Identify the leakage source

The first step should be identifying where the leakage is coming from. You can perform the following tests.

1. Testing the tank

If you hear some sounds from the bowl, chances are that there might be a problem with the tank. You can add some food color in the water in the tank and then allow your toilet to remain for 30 minutes without being used. Tinting of your bowl water will be a clear sign that the leakage id from the tank.

You should check some tankless toilets in case you don’t want a toilet with tank.

2. Testing for the toilet bowl leakages

Add some food color into the water in your toilet tank and allow it to settle for thirty minutes. Use a paper towel to wipe around the external part of the bowl. Remember to wipe the floor around the toilet immediately. If you see some tinted spots on the paper towel, then it means that the leakage is from the toilet bowl.

3. Handle

The most common cause of toilet leakages is caused by the handle assembly. Try to jiggle the handle and if you will no longer hear the leakage sound, there might be a problem with the assembly. Handle leakages are very easy to fix since in most cases they normally involve a bad flapper or a loose chain.
