Troubleshooting: Broken Toilet Flange or Improper Installation Troubleshooting: Broken Toilet Flange or Improper Installation

A broken toilet flange causes the toilet to malfunction, as does improper installation. Knowing the difference is quite helpful. The flange is the piece of pipe that connects the toilet to the waste pipe. Old toilets typically have a cast iron flange, while new toilets have flanges made from PVC. Follow this advice to troubleshoot for a broken flange.

Flange Is Too Low or Too High

The problem can sometimes be caused because the flange is either too low or too high. This problem is usually the result of poor installation. If the toilet flange is below floor level, then screw-in extenders can be used raise it. If the flange is too high, a toilet plate which can be used to lift entire toilet slightly.

Checking the Toilet

The toilet flange should not become damaged, because it doesn't move. The only way the flange will become damaged is if the toilet wobbles. Replace the flange and correct the wobble.

Visual Inspection

Inspecting the flange should help you determine the problem. If it is broken or damaged, you will notice.

Replacing the Flange

Decide whether to replace the whole flange or simply use a reinforcer. Reinforcers are clipped over part of the flange for extra support. If you are working with a PVC flange, adding a reinforcer will be very simple. Cast iron flanges can be much more complicated to reinforce.

It's not possible to connect cast iron directly to PVC. Buy an adapter to connect the parts of the flange. Once the flange is repaired, ensure that the toilet is securely bolted down.
