The Seaflo vented anti-siphon valve is a secure solution against siphoning and backflow in onboard hose systems. It breaks the water column, preventing unwanted backflow.
The anti-siphon valve is installed at the highest point of the system (typically 20–50 cm above the waterline) and is often used with marine toilets, septic tanks, and bilge pumps, where it increases safety and reduces the risk of water damage.
