Default Help! Horrible Basement Smell

We have a horrible odor in our unfinished portion of our basement, it is like a motor oil or 'shop' type smell. Our furnance / ac was looked at and we were told it wasn't that. It isn't our sump pump, washer or dryer. We had the floor drain snaked yesterday and the smell went away for about 18 hours. Now it is back and just as strong. Any ideas on what it could be and how I can get rid of it??

Welcome to the site. Is your floor drain attached to city sewer or your septic tank, does it have a trap. Do the other plumbing traps have water in them. Have you herd strange noises from the drains when you run water?

Hand dishwashing detergent cuts grease. See if some of that into your drain also gives you some relief for a few hours.

Maybe a neighbor dumped motor oil into a storm drain.

We do have traps on the drains and we made sure they have water in them. The floor drain is connected to the main city sewer line and we haven't heard any weird noises.

Someone suggested an animal might have crawled into and died in our furnace or water heater exhaust but I would think that would be more of a rotten smell than a mechanical smell.

Hopefully you don't have furnace oil tank in the basement. Any history of furnace oil stored on the property or near by.

Put a bucket over the drain and see if the smell goes away.

Not all of these

are safe.
Maybe the Health Dept. can give you some ideas.

Also, some fumes at some concentrations are explosive.

Is the smell stronger close to the ground?

There is a point when it becomes too thick to ignite.

If you are sure that is coming from the drain, put a venting pipe over it going to out side air. Why not try a longer snake, if it worked once try again.

This might be about the same time that the air won't support life.
