We’ve got an imperfectly functioning toilet mechanism. It’s not a problem with the seals, and my wife and I both think it’s not going to require popping off the tank to fix it. I have the parts I need, and I’ll tackle the job after lunch. It’ll either be a half hour job, or all day today and tomorrow. Wish me luck!
[UPDATE: Well, I had to pop out for a proper wrench. But everything SEEMS to be working all right, now. Giving it a couple of hours to break entertainingly, though.]
