A client in Santa Clarita was doing her final home check list received from a local Realtor. She noticed that the master bathroom toilet was leaking at the base of the toilet. This job needed to be repaired immediately because this home was sold. There had been a recent earthquake in the area and the toilet had jump upwards and was not seating correctly on the bathroom floor.

This post shows the eleven steps needed to repair a damaged toilet flange with a quarter flange on a metal flange. 

Step 1: Above right purchase fig.1 shows a Fernco(™) Quarter Flange that will replace the damaged half of the broken toilet flange.   
Step 2: Fig.2 shows Turn off the water stop usually located on the left side if facing the toilet. But it doesn't matter what side it on, the valve must be turned off.

Step 3: Remove from the toilet the water feed line from the bottom of the toilet bowl. Fig.3 and fig.4 shows a white curled tubing coming from the stop valve follow the fill line to the bottom of the toilet bowl. Remove the plastic nut using a Channellocks® pliers

Step 4: Fig.5 and fig.6 shows the toilet screws on each side from the toilet base, now use a Crescent Wrench to twist off the nuts. Some models have two nuts to be removed per side.

Step 5: Fig.7 shows the rubber gloves that needs to be used to protect the hands. The use of rubber glove will give the grip necessary to handle the toilet. Now remove as much water from the toilet bowl and the trap of the toilet and empty the water into the sink. When the toilet is laid flat it will leak all over the floor so removing as much water as possible makes the job safe.

Step 6: Fig.8 shows that placing a tarp on the floor where the toilet will be turned over. This will protect the toilet and the floor from the wax seal on the bottom of the toilet.

Step 7: Fig.9 shows a new ABS black flange not hooked up to its metal piping. Fig.10 Shows another metal flange that needs to twist on and welded to its piping. The homeowner wanted a simpler repair. Fig.1 and fig.14 shows the quarter flange that will be used in this repair. All three flanges can be purchased at warehouse store (The Home Depot) or a Plumbing store.
Step 8: Fig.11 and fig.12 shows the toilet on its side and shows a heavy duty variable speed Rotary hammer drilling around the cement near the metal flange. Click here to get information on how to drill into cement with rotary hammer.

Step 9: Fig.13 and fig.14 shows the silver metal flange has been screwed on top of the metal flange so when the toilet bolt is in position it would hold the toilet on the right side of the tile. Plastic anchors were inserted into the newly drilled holes attaching the flange. Click here for a simple and quick installation of the toilet bolts by Fluidmaster.

 Step 10: Fig.15 shows a metal saw (hacksaw) that was used to cut the toilet bolts down to the stainless steel nuts.

Step 11: Fig.16 shows the toilet is in use again and the new owners are happy that this was a quick repair. The tile had to be replaced but that was done by someone else. Turned out the tile underneath the toilet was stable and did not need replacing.
