Gotta disagree with you there. I've seen this exact thing happen with clean installs and fresh checkpoints where there's zero chance of cache issues or accidental style prompts bleeding through.

Oh man, does that sound familiar? I tried to swap out a toilet flapper once - one of those easy ten minute jobs - and ended up having to replace the entire fill valve because the old one snapped clean off when I took the flapper off. The water was spraying everywhere while I was sitting there with a wet shirt trying to find the main shut off. I swear, every time I think something will be quick, the pipes have other plans. You're not alone in that 6 hour nightmare, trust me.

My grandpa was a carpenter and he always said the sawdust piles in his shop told him more about a project than the finished piece ever could. What about those weird lumps in old plaster walls you find during renovations, are those ancient repair jobs or something else entirely?

Did you find yourself using the same supplies or did that change too? I went through a whole phase where I only used colored pencil and now I can't stand the look of it.

Were those old injection pumps actually less efficient from a fuel delivery standpoint or just built tougher to handle the lower pressure?
