1/8th per inch
The maximum slope for a 3-inch sewer pipe is typically recommended to be 1/4 inch per foot (approximately 2% slope). This ensures adequate flow and prevents blockages while allowing for proper drainage. However, local building codes or regulations may vary, so it's essential to consult them for specific requirements in your area.
The recommended pitch for a drain pipe leading to the sewer system is typically 1/4 inch per foot (or about 2% slope). This slope ensures proper drainage and prevents clogs by allowing wastewater to flow smoothly through the pipe. In some cases, a pitch of 1/8 inch per foot may be acceptable for larger pipes, but maintaining the correct slope is crucial for effective drainage.
It really depends on your local building code, but 2% should be the minimum so that your pipe will be self-cleaning.

I would use 3 inch for that.
Yes. A reduction fitting can be used.
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.
The pitch of a sewer line refers to the slope or angle at which the pipe is installed to facilitate proper drainage. Typically, a sewer line should have a pitch of 1% to 2%, meaning a drop of 1 to 2 inches per 10 feet of pipe. This slope helps wastewater flow smoothly toward the municipal sewer system or septic tank, preventing clogs and ensuring efficient drainage. Proper pitch is crucial for maintaining a functional sewer system.
