When is it time to swap out old pipes?

“Ended up chasing leaks in new spots every few months.”

That’s the classic sign the pipes are just done. Here’s how I usually break it down:

- If you’re seeing leaks pop up in different spots, the whole system’s likely corroded inside.
- Patch jobs can buy a little time, but you’re just delaying the inevitable (and racking up more drywall repairs).
- Once you’re opening walls, it’s way more cost-effective to swap all the old lines at once.
- Galvanized especially - when it goes, it goes everywhere.

Honestly, replacing everything now saves a ton of hassle and money long-term. Drywall dust is rough, but random leaks are a nightmare.

Honestly, chasing leaks feels like playing whack-a-mole - except with water damage instead of prizes. I get wanting to patch and move on, but after the third or fourth mystery drip, I started thinking about the bigger picture. Here’s how I tackled it (with a healthy dose of caution):

1. Map out every spot you’ve patched. If there’s a pattern, or if it’s just all over, that’s your red flag.
2. Check for weird water pressure changes or rusty water - sometimes the leaks are hiding behind the walls.
3. Once I hit two leaks in different rooms in a year, I called it. No more patching.
4. Before tearing into anything, I shut off the main and double-checked for any live wires around where I’d be working (paranoid, but better than zapping myself).
5. Got a pro to confirm my suspicions before going full demo mode.

I tried to DIY as much as possible, but honestly, the peace of mind after a full repipe was worth every bit of drywall dust. My only regret? Not doing it sooner... and maybe not buying stock in joint compound first.

Couldn’t agree more on the peace of mind after a full repipe. I kept patching for years, thinking I was saving resources, but honestly, all those “quick fixes” just wasted more water in the long run. Once I swapped everything for PEX, leaks vanished and my water bill actually dropped. Sometimes you just gotta bite the bullet before things get worse.

Funny, I was stubborn about sticking with copper for a while - thought it’d last longer, less plastic, etc. But after the third ceiling stain in two years, I realized patch jobs were just throwing good money after bad. I get wanting to save cash, but chasing leaks gets old fast, especially when tenants start calling at 2am about water on the floor.

I did a full PEX repipe in one of my older duplexes last year. Not only did the random leaks stop, but I swear the pressure’s better now too. I still wonder if I should’ve done it sooner, honestly. That “bite the bullet” moment is different for everyone, but for me, once repairs started eating into my weekends, that was it. Sometimes you really do have to stop patching and just fix the root problem.

Honestly, I was in the same boat - kept patching copper way longer than I should’ve. Here’s how I look at it now: if you’re dealing with more than one leak a year, especially in older buildings, it’s time to start budgeting for a full repipe. PEX isn’t perfect, but it’s way easier to work with and less hassle when you need to make changes down the road. I used to think copper would outlast me, but after chasing pinhole leaks and dealing with water stains, I’m not so sure anymore. The peace of mind alone is worth it, especially if you’ve got tenants.
