You're spot on about galvanized pipes—seen a few nasty surprises myself. Had a job recently where the homeowner thought it was just a minor pressure issue, but when we opened things up, the corrosion was unreal. Ended up replacing way more pipe than expected. And that hidden tub story is wild... makes you wonder what people were thinking back then, huh? Good reminder to always expect the unexpected in plumbing.
Had a similar issue last summer—homeowner swore it was just a simple valve replacement. Once we got in there, found pipes so corroded they practically crumbled when touched. Galvanized pipes are sneaky like that. Honestly, older plumbing is always a gamble; you never really know what you're dealing with until it's staring you in the face. And yeah, some of these old setups make you scratch your head...guess plumbing standards were more like suggestions back then, lol.
Ran into something similar a couple years back—thought it was just sediment buildup at first. Ended up being ancient galvanized pipes choking the flow. Swapped them out for PEX, pressure improved instantly. Older plumbing is always full of surprises...and rarely the good kind, lol.

Haha, true. Also worth checking your pressure regulator valve if you have one—sometimes they fail or get clogged up. Had a similar issue last month, replaced mine and pressure stabilized nicely. Just be careful adjusting it...pressure spikes aren't fun.
Had a regulator valve issue once, replaced it but honestly didn't notice much difference. Pressure was still all over the place until I found a partially blocked pipe further down... old plumbing always has something else hiding.
