Removing bolts from toilet flange


I narrowed down a toilet leak from under the toilet on floor to most likely coming from wax seal or flange so I bought a new wax and removed toilet. To remove the toilet, I had to cut the bolts with a hacksaw, after which, the old wax ring was mostly still attached to the bottom of the toilet and a small bit of wax remained on the pvc flange.

The pvc flange was basically flush with the flooring but just a bit crooked...a little lower in the back & higher in the front. I couldn't get the bolts out so I had to remove the pvc flange, which was apparently sitting in what looks like a bed of caulk on top of the original cast iron flange, which the bolts are attached to.

What's the best way to remove the bolts & approach this repair moving forward?

FWIW, the laminate flooring in this room will be replaced with tile sooner rather than later.

Any access under the flooring?
Really need to get rid of any of that old cast that you can before it starts leaking and closing up.

No access under the flooring, if you mean like basement access.

Removing bolts from toilet flange


are those bolts threaded into the flange? Will those nuts come loose. Tear up the floor, or the ceiling.

Some one ran nuts & washers down to the CI flange to hold them rigid- not uncommon. Use you saw to cut them off or hold the bolt with channel locks then try to spin the nuts up. You may have to cut at some point.
Also, remove the caulking as best you can. The piece you pulled off is a spacer ring to allow for adjustments in floor hieghts.

Thanks! Looks like one bolt is threaded to the flange, if not both. I'll try to get the caulking as best I can and see what the bolts & flange look like underneath. If I do have to cut, where's best to make the cut?

The Cast Iron is gone. What do you mean there is "No Access" There is always access, some is just easier than others. That pipe has to be replaced. You cannot polish a turd.

Removing bolts from toilet flange


Once I got the caulk out, the bolts just slid right out.
Everything seems to be intact but here's what I'm left with now:

Removing bolts from toilet flange


Take the rag out and show up a picture of the inside of that pipe. The inside of a pipe that has to carry toilet paper, feces, hair and whatever else anyone decides to throw into the toilet needs to be smooth. That pipe looks like it is very badly scaled inside, and will tend to catch all of the aforementioned. Now is the time to fix it, IMHO. What exactly is keeping you from doing so? I hope its not Sheetrock, especially since you are planning to tile the floor.

OK, here you go; I took the rag out & put a little tp down inside.

It wasn't my fault!
... I ran out of gas. ...I had a flat tire. I didn't have enough money for cab fare. My tux didn't come back from the cleaners. An old friend came in from out of town. Someone stole my car. There was an earthquake. A terrible flood. Locusts! IT WASN'T MY FAULT, I SWEAR TO GOD!

Seriously though, with a little help from ya'll, WE'RE DOING IT!

There's no Sheetrock that I'm aware of to be concerned about and yes, I do plan to tile floor but just not prepared to right now. I'm hoping this isn't too major a DIY fix or expense and I could at least get the leak stopped and the toilet up & running again until I'm prepared to tile the floor.

The reason I said I hope its not sheet rock is because sheetrock is very easy to replace, and it would be crazy not to do it right if that is the case. Is this a concrete floor, is it a wood floor, is it a second floor bathroom, a first floor bathroom on a slab, what is preventing you from getting under the floor to access the pipe to replace it, that is the question.

Personally, I think your pipe is fine, it's the flange that I worry about. It looks weak around the slots plus, it's set a little low.
You could go with this gasket flange (or similar model) and push it into the existing pipe and anchor it to the slab. This would give you new anchor points for the toilet bolts and also raise it some.
Another option is just a repair flange

Thanks. Ideally, how high should it be set?

How would that type of gasket flange affect the fact that it's set a little low...should I still need to put back all the caulk & the spacer ring, too?

...and how would it affect things when I go to replace the flooring with tile sooner rather than later?

FWIW:
I took a wire brush to the cast iron flange especially around the slots, then tapped around a bit with a screw driver and it all seems pretty solid.
