When a toilet rocks like a rocking chair, leaks water around the floor connection or displays other signs of insecure foundation, the toilet flange needs replaced or reset. A toilet flange is the metal plate located below the toilet which connects the toilet with the sewer outlet pipe while securing the toilet with the floor. When a toilet is initially constructed it is secured to the floor with screws and the junction is sealed with a liberal application of beeswax.

When a toilet is securely fastened and maintained properly, proper function including no water leakage or odor present is the norm and not the exception. An indication of possible need of attention is the presence of black mold on the floor near the base of the toilet. Also evidence of water leakage or an unpleasant odor originating from the toilet base is a reliable indicator of the need for a toilet flange repair.

Regardless of who does the repair of a toilet flange, the following criterion is paramount for a job well done. It is also important to follow certain procedures, from diagnosis to completion of the job.

Tools and materials: screws, screw driver, flange bolts, wax rings, caulk and a flange repair kit.

Remove the Toilet: After shutting the water supply to the toilet, flush the toilet water from the tank and bowl before releasing the toilet from its floor connection. Unscrew the bolts and nuts on the sides of the toilet base. Secure the bowl and tank and lift the toilet from the floor connection.

Repair the Toilet Flange: Old wax must be cleaned off from the old flange. Flange bolts may need replaced due to corrosion from water leakage. Position the flange bolts in the holes of the repair kit and place it on the floor as the previous flange setup. This step ensures proper placement of the flange and prevent leakage.

Fix the Flange and Toilet: Follow manual instructions of the original toilet manufacturer when screwing the flange to the floor. Place wax rings and remount the toilet with bolts and nuts.

How do you repair a broken ABS toilet flange in a concrete basement floor?

The flange is there mainly to anchor the toilet to the floor. There is a replacement or repair ring available to fix this kind of problem. They are either brass or steel. Cut the rest of the ABS flange off flush with the floor and install the new ring by screwing it down to the floor with either concrete plugs and screws or there are screws available that will screw directly into the concrete. Make sure the new ring is in the right place so that the slots for the toilet anchor bolts are on the sides of the hole.


How do you repair toilet bowl mounting flange?

depending on your type of flange and pipe and the damage of the flange, if you have a PVC flange with just the bolt slots busted then you can screw in new bolts to the floor below the flange and still use the flange but if its broken where the wax seal sits then if your flange is lower then the floor you can use a insert flange that fits inside your old toilet flange with thin walls to keep the pipe size maximum. To replace the entire flange can be a job especially if its in concrete or in a floor joist because most of the time you have no room and if its cast iron pipe it can be even more of headache but in order to replace the flange you need to cut it out to where you can reconnect the pipe and flange by using a fernco or a no hub band. Sometimes it is impossible to replace because the flange can be on all close fittings and you pretty much have to replace most of the plumbing drain pipe to replace it properly which is why you want to try repairing your toilet flange rather then replacing it .
