Understanding the Toilet Flange

Before we jump into the process of fixing a toilet flange, it is essential to understand what exactly a flange is and its role in the functioning of a toilet.

The toilet flange, also known as a closet flange or closet bend, is the pipe fitting that connects the toilet bowl to the sewage pipe. It is typically made of PVC or cast iron and is secured to the floor using screws or bolts.

The flange has two primary functions. First, it acts as a secure base for the toilet bowl, keeping it firmly in place. Second, it provides a watertight seal to prevent leaks and odors from escaping into the bathroom.

The flange has a circular opening that matches the shape of the toilet bowl’s base. This allows the toilet to sit flush against the flange, creating a tight connection. The flange also extends above the floor level to accommodate the wax ring, a crucial component that forms a watertight seal between the toilet and the sewage pipe.

Understanding the anatomy of a toilet flange is important for diagnosing issues and making the necessary repairs. Now that we have a basic understanding of the toilet flange, let’s move on to learning about the signs of a damaged flange.
