There are many reasons for a leak from a toilet cistern. This article describes one of these step by step, namely, contamination of the seat and valve (petal) of the drain fittings. From the article, you will also learn how to make its safe prevention on your own..
One of the problems with the leakage of the toilet bowl drainage system is that the bowl of the toilet bowl, in which the drain fitting is located, is an open type tank with standing water. As a result, there is an accumulation of rust, lime, salts and even microorganisms. Settling on seal parts and rubbing elements, they disrupt the operation of the drain system and lead to premature wear..
Getting ready for work
To repair the drain fittings, no special tools are required. We need a cotton rag, a container of water (basin, bucket) and a work platform.
Let’s get started
1. We shut off the flow of water into the tank. If there is a separate tap for the toilet, we use it. If not, shut off the common water supply valve.
Advice: if you have to shut off the entire household water supply, stock up on water, because you will need it during the cleaning process.
2. Completely drain the toilet bowl.
3. Unscrew the drain button. To do this, press on its center, pinch the inner and outer sides with your fingers and turn it counterclockwise.
Tip: remember how the button is located relative to the tank lid and count the number of revolutions until completely unscrewed.
4. We take out the button.
5. Remove the cover and put it away from the work site so as not to break.
6. Remember the position of the drain valve relative to the tank.
7. Unscrew the drain fittings by grasping the base and turning it counterclockwise a few degrees.
Tip: Excessive loosening force is unacceptable. If the plastic does not give in – think if you are doing everything right, look at the instructions for your product, because types of drainage systems differ.
8. We remove the reinforcement.
9. We inspect the drain fittings and the inside of the tank.
10. We clean the inner walls of the tank with a rag.
Tip: turn on the water supply to the toilet for this time.
11. Clean the valve seat (where the rubber seal fits). It is necessary to clean it not only from dirt, but also from petrified deposits. For this, mechanical means must not be used so as not to damage the impression. You can try to clean with your fingernail through a rag.
12. We rinse the tank capacity. If the water entering it is not enough for flushing, then it is necessary to pour water into it from a previously prepared container (basin, bucket). We block the flow of water into the tank.
13. Inspect the drain fittings for wear and tear. If the rubber is intact, we continue to work.
14. Remove the rubber seal of the valve by pulling its edge towards you, thereby releasing it from the groove. We remember its position before removal.
15. We clean the rubbing parts of the reinforcement from plaque and the groove in which the rubber seal is located with a rag.
Advice: if the reinforcement does not jam in operation and moves freely, wipe only its outer (visible) elements. By moving the system to the “open-close” position, you can reach almost all nodes.
16. We rinse the system under running water or in a previously prepared container.
17. Put the rubber seal back on, pulling one of its sides into the groove and evenly fill.
18. Install the cleaned drain fittings. Taking the base, we put it in the grooves and turn it clockwise a few degrees until it clicks into place.
19. We clean the tank lid before installation.
20. Installing the cover.
21. We twist the plug to the number of revolutions by which we unscrewed earlier.
22. Set the button to the position in which it was before the system revision. You don’t have to get used to it again.
23. We supply water to the tank. We are waiting for filling. We check the operation of the drain modes and the tightness of the closure. Work completed.
Achieved results: the drain fittings fulfill their purpose, after draining it immediately closes. the settings of the drain modes are not violated.
