Televised sewer from pulled toilet for smell coming into basement. There was no backup nor breaks in the line and could not see any obvious areas where smell could be coming from. There is one area with a slightly separated joint but could not say definitively that this is the area. Basement is unfinished and there is going to be reconstruction done. It is suggested that the sewer be dug and replaced to the main line that leads out to the city. This line all looked good.
