Have you ever tried using one of those inspection cameras?
Tried one once—ended up mostly filming my own confused face and a lot of cobwebs. My house is old enough that the pipes seem to run wherever they feel like. Last time I poked around, I found a newspaper from 1952 stuffed in the wall. Not sure if it was insulation or just someone’s lunch break reading material. Sometimes I think the pipes are holding the place together more than the studs are...
Inspection cameras are handy, but yeah, they can turn into a weird selfie session fast. Old houses are a maze—I've seen pipes that seem to be on their own secret mission. That newspaper insulation trick was actually kind of common back in the day. Sometimes it's fun to see what folks left behind, but most of the time, it just means more stuff to work around.
From what I've seen, DIY with a camera is great for spotting obvious blockages or leaks, but when pipes start running wild behind plaster and mystery layers, that's when things get tricky. It's not just about finding a problem; sometimes you need to know how the whole system fits together, especially in older places where "standard" wasn't really a thing yet.
If you're comfortable poking around and have patience for a little trial and error, DIY can be fine. But when the pipes look like spaghetti and you start finding ancient artifacts, calling in someone who's seen it all might save some headaches... and maybe keep the house standing another 70 years.

Not sure I totally agree that calling in a pro is always the best move once things get complicated. I mean, yeah, old houses can throw some real curveballs—like you said, “pipes that seem to be on their own secret mission”—but sometimes that’s exactly why DIY can be worth it. When you’re working on an older place, you get to know the quirks of your house firsthand. That’s pretty valuable if you’re planning any eco-friendly upgrades down the line.
Here’s how I usually tackle it:
1. Map out what you can see—sketch or snap pics as you go.
2. Use the inspection camera for the obvious stuff (blockages, leaks).
3. If you hit something weird (like newspaper insulation or mystery pipes), pause and research before tearing into anything.
4. Only call in a pro if you spot something truly hazardous (asbestos, major corrosion, etc.) or if you’re stumped after some solid effort.
I’ve found that taking it step by step keeps things manageable and helps avoid unnecessary costs. Plus, learning your own system makes future repairs less intimidating. Just my two cents—sometimes a little patience and curiosity go further than folks think.
Totally get where you’re coming from—half the fun (or terror?) of old house plumbing is discovering those “what were they thinking?” moments. I’d add: labeling everything as you go saves a ton of headaches later. I learned that the hard way with a mystery shutoff valve… still not sure what it does.
That mystery shutoff valve thing cracks me up—every old house seems to have at least one. I once found a valve in a crawlspace that literally did nothing. Turned it, waited, nothing happened... still no clue. I’m with you on labeling, though. It’s saved me from a few “why is the water off in the bathroom but not the kitchen?” moments. Honestly, I lean toward DIY for basic stuff, but if you’re staring down a tangle of pipes and mystery valves, sometimes it’s worth calling in someone who’s seen it all before.
