💡 What is an air admittance valve used for?

An air admittance valve helps maintain proper atmospheric pressure within your drainage system to prevent sewer gases from backing up into your home or vehicle. These handy devices work without needing a roof vent extension making them perfect for remote locations like trailers or interior room additions. They open automatically when water flows to balance pressure then seal tight immediately after to stop foul odors. Installing one ensures your sink shower or washing machine drains function smoothly without trapping annoying smells inside your space. ✝️
