How large is the Property Service Connection leading out of the house?

Kingston asked:

I was just wondering, approximately how large is the Property Service Connection that leads out of the house? The Property Service Connection is the pipe that goes from your house (it’s essentially the main drainage pipe that leads out of the house, from the sinks, bathtubs, toilets, etc.)
So does anyone have an approximation of how large the diameter is?

Most places are either 3 inch or 4 inch pipe

These are inside diameter measurements

It depends on the number of plumbing fixtures and “bathroom groups” you have. On most newer homes, 4″ is the minimum.
