On most toilets, there are two large bolts holding the tank to the bowl. In time, these bolts may start to leak because the rubber washer on the inside and outside of the tank have started to wear out from all the flushing. You can tell you need new washers because there will be drops of water on the bolts, nuts, and the floor. If rusted, the washers, nuts, and bolts should all be replaced. By following these steps, you should be able to complete the task by yourself.
Step One: Drain the Toilet Tank
First, you need to turn off the water shutoff valve to stop water from coming into the toilet. Then, you can flush the toilet until it is completely empty. Use an adjustable wrench to pull the water supply line away from the toilet tank. You should have sponges and towels handy to absorb any overflow water.
Step Two: Secure the Tank Lid
Carefully remove the toilet tank's lid and set it aside. Ideally, you want to put some blankets and/or towels underneath and on top of the lid. This will protect it from accidentally getting broken.
Step Three: Remove the Tank Bolts
Use the wrench to take the nuts and bolts off the tank. If they are stuck, you may need to hold the nut in place with the wrench while someone else uses a screwdriver to undo the bolt from the inside of the toilet tank. Once the bolts are removed, lift the tank straight up and gently sit it down on the towel and blanket padding you have already set up for the lid.
Step Four: Replace the Washers
Finally, you can extract the bolts from the toilet tank and remove all of the worn out washers. Throw the old washers away and replace them with new washers. One rubber washer should be placed directly under the head of the bolt. Insert the bolt into the bolt hole in the toilet tank. Place another rubber washer on the bolt that is on the outside of the tank and then attach the bolt nut to the bolt. Add a rubber washer to the outside of the nut followed by a metal washer to secure the toilet bowl housing in place. Finally, you can repeat these steps to get the second bolt in place.
Once you've completed these four steps, you can put the tank and tank lid back on your toilet. Finally, you can refill the toilet with water and start using it again. Just remember to check the washers, nuts, and bolts for a few days to make sure the leak is gone.
