A toilet flange is a type of plumbing link that connects your toilet bowl to the sewage line. This is an important link. It can be a real pain if this connection is damaged or badly installed. Once installed properly, the toilet flange utilizes a wax ring as a seal to secure the toilet and ensure no leakages.

Generally, a toilet flange is a round material with multiple perforations in it. Bolts and Screws are put through these openings, securing the flange to the ground and, therefore, the sewage drainage pipe. After that, the toilet is snugly attached to the flange.

Waste can travel through the toilet to the sewage line without leaking because an impermeable seal is produced. You won’t have to unnecessarily fret about the waste leaking into the surroundings and creating a mess. It would be a very unpleasant situation to have all that stinky human waste leaking out!

Common Problems With Flanges:


Blocked-up flanges can cause toilet floods. It’s a simple remedy if you can access the obstruction and have the right equipment to fix it. All it takes is a wire to open up the blockage.

However, if access to the blockage is out of the question and you can’t figure out what to do with the obstruction, you should contact a plumber because they know best.

Cracked Wax Ring:

A weak or cracked wax ring, which disrupts the watertight seal, is another typical cause of accumulating liquid in your toiler. The wax ring should act as a tight seal, so if it loosens, there’s going to be a big, big problem with your flange and toilet.

Changing a toilet’s wax ring is simple, but it’s critical to do it correctly to avoid the problem from occurring again. It is better to keep it airtight.

Change of Flooring:

A change of flooring is also a root cause of flange problems. When toilet flanges are tightened and flush with completed floors, they operate best. Installing the flange is a crucial step in refinishing a bathroom floor.

So, keep the toilet flanges in mind whenever you’re getting a new set of tiles or just renovating the washroom and changing the floors. To have an appropriate flange height, bring it to level using a flange extender.

Types of Toilet Flanges:

Of course, even flanges have various types. You’ll find that toilet flanges can be made up of all kinds of different materials such as PVC, stainless steel, brass, copper, etc.

Polyvinyl Chloride Toilet Flanges:

You’ll find that a vast majority of toilet flanges are made of plastic or PVC. These materials are pretty common in toilet flange construction, and even commercial toilets make use of these. These are used mainly because they’re durable. Still, they’re not as good as stainless steel toilet flanges when it comes to durability.

Cast Iron Toilet Flanges:

You can count on cast iron toilet flanges to rise to the top when it comes to strength. It’s iron, so it has to offer a robust and sturdy build. Unlike PVC pipes that might crack, cast iron flanges are crack-resistant and will not disintegrate. You won’t have to fret about constant replacements.

Stainless Steel Flanges:

Stainless steel toilet flanges offer a high degree of durability. They can better seal the toilet, so the chances of leakage are close to zero! These flanges will cost you away from more than PVC or plastic, but remember that they’re also offering better sealing. So for extra protection, you could invest in one of these.

There are other types, but the above three are the most common ones.

Signs that Your Flange is Damaged:

A moving toilet:

A major sign of a damaged toilet flange is rocking or shaking the toiler. A faulty flange may be causing your toilet to shake. Inspect all the bolts for tightness before lifting the commode from the flooring. Failure to tighten a loose toilet could cause significant damage to a flange that may not require replacement.

Bad Odor:

 If you have nasty odors lurking around in your bathroom but no leaks at the bottom of your toilet, the flange may have cracked.

Even if the flange is not entirely cracked, it could still be cracked a little bit which causes the smells to escape. Trust me, and it’s not a smell that is tolerable even for a minute! A damaged flange will probably allow waste to escape from the bottom of the toilet if it is not repaired.

Replacing a Toilet Flange:

For replacing a toilet flange, we would highly recommend that you get it done by a plumber or a professional. But if you’ve got a little plumbing experience or are curious to try it out, it’s not that hard!

If you wish to change the flange yourself, the components are inexpensive and can be found at any home improvement store for under $30.


  1. Locate the valve on the wall on the backside of the toilet and turn it clockwise to shut off the water supply.
  2. After you’ve turned it off, flush the toilet, allow for the bowl to refill. Then flush it again. Keep on flushing until it doesn’t work anymore. The purpose of this is to empty the water tank. Lay newspapers across the bathroom floor while the toilet is emptying.
  3. Now, carefully remove the two nuts from the bolts that connect the commode to the flange and the flooring. You can use tools like a wrench to unfasten the nuts. Set the bolts away but keep them in a safe place because you will need them again to reattach them to the toilet.
  4. It’s now time to lift the toilet from the floor. Lift it and carefully place it on top of the newspapers.
  5. Once you see the old wax seal, scrape it off using a knife.
  6. Take the screws that are on the exterior of the flange, and the flange will disconnect. Wash the flange and set it aside.
  7. Now take the old flange head to a hardware store and get another flange of the same diameter and measurements. Bring it home and fit it where the old one was. Make sure that that it fits correctly with no gaps.
  8. Screw it using nuts and bolts firmly. Fix a new wax seal on it.
  9. Now just lift the toilet, put it back in place, and you’ll be good to go!
