  Anti-siphon valves are crucial for preventing backflow, which can lead to contamination of the boat's internal tanks, as well as damage to the marine head and other components

How it works:
The anti-siphon valve prevents this backflow by maintaining a low-pressure zone, allowing the liquid to continue draining, preventing water from flowing back into the system
Why it's needed:
Siphoning can happen when water is being pumped out of a boat, and after the pump is turned off, water can continue to flow back into the boat through the intake line

Here's a more detailed explanation:
  • Function:
    The anti-siphon valve is a normally closed valve that ensures liquid continues to drain or empty, even when siphoning occurs due to the Venturi effect or a vacuum. 
    An anti-siphon valve, found in OMC Evinrude and Johnson outboards, prevents water from flowing back into the boat after a pump is turned off, a process called siphoning. This valve is essential for marine heads and intake lines to prevent water from flowing back into the boat, potentially causing damage or water contamination
