Septic smell

I just moved into this house last week. A couple of days after moving in, I began smelling sewer gas in the house. The previous owner disclosed a smell before but said they thought it was fixed. I narrowed the smell to the basement washing machine drain line. They had stopped using it and installed a new line mounted to the wall with its own separate vent. Its not tied to the house vent system or septic. The old original is a 2 inch galvanized located inside a concrete block wall. They had filled in the space with insulating foam. I narrowed the smell to that area. I dug our the foam and found the pipe uncapped. I put water down the pipe to ensure the p trap was full. It didnt stop the smell. I put in an expansion plug. It seemed to help but the smell came back. Its coming out of the wall around the receptacle and the area of the pipe. Im thinking the pipe is damaged at or below grade. Im considering pushing maybe a ball of foul down to the p trap and filling the pipe with concrete. Any suggestions? Oh, the previous owner said they had the system smoke tested and found no problem.

Well, you're asking strangers on the Internet about a smell in your home. One area we really can't help with since we can't see what you've got. I would investigate things further before just pouring concrete down a pipe. If the solution were that easy why wasn't the pipe simply capped?
