Toilet tanks might have a chip or a crack right above or below the water level. For example, the cracks can also be either from the inside or from the outside. The plumbers recommend checking for the actual positioning of the crack to determine what type of servicing will be applicable. 

A crack that is above water level is not a problem if it isn’t that big. If you spot any sort of cracks, above the water level, within your toilet tank, then it is better to mark and observe them for the time being. In case the crack is worsening, then you need to seek repair for the same!

1.     Fixing Porcelain Toilets With Waterproof Epoxy

First, you need to use the right observation power to locate the porcelain toilet tank or bowl cracks. 

Once you have located that, you need to shut off the water supply. 

Flush the tank, empty it, and put pressure on the flush handle to eradicate all water from the tank. Now, remove the lid of your toilet tank. 

Irrespective of the location of the crack, you have to clean it thoroughly with the use of a bathroom cleaner or any lint-free cloth. 

Now, you have to drill through the porcelain with the help of a diamond rotary grinder bit attached to the rotary tool. And drilling should be at the end spot of the crack. Drill entirely through the surface of the porcelain. The hole relieves the pressure upon that crack to ensure that it doesn’t get larger. 

Now, you have to widen the crack to give enough space for the epoxy to settle in. 

Prepare the epoxy solution or paste, and fill the cracks with it. 

Let it dry, and then sand off the excess epoxy coating with the use of 40-grit sandpaper. 

After that, you can apply the finishing to the epoxy!

2.   Fixing The Porcelain Toilet With Polyurethane Glue

It is an additional pick for building a strong bond between the broken bases of your porcelain toilet.
