How to know if the toilet tank is leaking

1. There is an obvious dripping sound inside to determine that the toilet is leaking.

2. More insidious water leakage can be checked by the following method: red ink is dripped into the toilet tank, after mixing, see if there is red water flowing out of the toilet outlet, if there is any leakage, otherwise it means no leakage.

Reasons for water leakage from toilet tank

â‘  Inferior material: Some manufacturers blindly reduce production costs. The use of inferior materials causes the inlet valve, the drain valve and the inlet pipe to crack during injection molding, resulting in sealing failure. The water in the water tank flows into the toilet through the overflow valve of the drain valve, causing a long running water'.

â‘¡ Excessive pursuit of miniaturization of toilet tank accessories, resulting in insufficient buoyancy of the float (or float), when the water floats the float (or float), the inlet valve cannot be closed, and the water flows into the tank continuously. Water leaking from the overflow pipe into the toilet. This phenomenon is particularly noticeable when the tap water pressure is high.

â‘¢ Improper design: The mechanism of toilet tank accessories will interfere with each other during operation, resulting in water leakage. For example, when the water tank releases water, the floating ball and the floating ball rod will affect the normal reset of the flap and cause water leakage. In addition, the float rod is too long and the float is too large, causing friction with the wall of the water tank, affecting the free lift of the float, and causing the seal to fail and leak water.

â‘£ The differential pressure inlet valve is not equipped with a filter, and impurities in the water are very easy to block the small hole of the sealing ring of the toilet tank, so that the inlet valve cannot be closed and the seal fails.

⑤ The sealing of the bonnet of the drain valve and the sealing surface of the valve body are not tight, causing water leakage. There are two types of seals: the linear contact seal and the surface contact (flat or curved surface) seal between the valve cover and the sealing surface of the valve body. The traditional flap-type sealing valve covers are mostly line contact seals. Improper selection of flap material; deformation of the flap itself or deformation under pressure in the water; misalignment of the flap after use; defects in the sealing surface of the valve body, etc. are the main causes of leakage of the drain valve itself.

â‘¥ The connection of the drain valve is not tightly sealed. The non-disposable formed drain valve is not tightly sealed at the joint, and under the effect of water pressure, water flows into the toilet from the interface gap through the overflow pipe, causing water leakage.

Solution for water leakage from toilet tank

â‘  The material of the toilet tank should be in accordance with the relevant material requirements in the standard of JC707-1997 "Toilet Low Water Tank Fittings", that is, the plastic materials should meet the requirements of GB12670, GB12671 and GB12672 respectively.

â‘¡ The buoyancy of the floating ball (or floating bucket) should be calculated theoretically. At least under the pressure of 0.6Mpa, the sealing of the floating ball can only be guaranteed when it is submerged for 3/4.

â‘¢ Due to the different sizes of toilet water tanks, when designing the water tank accessories, it is necessary to give full consideration to the free movement of each mechanism after installation, so as not to interfere with each other.

â‘£ Add a filter to the inlet valve.

⑤ The material of the valve cover of the drain valve should be selected properly, the production should be fine, and the protection during the packaging and transportation should be strengthened to avoid deformation.

â‘¥ The valve body of the drain valve can be formed at one time, and the structure that can not be formed at one time is preferably assembled with threads and water-resistant adhesives; the lift inlet valve must have at least double sealing rings to ensure its sealing performance.
