A faulty or broken flange may be attributed to a loose or worn-out wax seal. However, flaws in the foundation, like an uneven floor, may also cause the toilet's base to leak.
Chances are your toilet flange (also called closet flange) is broken or deteriorating because it wasn't installed properly. Although rather common, a damaged toilet flange must be repaired as soon as possible to prevent leaks that could cause serious damage to your flooring or tile.
For example, it may break or crack. This is more common if your toilet is loose and rocks back and forth. Eventually, this pressure and stress can cause a full break that will need toilet flange replacement. Also, in some cases your flange may corrode, rust, or deteriorate.
If your toilet is creaking or wobbling, you may need to replace the flange. For a plumber, replacing a toilet flange is a quick and easy job. Replacing a toilet flange costs $145 to $165 on average.
Flanges last for about 5-20 years. Worn-out flanges will no longer create a tight seal between the toilet and outflow pipe. As a result, when you flush, the toilet will leak at the base.
Final answer: A cracked mounting flange is commonly caused by impact loading and loose mounting brackets, which can create undue stress and vibration. Faulty ignition timing and excessive torque on mounting bolts are less likely to directly cause cracking.
Improper flange alignment, especially flange face parallelism, causes uneven gasket compression, local crushing, and can cause subsequent leakage. Improper flange centerline alignment can also cause uneven gasket compression and flange leaks. Improper Gasket Centering.
Various damage to the flanges is in the form of external and internal scratches, scaling, weld spatters, protrusions, and dirt. Also, the flanges with warped seating surfaces increase the chances of leakage. It may lead to uneven gasket compression and ultimately results in flange leakage.
The flange is the metal coupling on top of the wax ring that secures your toilet to the floor and seals the connection between the toilet and sewer pipe. If either piece becomes worn or broken, you'll likely have a leak on your hands.
Sometimes the lever arm becomes corroded and rusted to the point of breaking, especially for those with hard water.
Common indicators of flange problems include: Water Leaking at the Base: Water pooling around the toilet base after flushing is a telltale sign that your flange needs replacing, especially if the water is dirty.
Cracked or Broken Flange: Years of wear and tear or excessive pressure can lead to cracks or breaks in the flange, causing leaks. Improper Installation: If the flange isn't set correctly on the floor or isn't aligned with the toilet base, it can lead to gaps and subsequent leaks.
PVC flange, the most common type of flange, simply lift it from the outflow pipe. If the flange is metal or glued to the drain pipe and cannot lift out once the bolts are removed, call a licensed plumber to remove it for you.

These durable systems can be used to protect most flange shapes, sizes or configurations from corrosion and completely encapsulate the flange to exclude any moisture.
To fix this issue, it is crucial to follow proper installation procedures. This includes ensuring that the flange faces are parallel and in contact with each other, using the appropriate gasket material, tightening the bolts in the correct sequence and torque, and applying a suitable sealant or lubricant.
A faulty or broken flange may be attributed to a loose or worn-out wax seal. However, flaws in the foundation, like an uneven floor, may also cause the toilet's base to leak.
Flange or Shield | Replace every 6 months
Keep an eye out for cracks, warping, and residue build-up, and replace immediately if you notice this. For hygiene reasons, replace at 6 months.
A broken flange can cause your toilet to move because it is no longer secured to the flange, which is anchored to the subfloor. The rocking can cause the wax seal between the toilet and the flange to break, allowing water to leak onto the substrate and the ceiling below when the toilet is flushed.
Most common causes of flanged joint failures
Improper material selection: Choosing flanges, gaskets or fasteners that are incompatible with the process fluid or operating conditions can lead to corrosion, erosion, elongation, and, ultimately, failure.
Cracking often appears during welding or immediately following solidification and is often evidenced as centerline cracks running longitudinally (along the main length) along the weld. Some smaller peripheral longitudinal cracking may also present itself in the weld.
Labor accounts for $75 to $300 for a simple flange replacement, while the toilet flange and wax ring materials cost $10 to $50. Complex flange replacements or projects that involve water damage repairs have higher costs. *Many plumbers have minimum job fees of $100 to $200.
Here are some signs that you should call a plumber to take a look: Wobbly toilet: If your toilet rocks back and forth or feels unstable when you sit on it, this could mean the flange isn't holding the fixture down securely. The instability can further damage the flange and cause leaks.
There may be several reasons you have a wobbly toilet. It may not actually be the entire toilet that's wobbly, either; you may just have a loose seat that needs tightened or replaced. However, you could have worn-out caulking, loose or damaged bolts, or a toilet flange in serious need of some TLC.
