The problem is that they do not install venting, all plumbing for sewage and grey water should be vented to the exterior, roof,by installing traps and teed into a venting pipe, but they seldom do. By teeing in to venting ting pipe 2" you will also have better drain flow. Methane sewage gas is detrimental to your health.

Air is one thing wastewater is the other. Seriously go after the polluters and hit them in the pocketbook heavily, that will get their attention. It needs to be done now

At the same time don't forget the overhead signs.
