Why Should You Consider a Wax Ring Flange for Your Toilet?
You should consider a wax ring flange for your toilet because it creates a watertight seal between the toilet and the floor. This seal prevents leaks and maintains a secure installation. A proper installation ensures that your toilet functions efficiently and reduces the risk of water damage.
According to the American Society of Plumbing Engineers (ASPE), a wax ring flange is defined as a sealing component utilized during toilet installation to connect the toilet base to the drainage pipe. The primary purpose of this component is to create a barrier that prevents wastewater and odor from escaping into the surrounding area.
The need for a wax ring flange arises from the requirement for a reliable and durable seal. When a toilet is installed, it sits above the drain and must connect securely to avoid leaks. The shape and material of the wax ring allow it to conform to any irregularities in the toilet base and the flange on the floor, providing a complete seal. This prevents any potential leakage, which can lead to water damage or unpleasant odors in the bathroom.
A wax ring is essentially made of soft wax, which provides flexibility and can adapt to slight variations in surface texture. It is important to note that “flange” refers to the flat surface or rim that supports the toilet and connects it with the drainage system. Installation often requires placing the wax ring on the flange before positioning the toilet, ensuring a proper fit.
Certain conditions can contribute to the need for a wax ring flange. If the toilet is not installed correctly, it may wobble or shift. Over time, this can cause the wax ring to compress unevenly, leading to leaks. For example, if the floor beneath the toilet is uneven, it could disrupt the seal. Homes with fluctuating temperatures may also experience issues, as extreme heat can cause the wax to become brittle or deteriorate over time.
