Several houses have been build. The plumbing have been made by the builder and is largely encased in concrete. We can't inspect anything.
So far, we did not find any place where to rent a Plummer Camera, so we are navigating a little blind.
We know there are VENT problems on both, the Gray and Black water sewer that are mostly separate. However, most of the fix are relatively easy as the toilet and sink are on an exterior wall. The exception, the washing machine.
We did test the washing machine drain pipe. We did poor a gallon of water in it. The next day, using an electric fish and a rag, we were trying to find some water. After 10 feet down, we check the rag, and it was 99% dry. Very unlikely to have visited a P-Trap. That drain smell, another tell sign.
Now, the question is how to correct it considering that everything is in concrete.
1 - Use an AAV valve what is pretty common in this country.
2 - Use a Drain-loop and an AAV valve
3 - Put the P-Trap underground outside with the Vent to the roof. (Sorry if my design is a little funny. I did not load the pipe library in my CAD systems.)
In this country, you can use IPCC or Canadian Plumbing code or others recognize plumbing code of the USA or Canada. The joke is that nobody will verify anyway. There is no inspector.
