	To maintain stability in a drainage system, it is necessary to alleviate this change in air pressure immediately. This response time is paramount for protecting water trap seals, with traditional secondary pipework systems thought to be the only way to provide this function.

		+	== Considerations for designing drainage and ventilation ==

	There are many factors to consider when installing secondary pipework systems, which continue to be the industry norm. For Instance, installing a secondary stack ventilation system requires more installation time and materials, and in turn takes up valuable floor space, a major factor when limited space is taken into consideration. With architects often designing buildings to a small footprint, particularly in city centres with limited space, the inclusion of a secondary stack can hinder the design process.

	Secondary venting also proves to be a much less effective solution for very tall, or complicated, drainage systems as the time lag that occurs when communicating a change in ambient airflow in the pipework can result in an ill-performing drainage system. This would require expensive maintenance and repair throughout the life of the system.
