Identifying a Rusted Toilet Flange

How to tell if your toilet flange is rusted

There are a few ways to tell if your toilet flange is rusted.

• Rusty stains: If you see rusty stains around the base of your toilet, it’s a good indication that the flange is rusted.
• Leaks: If you notice water leaking from under your toilet, it’s possible that the flange is leaking. To check for a leak, turn off the water supply to the toilet and place a bucket under the toilet. Flush the toilet and see if any water leaks out.
• Loose toilet: If your toilet is loose, it may be because the flange is rusted and no longer providing a secure hold for the toilet. To check if your toilet is loose, try rocking it back and forth. If it moves more than a few millimeters, it’s likely that the flange is rusted.

What causes a toilet flange to rust

There are a few things that can cause a toilet flange to rust.

• Water: The most common cause of a rusted toilet flange is water. When water sits on the flange for long periods of time, it can corrode the metal and cause it to rust.
• Corrosion: Corrosion is another common cause of a rusted toilet flange. Corrosion occurs when metal is exposed to chemicals, such as acids or salts. These chemicals can eat away at the metal and cause it to rust.
• Age: Age can also cause a toilet flange to rust. As the flange ages, the metal can become weaker and more susceptible to rust.
