A 3 or 4 inch pipe sticking straight up out of the ground? This is the clean out for the sewer line. If sewage is coming out of it, this means the sewer line is clogged or collapsed from there to the main city sewer. If you have a septic tank, the tank is full and needs to be pumped out.

For a residence with two toilets, a 4-inch diameter sewer line is typically recommended. This size accommodates wastewater from multiple fixtures and ensures proper drainage and flow. Depending on local plumbing codes and the overall layout of the plumbing system, a 3-inch line may be acceptable for smaller systems, but a 4-inch line is generally preferred for optimal performance and future expansion. Always consult local regulations and a plumbing professional for specific requirements.
The length of a 4-inch line is 4-inches.
A 45-degree sweep for a 4-inch sewer line is a fitting that allows for a gradual change in direction, minimizing flow resistance and reducing the risk of blockages. It features a smooth, curved design that shifts the flow of wastewater at a 45-degree angle, rather than making a sharp turn. This design helps maintain proper flow rates and is commonly used in plumbing systems to facilitate better drainage. The fitting typically has a diameter of 4 inches to match the sewer line it connects to.

First there should be no reason the a home needs a 4 inch waste line. Three inch is more then enough. But if you insist use a "consentric' reducer as opposed to the " "ecentric". Other wise your waste will have to jump up from the four inch , and you will have back up.
