A really crappy situation... (rusted out flange+more)

[Spoolofpipe]

Thought I was out of the plumbing business, was helping my wife clean the kitchen, I look up and see a water ring in the ceiling. The upstairs bathroom is directly over out kitchen.

Got the ladder out and went to see if the drywall was wet, my finger poked all the way through, so I cut out the ceiling dry wall and started troubleshooting, I could see that the subfloor was damp, so I went upstairs, pulled the toilet and found the tallest wax ring stack I have ever seen.

The toilet flange was a good 5/8" under the finished tile floor. Its a PVC pipe with a metal ring that was almost completely rusted out.

So my plan was to get one of those flange relocation kits with spacers and a repair flange, and bring up the flange to the finished floor

But looks like the subfloor wood on the side where it was leaking is a tad mushy. Screws were spinning

I dont want to pull the tile upstairs, what is the move here?
Reinforce from below?

I was thinking to get my heat gun and make sure to really dry out the subfloor from above and below

then put a couple of 2x4s running from the wall to the truss between the floors.

Am I crazy?

Thanks in advance

Repair ring. There are different kinds. Some have ears, and you drill holes thru the tile. Drilling holes thru ceramic tile is a little hard. Drilling holes thru porcelain tiles is a lot hard.

Danco Hydroseat is also a possibility.

Note that vigorous plunging into a clogged pipe can blow wax out.

Thanks for the input, my flange is one of those PVC ones with the galvanized ring around it
I went to the store and picked up a split ring flange (https://oateyassetscdn.azureedge.net/assets/Image/large_038753427775_INFO_001.jpg)

my plan was to raise the pipe itself, but wouldnt budge, I peeked my head into the ceiling space and its pinned between one of the diagonal truss members and a 2x4, so guess I will have to use the full set-rite kit

So on this toilet, we never had any clogging issues, so never had to plunge or use the snake on it, but it is one of those newer low water consumption toilets, so wonder if just the rusty flange plus the water velocity stressed the wax enough to make it fail, the toilet looked pretty centered on the wax when I pulled it.

If you do use the extender kit, use silicone sealant/adhesive between pieces.

Toto 1.6gpf -- Long Term Leak

I am the original owner of a house bought in 2003. Dec 2008 I discovered a large water stain in the kitchen ceiling. I also noticed the hardwood floor beneath the stain was cupping. I cut out various areas of drywall and discovered rotted wood beneath what appears to be waste piping from the...

Closet Flange Extension Kit Question

Over a decade ago I installed a BruCo Closet flange extension kit to raise the flange due to a tile installation. The bathroom has been used very little and we are putting it back in regular service with a new Toto Drake II toilet. The original kit was installed with the first flange sealed to...

The two purposes of a closet flange are to provide a seal, and to hold down the toilet. If your new potential configuration does not look reliably up to the hold-down job, you could use a repair ring with ears. Your proposed repair ring should hold the toilet down fine as long as the ring is held down well, and the closet bolts are long enough to cover the distance.

When you set a toilet, it is normal to use shims to prevent rocking. Before placing the wax, set the toilet in place, and place shims to prevent rocking. Lift the toilet, leaving the shims in place (or mark them to restore them). Then place the wax, and then place the toilet. Wax does not work well when you expand it even a bit, as will occur with rocking. It squishes great.

Look at Danco perfect seal or 7530 fluidmaster seal
