A cracked toilet tank can be a nightmare for any homeowner. It can cause water leakage, increase your water bill, and even lead to structural damage in your home. However, fixing a cracked toilet tank doesn’t always have to be expensive or time-consuming. In this article, we’ll provide you with a step-by-step guide on how to fix a cracked toilet tank, so you can save time and money.

How to Fix a Cracked Toilet Tank

Diagnose the Problem

Before fixing a cracked toilet tank, you need to make sure that the crack is the only problem. Sometimes, a leaky or running toilet can be mistaken for a crack. To diagnose the problem, add a few drops of food coloring to the toilet tank. Wait for a few minutes and see if the color appears in the bowl. If it does, the problem is most likely a leak or a running toilet, not a crack.

Turn Off the Water

Once you’ve confirmed that the problem is a cracked toilet tank, turn off the water supply to the toilet. You can do this by turning the valve on the wall behind the toilet clockwise.

Drain the Tank

Flush the toilet to drain the water from the tank. Use a sponge or towel to remove any remaining water from the tank and the bowl.

Remove the Tank

Use a wrench or pliers to loosen and remove the bolts that hold the tank to the bowl. Carefully lift the tank off the bowl and place it on a flat surface.

Clean the Crack

Use a sandpaper or emery cloth to clean the edges of the crack. Make sure to remove any debris or dirt from the surface.

Apply Epoxy

Apply an epoxy or plumber’s putty to the crack. Make sure to follow the manufacturer’s instructions and apply enough epoxy to cover the entire crack. Use a putty knife or a small brush to spread the epoxy evenly.

Let the Epoxy Dry

Let the epoxy dry completely before reattaching the tank to the bowl. The drying time can vary depending on the type of epoxy you use, so make sure to check the instructions.

Reattach the Tank

Carefully place the tank back onto the bowl and reattach the bolts that hold it in place. Tighten the bolts evenly, but be careful not to over-tighten them, as this can cause the tank to crack again.

Turn On the Water

Once you’ve reattached the tank, turn the water supply back on and wait for the tank to fill up. Check for any leaks or drips around the tank and the bowl.

Test the Toilet

Flush the toilet a few times to make sure that everything is working properly. If you notice any leaks or cracks, turn off the water supply and repeat the steps above.

It is always recommended to consult a professional plumber for an accurate estimate of the cost.
