Not a fun post here. We’re remodeling the kitchen and primary bathroom in our 1940 home. The rough plumbing was finished about two weeks ago.

For at least 10 days now we’ve smelled wafts of sewage. We assumed it was a plumbing vent open from the bathroom work. But the smell was coming from under the crawl space and getting stronger.

DH investigated today and found a good amount of raw sewage coming straight from our mater bath toilet, and we tested and indeed from the bath tub as well (so assuming sinks and shower in there too). We and our small boys are all using the master bath since the main bath is under construction.

The plumbing under the master is new build as of 4 years ago. Is it merely ca coincidence that the contractor had the plumbing work for the remodel done at the same time the sewage pipe broke or is it possible that his subs busted something under there?

Ughhhhh any advice?
