Foul smell from soil pipe?

I live in a 3-storey house with 4 bathrooms. Recently I started noticing a quite unpleasant smell in the bathrooms on the 1st and 2nd floors. It seems to be coming from the toilet but, as we do keep our toilets and bathrooms very clean, the only likely source of that smell must be the soil pipe behind. Is it a signal to me that I need smth checked/cleaned/flushed? How do I deal with this? Is it likely to be a big problem requiring a complete overhaul of the piping, or can it be done quite economically? Your advice would be greatly appreciated.

You'll need to check for leaks that let sewer gas into the house. Like the floor settled causing the wax seal under the toilet to lose contact either with the toilet or with the flange. Or the oakum seal between sections of soil pipe deteriorating or cracking. Or maybe a rat got trapped somewhere in the floor or wall and died there.


States can help recovery from hurricanes and tornadoes by not requiring due digence or prompt and timely correction of substandard conditions, and by providing continued liability insurance where companies drop homeowners.

I agree with AllanJ. The odor is probably sewer gas, and the only way it can enter the room is by a bad wax seal or a broken pipe.
If you have never made a mistake, you haven't done much.

My thoughts, too - it's better to check or replace the little things, first - because they need to be replaced, anyway, after a long while of use. . . and if that doesn't take care of it then move onto the more costly or intensive things.
At this present moment in time I am making cabinets for the kitchen - just in case you wanted to know what I'm doing when I'm not around.
