Causes of water tank leaks: internal and external
Every time you hear the sound of water running continuously from your water tank, it could mean that there is a leak.
First, it’s important to understand that the causes of water tank leaks can be broadly categorized into two groups: internal and external. Internal leaks are usually due to deteriorated or damaged parts, such as flapper valves, fill valves, etc., while external leaks usually involve sealed parts of the tank, such as bolts or gaskets.
Common signs of a leaking toilet tank
- The water inside the tank keeps flowing into the toilet
- Water dripping or pooling on the outside of the tank
- Hearing a constant flow of water, even when not flushed
Tools and materials needed
- Wrench: for tightening or removing bolts.
- Screwdriver: to help you adjust or remove some of the small parts.
- Replacement valve flap: when the original valve flap is worn or damaged.
- Tank-to-tank gasket: acts as a seal between the tank and the toilet.
Now, grab your tools, and let’s see how to fix this problem solution step by step.
Steps to fix an internal leak
1. Check the flapper valve
This is a crucial part as the flapper valve functions to control when the water in the tank enters the toilet.
2. How to check if the flapper is damaged?
First, open the tank lid and look at the flapper. If it looks worn or no longer fits tightly on the bottom of the tank, then it’s probably the problem.
3. To replace a worn flap.
Turn off the water inlet valve and empty or drain the tank. Then, remove the damaged flap and install a new one following the instructions in the manual or on the package.
4. Checking the water fill valve.
The water fill valve controls the level of water in the tank, and if it is faulty, it may cause the tank to continually fill with water, which can lead to internal leaks.
To adjust the water level. Look at the water level mark in the tank and make sure it lines up with the mark on the water fill valve. If it does not line up, you can use a screwdriver to adjust it.
5. Replace the faulty water fill valve.
If the problem persists after adjustment, then the water fill valve may have been damaged. In this case, you will need to purchase a new one and follow the instructions for replacement.
Dealing with external leaks
1. Tighten the tank bolts.
Tank bolts are the parts that connect the toilet to the tank, and if they become loose, they can cause leaks.
Proper technique to ensure even pressure. When you tighten the bolts, make sure the pressure is even on both sides to prevent the tank from cracking or warping. If the slow water fill is due to a cracked tank, you can check out ways to fix a cracked tank.
2. Replace the tank-to-tank gasket.
This is another critical part of the connection between the toilet and the tank, and if the gasket is deteriorated or damaged, it can lead to leaks.
3. Steps for removing the tank and replacing the gasket.
First, use a wrench to remove the tank bolts. Then, carefully remove the tank, replace the gasket with a new one, and reinstall the tank.
At this point, we’ve dealt with all the common leaks. But there is one important thing to do before we finish.
Test the repair results
After completing all the steps, you need to test the repair. Open the water inlet valve and let the tank fill up with water. Wait a few minutes and check for any signs of leaks. If everything is fine, congratulations, the problem has been fixed!
