I think we just solved the problem. We recently bought a new rubber sink plunger and the rubber plunger smells like creosote. We think that may be the odor. I will check back if the smell doesn't go away. Now we wonder if there is any kind of spray that will neutralize that strong odor. Thanks again!

Thanks for the update. If the odor persists check for an AAV (mechanical vent) under the sink (see image)... could be that the spring mechanism failed and the AAV needs to be replaced (if present).

I'm betting on the new plunger, too!

Hi Sinkguy

If you reread the post, Leibrooknola said they think the smell they were concerned about is coming from the new PLUNGER and that if that wasn't the issue they would post back.

With that being said, however, I know about the insulation pad you are talking about... certainly could be the issue and if Leibrooknola returns the information you provided could prove useful so thanks for posting, for sure!
