5 Different Types of Toilet Flanges

5 types of toilet flanges to know about

Published By: admin

One of the most important components in any bathroom is the toilet. It’s position, shape, and even color can dictate the feel of an entire room. This blog post is a large compilation of different types of toilet flanges and their construction, so you might want to check it out if you’ve ever wondered which type your toilet uses!

Before learning what types of toilet flanges are available, what exactly are toilet flanges?

Every toilet flange on a bowl is designed to provide the flow of water from the bowl to the sewer. Depending on what kind of toilet and plumbing you have, there are numerous types that can be found.

What are the different types of toilet flanges?

Copper

Copper is a unique metal because it has the ability to form into different alloys when mixed with other metals, resulting in a range of advantages. These benefits include better conductivity and strength, as well as greater corrosion resistance, which is essential for all types of toilet flanges. Copper is also relatively inexpensive to manufacture, which makes it a popular choice for plumbing applications.

PVC

PVC is a type of plastic that is used in the manufacture of flanges. PVC was first produced by Bayer in Germany in 1872 and was originally intended for use as a medicinal compound. PVC toilet flanges are commonly used in both residential and commercial plumbing systems. This type of toilet flange comes in a few different forms—either completely made of PVC or with a metal top. These types of toilet flanges fit drainpipes that are three or four inches across.

Brass

Brass is one of the most commonly used types of toilet flanges. Like copper, brass is malleable and resistant to corrosion, which makes this material a great choice if you want a toilet flange that lasts.

Cast Iron

Cast iron flanges are meant to be used with cast iron pipes. Cast iron is extremely durable and resistant to damage. In some cases, it may be possible to repair a cast iron flange instead of replacing it completely.

Aluminum

Because it is lightweight, corrosion-resistant, and durable, aluminum is an excellent choice for your toilet flange. This metal will not rust or corrode, so it should last for years before needing to be replaced again. Some aluminum flanges are pure aluminum and others are manufactured with copper or zinc. While the pure aluminum type is generally better, both are suitable for use on your toilet.

How to Tell When a Toilet Flange Needs to Be Replaced

If you are not sure when your flange was last replaced, you can continue using it until it malfunctions, or if you want to avoid a mess, you can replace it to start fresh. A worn-out flange can cause a wide range of problems, including:

  • Leaking at the base of the toilet.
  • Loose toilet that rocks back and forth and may be unsecured.
  • Unpleasant smells coming from the sewer because of gases leaking through the seal.

If you notice any of these signs, it may be time to replace your toilet’s flange sooner rather than later.
