A sewage ejector for a residential installation must be vented with what size vent?

The requirement for venting a sewage ejector in a residential installation is based on plumbing codes that specify the need for adequate venting to ensure proper air circulation and prevent negative pressure, which can lead to siphoning and adequate drainage of wastewater.

A 2-inch vent is typically adequate for venting a sewage ejector system. This size allows for the necessary air flow to mitigate pressure changes and enables the effective release of gases, such as methane, that could accumulate in a confined space. Proper venting is essential not only for functionality but also for safety and compliance with plumbing standards.

Following plumbing codes that dictate vent sizes helps maintain the efficiency and effectiveness of sewage ejector systems while adhering to safety regulations. This is why a 2-inch vent is specified for residential sewage ejector installations.
