A toilet leak is one of the leading water wasters, usually leaks tend to go unnoticed for long periods. If you suspect that your toilet is leaking, finding the source of the leak is the first step for you take. In order to determine if your toilet is leaking, look at the toilet bowl after the toilet tank has stopped filling up with water.
How to locate the toilet leak
If the water is still flowing into the bowl, or if you can still hear water running even when the tank has stopped filling up with water then this means that yourtoilet is leaking.
Most toilet leaks occur at the overflow pipe or at the plunger ball inside the toilet tank. To identify the source of the leak, lift off the toilet tank lid and flush. After flushing, the water level should come up to about 1/2 an inch or below the overflow pipe.
To shut off the water level, adjust the float level control screw if need be. If the valve itself is leaking then it needs to be replaced. Sometimes, water may not be seen or heard flowing, this may mean that your toilet has a small silent leak.
If suspect a silent leak, pour in a few drops of coloring into the toilet tank and don’t flush. wait for about 10 minutes. If the colored water appears in the toilet bowl, then this means that your toilet has a silent leak. The silent leak might be located in or around the plunger ball or flapper valve at the bottom of the toilet tank.

Check and see if the leak is on the float ball. If more than half of the float is underwater then it could be leaking. Turn off the water supply by turning the valve in a clockwise direction and flush the toilet to empty it.

The most common causes of toilet leaks are usually a faulty supply line and worn out wax rings. With the right tools and proper knowledge, this is something that you can to do yourself. You will need the following tools to fix the toilet leak.
How to replace the faulty supply line

Use a towel to dry up the water around the toilet, wait for about half an hour to determine the source of the leak.
Step 2: Remove the old supply line
Use the adjustable wrench to disconnect the hex nuts that connect the old supply line to the shut off valve and the toilet tank.
Step 3: Replace the old supply line
Attach the wide, cone shaped end of the plastic replacement supply line into the shutoff valve ans replace the hex nut. Gently slide the brass compression nut over the tube, with the open end of the tube facing the toilet tank, followed by the plastic compression ring tapered side up.

Step 2: Unscrew the hex nuts
Using your wrench, unscrew the hex nuts on both sides that hold the toilet base in place.
Step 3: Remove the old wax ring
After unscrewing the hex nuts, lift the toilet off and turn it over. Use the putty knife to scrape off the old wax ring. Scrape off any residual wax from the flange part as well. You can use some mineral spirit to completely remove the old wax ring. The surface should be extremely clean before attaching the new wax ring
