An anti-siphon valve prevents backflow of water into the drinking water supply. It is typically installed above the highest point in the system and uses a one-way valve to allow water to flow in only one direction, preventing contamination. When water pressure drops, the valve closes to prevent backflow.


Strings attached to AV cusps?

Strings or chordae tendineae are attached to the atrioventricular (AV) valve cusps within the heart. These structures help to anchor the valve leaflets in place and prevent them from prolapsing back into the atria during ventricular contraction. Dysfunction of the chordae tendineae can lead to regurgitation of blood flow across the valves.
