Tightening the bolts that connect the toilet bowl to the floor?

[Warpy]

8. Ouch. I was lucky I only had to pee in a bucket for a few days

before I got someone out to get mine sorted--drain clearing, new loo, new wax seal, new connections. The new low flow toilets are so much better than the old stinker I had in this old house. Best of all, the new one isn't kiddie height, an advantage for an old broad with a bad back.

I agree that when it starts rocking, it really needs to be checked out. I was lucky that the cast iron flange was OK in mine. When the thing starts to rock it can mean that's rusted or cracked, that there are floor problems, and other possible problems no sane person without specialized tools wants to tackle. Been there, also, ancient Boston apartment.

As for the ceramic covers, they were never really connected to any toilet I had and just lifted off, exposing the bolts and nuts below. While you can attempt to tighten a nut that feels a little loose, don't tighten it down hard or you might find out why it loosened up on you and that can run into serious money.

FWIW, I'll replace the guts inside a toilet but I hate plumbing problems like poison and will pay an expert his weight in gold to take care of anything else.
