Causes of toilet leakage - Toilet leakage treatment method
Causes of toilet leakage
Improper design:
causes the various mechanisms of the water tank accessories to interfere during action, resulting in water leakage. For example, when the water tank is discharged, the float ball and the float club fall after falling, affecting the normal reset of the flip plate, causing water leakage. In addition, the floating club is too long and the floating ball is too large, causing friction with the water tank wall, affecting the free rise and fall of the floating ball, resulting in failure of the seal and leaking.
② Excessive pursuit of miniaturization of water tank accessories:
causes the floating ball (or floating barrel) to be insufficient. When the water floods the floating ball (or floating barrel), the water inlet valve cannot be closed, causing water to flow into the water tank continuously, and eventually flow from the overflow pipe into the toilet, causing water leakage. This phenomenon is particularly obvious especially when the tap water pressure is high.
③ Low material:
Some manufacturers blindly reduce production costs and use inferior materials to cause the water outlet and water inlet pipe to crack during injection molding, resulting in failure of sealing. The water in the water tank flows into the toilet through the drain valve overflow pipe, causing "long-term flow of water",
④ The pressure differential water inlet valve has not been added with a filter:
Impurities in the water are very likely to block the small holes of the seal ring, causing the water inlet valve to be unable to close and the sealing failure.
⑤ The drain valve sealing bonnet and the valve body sealing surface are not tightly matched:
causes water leakage. There are two major categories of sealing valve cover and valve body sealing surface: wired contact sealing and surface contact (flat or curved surface) sealing. Most of the traditional flip-type sealing valve covers are wire contact seals. From the inspection, the material of the flip plate is improperly selected; the flip plate itself is deformed or is compressed in water; the flip plate is misaligned after use; the process defects of the valve body sealing surface are the main reasons for water leakage in the drain valve itself. The drain valve with surface contact sealing has better sealing properties than the drain valve with line contact sealing.
⑥ The connections of the drain valve are not tightly sealed:
The non-disposable drain valve is not tightly sealed at the coupling. Under the action of water pressure, water flows into the toilet through the interface gap through the overflow pipe, causing water leakage. A lifting and lowering water inlet valve that can freely change its height. If its sealing ring is not closely matched with the pipe wall, water leakage will often occur.
Water leakage treatment method
When you turn the handle on the water tank to flush the toilet, the starting rod in the water tank will lift. This bar will pull the steel rope upwards, and then pull up the ball plug or rubber cover at the bottom of the tank. If the opening of the flush valve is unobstructed, the water in the tank will flow through the raised ball plug and rush into the barrel below. In this way, the water level of the barrel will be higher than the water level in the bend.
When water pours out from the water tank, the float ball floating on the water surface of the water tank will drop, pulling the floating arm downward, thereby raising the valve plunger of the float valve device and allowing the water to flow into the water tank again. The water always flows to the lower level, so the water in the tank pushes the water in the barrel, which flows into the drainage pipe, thus creating a siphon effect, taking away everything in the barrel. When all the water in the barrel flows away, the air is sucked into the bent tube and the siphon stops. At the same time, the water tank ball plug will fall back to its original position, closing the opening of the flush valve.
The float will rise as the water level in the water tank rises until the height of the floating arm is sufficient to press the valve plunger into the float valve and close the incoming water flow. If the water cannot be turned off, the excess water will flow down the overflow pipe into the barrel to prevent the water from overflowing in the tank. If water continues to flow from the water tank into the tank and into the drain pipe, the processing steps are as follows:
Step 1: Lift the floating arm upward. If the water stops flowing, the problem is that the float cannot be lifted to a sufficient height to press the valve plunger into the float valve. One of the reasons may be that the float rubs against the side walls of the tank. If this is the case, bend the floating arm slightly so that the float leaves the side walls of the tank.
Step 2: If the float does not touch the water tank, grab the float arm and do not let go, then turn the float counterclockwise and remove it from the end of the float arm. Then shake the float to see if there is any water inflow, because the weight of the water will prevent the float from rising normally. If water is infiltrated into the float, please throw the water out and then reinstall the float on the float arm. If the float is damaged or corroded, replace it with a new one. If there is no water in the float, put the float back in place and gently bend the float to lower it low enough so that the float stops fresh water from entering the tank.
Step 3: If none of the above steps can solve the problem, please check the water tank ball plug at the flush valve seat. Chemical residues in the water may cause the plug to be unable to move to the right position, or the plug itself has decayed. Water will seep from the opening of the flush valve into the barrel below. Close the water closing valve of the toilet, then flush the water tank and drain the water tank. You can now check the tank ball plug for signs of wear and install a new ball plug if necessary. If the problem is caused by chemical residues accumulated at the flush valve opening, use some emery cloth, wire brush or even a knife that is dipped in water or not to dip in water to remove the residue.
Step 4: If there is still excessive water flowing through the toilet, it may be that the guide or lifting steel rope of the lift tank ball plug is not aligned or has been bent. Make sure the guide is in the correct position and the steel rope is directly above the flush valve opening. Rotate the guide until the tank ball plug falls vertically into the opening. If the lifting wire is bent, try to bend it back to the right position, or replace it with a new one. Please make sure that the starting rod does not cause friction with any part and that the lifting cable is not penetrated into the wrong hole in the rod. Both of these situations will cause the water tank ball plug to fall at a certain angle and cannot plug the opening.
