with a new one.
If there is no water in the float, replace the float in place, and then gently bend the float rod to a low enough position so that the float prevents fresh water from entering the tank.
Step 3: If none of the above steps can solve the problem, check the water tank ball plug at the flush valve seat.
Chemical residues in the water may cause the ball plug to move to the proper position, or the ball plug itself has been decayed.
Water will seep into the lower tank from the opening of the flush valve.
Close the flush valve of the toilet and flush the tank.
You can now check the water tank ball plug for signs of wear, if necessary, you can install a new ball plug.
If the problem is caused by chemical deposits on the flush valve opening, remove these residues with some dipped in water or dipped in water with emery cloth, wire brushes or even a knife.
Step 4: If there is still excess water flowing through the toilet, it may be that the guide or lifting wire of the lift tank ball plug is not aligned or has been bent.
Make sure that the guide is in the correct position and that the rope is just above the flushing valve opening.
Rotate the guide until the water tank ball plunger falls vertically into the opening.
If the hoisting rope is bent, try bending it back to the correct position or replacing it with a new one.
Make sure that the lever does not rub against any part and that the lifting cable is not worn in the wrong hole in the rod, both of which can cause the tank ball plug to fall at an angle and fail to plug the opening.
