    Reaching the limits of what my nose can, and prefers not to smell. Wondering if someone can recommend a good meter that could possibly help me detect the source of an odd odor in my bathroom.

    I'm living in a high rise, talking to the engineer, there are no gas pipes in my building, so we are guessing what I am smelling is sewer gas. Engineer mentioned that could be a chance of a cracked pipe in the wall but before we get into that heavy wall tearing work, I should maybe look into the cheaper, easier options. I have replaced the wax ring around my toilet, checked my sink P-trap, and taped up my shower drain. Still the smell lingers. Oddly, the smell that lingers seems different from that whiff I get from the sewer drain when my face was unwillingly over it while I work the wax ring. The lingering smell had more of like a leaky gas stove kind of smell, but there are no gas pipes in my building so I'm just clueless at this point, maybe sewer gas smell varies depending on proximity?

    I removed the toilet once again, and this time taped a bunch of duct tape all over the toilet drain, sealing it up, just to confirm if the leaky smell remains. If it does, at least it will rule out the toilet, and any shoddy workmanship when I installed the wax ring. And if it still lingers, and with everything sealed up, I think I need some meter to find that leak for me. Looks like there are different kinds of meters online that sniff for specific chemicals and I don't want to end up with a useless gameboy, anyone have recommendation of what I should get?

    Much appreciated!

    A dead rat can have a sewer smell, and can linger for 3 or more weeks

    Thanks, I was wondering if something died but the smell has been around for close to 2 months since I've moved in. I'm on the 15th floor too, not sure how high rodents could go.

    I live with 3 females with long hair. Every once in a while, the bathroom starts to smell like sewer gases. That's my cue to get my snake and clear the sink and shower drain. I usually get a large hair ball with all the crap that you can imagine. Smell gone until next time.

    I sometimes pour bleach down the si k overflow to clear out the gunk from there too.

    +1 For what Chucky said ^

    I had a similar issue in my bathroom once. Just a shot in the dark but you may be experiencing a similar issue. It was driving me crazy trying to find the source of the smell. It turned out to be a plunger in the bathroom linen closet. It was the type with the flap (for lack of a technical term) that folds up inside the plunger. The flap had trapped some water (?) inside and began to brew some noxious concoction of god knows what. I didn't even attempt to recover the plunger, out in the trash it went.

    ...and today was the day. I leave them on the counter for one of them to dispose of.

    Can the engineer check the bathrooms above and below you? Can they do a smoke test? Did you check where the p-trap goes into the wall? I've had an unglued vent in the wall cause a terrible smell once that was really hard to find. Is there a clean out somewhere that was recently opened on not sealed good?
