I've bought an old house, and I've decided to fix a rocking toilet. I found two flange repair kits stacked on top of the original broken toilet flange. When sawing the flange to remove it, I found the entire pipe moves inside the floor.
Well as I was sawing the flange the riser pipe came out of the 90 degree joint. I've also noticed standing water in the pipe, so I'm guessing the end I'm looking at is sitting lower than the tee.
I intend to buy a straight section of pipe and a new flange, but am I correct in assuming that having a toilet flange hold up a section of pipe is asking for disaster? I'm thinking I will have to open up the ceiling below and add a hanger. Or am I overthinking this problem?
