“Sometimes it’s just a thirsty drain...”
That’s the truth. I’ve lost count of how many times tenants have called me in a panic over “gas leaks” or “toxic mold,” and it’s just a dry trap. Here’s my quick checklist: 1) Find every floor drain, sink, or shower you rarely use. 2) Pour a couple cups of water down each one every month or so. 3) If the smell lingers, check for leaks or cracks around the trap—sometimes old seals let sewer gas sneak in. It’s wild how often the simplest fix gets overlooked.
Funny how often it’s just a dry trap, right? I’ve seen folks tear half their basement apart before realizing all they needed was a jug of water. Sometimes, though, even after topping off the traps, that sulfur smell hangs around. Ever run into a situation where the vent stack was blocked by a bird’s nest or something weird? That one threw me for a loop the first time. Curious if anyone’s had a similar “not-so-obvious” culprit behind the stink...

Blocked vent stacks are sneaky, for sure. I’ve also seen a cracked drain line behind finished walls cause that same sulfur smell—took ages to track down since everything looked fine on the surface. Once, it was just a loose cleanout plug letting sewer gas seep in. Ever had a sump pit go funky and stink up the whole place? Sometimes it’s not even plumbing, just a dead critter somewhere you’d never expect...
Not sure I’d blame the sump pit right away—sometimes that rotten egg smell is from a dry floor drain trap. If the water evaporates, sewer gas comes right up. Quick check: pour a couple cups of water down every basement drain. That’s fixed more “mystery” odors than I can count.

That’s a good point about the floor drain traps drying out. I’ve definitely had that happen in my laundry room—one day it just started smelling funky, and a little water down the drain sorted it out. Still, I always wonder if there’s a way to keep those traps from drying up in the first place, especially if you don’t use the basement much. Is there some kind of cheap solution, like a cover or maybe pouring something other than water that lasts longer?
Also, has anyone ever had the smell come back even after refilling the traps? I did the water trick, but a week later, the smell was back. Makes me wonder if there’s something else going on, like a crack in the trap or maybe a venting issue. Just trying to avoid calling in a plumber if I can help it... those bills add up fast.
