My mom learned the adage "if it isn't broken, don't fix it" the hard way. She had a plumber come in to inspect everything and make sure it was working as well as it should. We had done business with him for many years, but this time he brought his idiot son with him, who decided that the hefty all-metal mechanism that had worked in this toilet for decades had to be replaced with this cheap plastic garbage. By the time I saw what was happening, it was too late.
What happened is the flapper started hanging on the hollow vertical tube it's attached to. I tried filing down the joint where it was hanging, and that worked for a bit, then it started hanging again. Then I realized what was happening is that the flapper piece itself was shrinking alarmingly fast, and now doesn't even align properly with the drain hole anymore. So the toilet will run every so often to replace the water that leaks through the improperly sealed drain.
What I want to know is if high-quality standard-toilet mechanisms are still made, and whether I can buy them and just hire someone to install precisely what I want them to install. I'm thinking GPW here, but anyone who knows more about this stuff than I do (and since I can trust everyone here) is more than welcome to give me some feedback.
Edit: I checked online and realized I can probably replace just the flapper piece itself. The toilet is an American Standard. There's still so much I don't know, though, and all the mechanisms I see are these same compact plasticky things. Damn it. Why has everything gotten so cheap (and not in a good way)?
