1. I had to call a plumber because a toilet float was busted and I couldn’t remove it no matter how hard I tried. They came and “found” all sorts of things “wrong” and quoted me almost $4k. A quick visit to Google and 1 phone-a-friend showed that they were full of sheet. I finally had to break the overflow tube to get it off but successfully replaced it for $15.
It was replacing whole toilet and completely (and unnecessarily) disassemble the bathroom and main drain (loo, sink, shower) to “bring it to code.”
