Anyone ever regret not just biting the bullet and moving the drain, or is this just part of homeownership?
Honestly, I wrestled with this exact thing during my last bathroom update. Here’s how I weighed it out:
1. If you’re already opening up the wall or floor, moving the drain isn’t as big a deal as it seems—just more mess and cost.
2. If you leave it zig-zagged, you’re probably fine for a while, but leaks love weird angles and stress points.
3. From an eco angle, fewer joints = less risk of leaks = less wasted water down the line.
I ended up moving mine after a slow leak ruined some old particleboard. Not fun, but now I don’t worry every time I stash cleaning supplies under there. If you can swing it, straightening things out is worth it in the long run... but yeah, feels like classic homeownership headaches either way.
Moving the drain is one of those things that feels like a pain in the moment, but pays off later. I’ve had a few units where previous owners did the “zig-zag” approach and, like you said, leaks always seem to find those weird angles.

Couldn’t agree more. In my experience, tenants rarely notice a slow drip until it’s already caused damage—especially if there’s stuff stored under the sink. I usually bite the bullet and move the drain if I’m already opening things up. It’s not just about leaks either; straight runs make future repairs way easier. Less time tracing pipes through odd turns.
One thing I’d add: if you’re dealing with old galvanized or cast iron, sometimes moving the drain is actually safer than disturbing brittle joints trying to “make it work.” Costs more up front, but less risk of emergency calls down the road. Just part of keeping things low-maintenance... or as low as they ever get in rentals.
Funny timing—just went through this exact headache last month. Our bathroom sink is off-center because the previous owner tried to squeeze in a wider vanity without moving the drain. The result? A weird S-shaped pipe that looked like it was trying to win a limbo contest. I figured, “How bad could it be?” and left it for a while.
Fast forward a few weeks, and I noticed a musty smell under the sink. Pulled everything out and, sure enough, there was a slow drip right at one of those awkward bends. The pipe wasn’t even cracked, just stressed from being forced into that angle. I guess pipes don’t like yoga as much as people do.
Here’s what I ended up doing, step by step:
1. Cleared out the cabinet and took photos of the setup (helpful for reference).
2. Shut off the water and put a bucket under the trap.
3. Disassembled the zig-zag mess—took way longer than I thought because some joints were stuck.
4. Measured where the drain *should* go for a straight shot down from the sink.
5. Cut and dry-fit new PVC pieces to make sure everything lined up.
6. Used a flexible coupling to connect to the old cast iron in the wall (that part made me nervous, but it worked).
7. Double-checked for leaks before putting everything back.
It was a pain, but now it’s a straight run and I can actually see what’s going on under there. I get why people try to avoid moving drains—it’s not fun—but honestly, I’d rather deal with it once than keep mopping up mystery puddles.
One thing I’ll say: if you’re not comfortable cutting into old pipes, it might be worth getting help. I got lucky, but I could see how brittle cast iron could turn into a bigger mess fast.
Anyway, lesson learned... sometimes shortcuts just aren’t worth it, even if they seem easier at first.
That’s a huge win getting rid of that S-pipe mess. I totally get the hesitation with old cast iron—sometimes I worry about what’s lurking behind my own walls. Did you notice any mold or water damage under the cabinet? I’m always paranoid about that stuff, especially with slow leaks. You did the right thing fixing it properly instead of just patching it up. Shortcuts can come back to bite you, especially with plumbing... and water waste is no joke either.

Totally agree with this. I learned the hard way in my old place—thought a little duct tape would hold a leak for “just a bit.” Ended up with a warped cabinet and a musty smell that never really went away. You did the smart thing fixing it right the first time. It’s not fun, but at least you know it’s solid now.
