About a month ago, I fixed our outside cleanout valve because someone had hit it with a lawn mower. I poured some main line cleaner in it and replace the cap on it (like the guy at Home Depot said I needed to do) and I dug up most if not all of the contaminated soil around it. Since then I have been having a sewage smell enter my house, mainly when the a/c kicks on. Now that it is in triple digits, I am concerned that the smell will get worse. What can I do to fix it? What is the problem? Please help

Check the A/C air-handler. The condensate may be fouled.

Main Line Cleaner ??? Clean Out Valve??? Love those Folks at the big box stores as they teach you all these good things, while they sell you products that you may not require, but rather, make you feel good.
Why did you feel the need to use a Main Line Cleaner?
Best Wishes

Mainline cleaner? You on a septic system?
If that doesn't work I've got a new space-age product for you to try. It's called
SnaqueOyl - $29.95 a gallon. But wait! - if you act now......

Trace the condensate drain pipe from your A/C fan coil unit (indoor unit) to see where it drains out. If it is into a vent line in the attic this is where your smell is comming from. There should be a trap on the condensate pipe near the fan/coil unit ( if not install one) but if it is connected to your drain or vent piping that is where the smell is comming from most likely. Connecting condensate drains to the plumbing is a no-no unless done according to plumbing code. It is best to just run it to outdoors.

Make sure the cap is on tight. If part of the old cleanout cover fell into the main, it could have caused a partial blockage. If the cleaner you used backed up under your house it could have eaten a hole in some old pipe. If it is a pier and beam house, when your ac kicks on it is pulling the foul air from under the house. It is more likely a dry trap somewhere or condensate drain problem as the others have said.
