It usually happens when the flapper isn’t tight enough or damaged.

How to fix a Toilet Leak by Yourself

Fix Flush Valve Leaks

Start by removing the tank lid and flushing water. When you flush the toilet, the tank ball drops and refills. Then, add several drops of dark food coloring. You must wait for at least 20 minutes, and if you see a slight trace of color in the toilet bowl, there is a leak.

Replace a Float Cup Fill Valve

For the second step, adjust the height by twisting the shank in and out of the valve body. Then, place the valve in the tank, turn on the water, and adjust the water level.

Replacing a Float Ball Fill Valve

Check the height of the valve and adjust if there is a need. Now, position the valve in the tank inlet hole. Just make sure that the placement of the rod arm is not hindering the movement of the float ball. It’s time to screw the rod arm into the valve arm and the float ball into the rod arm. At the end of the process, turn on the water supply.

Replace a Flapper

Now you come to the part where you need to replace a flapper. Begin by sliding the lower lift wire through the upper lift wire and then through the guide arm on the overflow pipe. You need to fasten the lower lift wire to the tank ball, aligning the tank ball over the drain seat while keeping the wire vertical. Don’t forget to check if the ball sits properly or not.

Replace a Flush Valve

In this process, you need to cut the overflow pipe to match the height of the old pipe. Next, install the valve and secure the lock nut as tightly as you can. Then, onto the end of the valve, carefully slide the gasket. Next, connect the flapper chain to the toilet’s flush lever and fasten the refill tube to the pipe. For the last step, reconnect the tank to the bowl. Lastly, wash the work area with a disinfectant for a cleaner and hygienic toilet.

Final Word

If you follow these steps, you will be able to fix the common toilet leaks more efficiently and like a pro. In case you feel the need to call a professional, don’t hesitate to do so. You never know what you will learn from their professionalism and work experience.
