FAQ

Why is my toilet leaking around the tank?

To fix a toilet gasket issue, start by removing the two bolts that connect the toilet tank to the toilet bowl. This can be done using a screwdriver and an adjustable wrench. These bolts are equipped with rubber gaskets or washers that prevent leaks. Replace these worn-out gaskets with new ones to ensure a proper seal and prevent any future leaks.

Should there be space between toilet tank and bowl?

To ensure a proper seal and prevent leaks, it is important to tighten the tank bolts of a toilet correctly. Most toilets have a small gap, typically ranging from a ¼ to a ½ inch, between the tank and the bowl. If the bolts are too loose, water can seep through the rubber washers and down the bolts, causing leaks. On the other hand, tightening the bolts too much can lead to the tank cracking. Finding the right balance in tightening the tank bolts is crucial for maintaining a leak-free and functional toilet.

Why is my toilet leaking at the bottom of the tank when I flush?

To prevent leaks from the base of your toilet when you flush, make sure to tighten the toilet tee bolts. These bolts secure the toilet to the floor and if they are not tightened properly, the wax ring underneath them may not create a water-tight seal. To fix this issue, begin by removing the caps using a putty knife or flathead screwdriver, and then tighten the bolts securely. By doing so, you can ensure that your toilet remains free from leaks and operates smoothly.
