 You probably want to take it apart from underneath the sink cabinet. It's probably going to have a trap, the U-shaped pipe. If it doesn't, by the way, that's the source of your problem, but I'm sure it does. Take that trap apart and then really scrub the inside of that with some oxygenated bleach, and I think that that will kill that bacteria, and then the biogas will go away. Okay. Sounds like a lot of work, but I'll certainly give it a try. Hey, we never said it was going to be easy. No, nothing ever is, it seems like. All right, Yvonne, good luck with that project. Thanks so much for calling us at 888-MONEYPIT.
