What size vent pipe for a bungalow?

The size of the vent pipe for a bungalow typically depends on the Plumbing system's total drainage load and local building codes. Generally, a 2-inch diameter vent pipe is sufficient for a single bathroom, while a 3-inch diameter is often recommended for larger systems or multiple fixtures. It's essential to consult local plumbing codes and consider the specific requirements of your plumbing layout to ensure proper venting and compliance.
