How to Remove Old Toilet Flange

Removing an Old Cast Iron Toilet Flange

1. Use a pry bar to check if the flange is already loosened and can be lifted right off.
2. If it’s still attached, you may need to break it off. Set a cold chisel on the outer edge of the flange, then firmly hit the chisel with a hammer. Be careful not to get too close to the inner edge of the flange to avoid damaging the waste pipe.
3. Push the flange upward using a pry bar. If it is still not loose enough, move to another section of the flange and keep trying to pry it up until it comes free.

Removing an Old PVC Toilet Flange

1. Get your internal pipe cutter and insert the small circular saw into the drill chuck. Set the drill in forward gear.
2. Use the internal pipe cutter to separate the flange from the waste line by cutting at the point where they meet, which are 3 to 4 inches from the flange’s opening.
3. When you have cut through the whole flange, lift it straight off the subfloor.

What to Remember

If you don’t have the proper tools or experience in using such tools, it would be best to ask help from someone who has experience or to get assistance from a professional rather than risk damaging your toilet’s fixtures and waste line.
