independently through the roof

The waste system for a grease interceptor is vented independently through the roof to ensure that any gases or odors generated within the grease interceptor are safely and effectively expelled outside the building. This method of venting helps to maintain air quality inside the building and prevents any buildup of harmful gases that can occur in confined spaces.

Venting through the roof is essential for proper airflow and to comply with plumbing codes, as it prevents back pressure and allows for a more efficient drainage system. Additionally, it prevents grease and other contaminants from clogging section of the venting system, which might occur if vented through other locations like walls or floors.

This independent venting approach is crucial for maintaining the functionality of the grease interceptor while adhering to safety and health regulations in plumbing systems.
