Identifying a Rusted Toilet Flange

A rusted toilet flange is a common problem that can cause a number of issues, including leaks, water damage, and even structural problems. If you suspect that your toilet flange is rusted, there are a few things you can look for to confirm.

  • Leaks. The most obvious sign of a rusted toilet flange is a leak. If you see water pooling under your toilet, or if you notice water stains on your floor, it’s possible that the flange is leaking.
  • Sagging toilet. Another sign of a rusted toilet flange is a sagging toilet. If your toilet is sitting lower than it used to, or if it rocks back and forth when you sit on it, it’s possible that the flange is rusted and no longer supporting the weight of the toilet.
  • Damaged tiles. If you have tile flooring around your toilet, you may also notice damage to the tiles. This can be caused by water leaking from the flange and seeping down into the grout.

If you see any of these signs, it’s important to have your toilet flange inspected by a plumber. A rusted toilet flange can be a serious problem, and it’s important to fix it as soon as possible to prevent further damage.
