My whole house smell like dirty sewer throughout. It's a 1971 but we remodeled it one month ago. The inspector said there is a leak in one of the tubes in the crawl space. One of our bathroom clogs up very easily and we can't use the shower because water starts to build up and doesn't get through. We have a little whole in the wall after ripping out a cabinet in the kitchen. Now it's still empty because we will install an over the range microwave. When someone takes a shower, in the next wall over, there is such a disgusting smell coming out of that whole in the wall. Is all of this caused by the leak in the tube or is something very wrong? Also, the toilet bubbles after flushing.

Also, the toilet bubbles after flushing. And there's your smell. Those bubbles are sewer gas. You have a partial blockage downstream from the toilet. This can be addressed in several ways.
1- Pull the toilet and snake from there **OR**
2- You can snake from the shower drain.
Repair the leak in the crawl space before it starts to turn into mold underneath it, Good luck, Tom
