Air admittance valve is an important component in modern plumbing systems, designed to maintain correct air balance within the drainage network while preventing sewer gases from entering the building.
It allows air to enter the system when negative pressure occurs, helping waste water flow efficiently and reducing the risk of trap seals being disturbed.
