Hi everyone,

First, let me say thanks to everyone on this site...I think it's great you are all willing to share your knowledge and experience with DIYers like me. Not only do I like to save a few $$, but I like to make sure it is done right and have the satisfaction of doing it right myself.

I've been reading posts on this site for the past few days to get some advice on my current bathroom remodel. Things I have read come close, but I thought it might be best to see if some of you experienced folks could comment on my exact issue.

The old toilet in this room had a "seepage" out of one of the bolt holes in the base. I figured it needed a new wax ring, and might as well replace the toilet with a lower flow model like the new one in my other bathroom that works 10x better than this old 3.5 gal/flush beast. After carefully removing the toilet and scraping away to clean the flange, I found the following:

- The CI flange is broken where the closet bolt would hold on (coincidentally or not, broken on the side that "seeped")
- The floor is tiled, but the flange is above the floor, not sitting directly on it.
- The flange is not secured to the floor. At best, I see a strap holding it up from below. However, the run is very short to the stack, and I have read some posts that you don't need extra support becuase CI is so strong (is that true?)
- It looks like there was water leakage in the past, maybe even from the roof (around the vent stack), or maybe from the toilet seepage, or some other old problem that was fixed. But it looks fairly dry now. There is some greenish looking stuff around. I was NOT planning on ripping up the floor and changing out boards.

So, at first, I thought the CI is old and rusty, so I should just remove it to the stack and change all that to PVC (with a SS flange of course), bolted to the floor, sitting flat on the floor. Then, when I learned the complexities of CI removal, I'm having second thoughts.

Here are my questions:

Is this CI in good enough shape to last another 30 years?
Should I call a couple plumbers for advice / estimates?
Or should I just use a SS repair ring and set the new toilet with a standard ring and it will be fine?
Is it okay that the flange is not bolted down, given how close it is to the stack and the metal strap?
How can I tell if the water damage is still occurring? Is it okay to leave the wood AS IS?

I'll post some pictures shortly to make it easier for everyone to see what I am descibing.

I'm hoping in all of your experiences, you will be able to give me some confident advice.

Thanks!

Shawn
