Anti-siphon valves (also called vented loops or siphon breaks) stop seawater from being siphoned back into engines, generators, toilets and bilges after equipment shuts down.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Both operate automatically, but both need regular cleaning and inspection. A neglected anti-siphon valve is the most common cause of generator and engine hydrolock.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Applies generally<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Valve quantities, sizes, makes and locations vary by model, hull and build specification. Always confirm against your vessel&#8217;s plumbing schematics, as-built drawings and equipment manufacturer manuals. On classed vessels (e.g., RINA), class requirements take precedence.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><a>1. What they are<\/a><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><a>Check valve (non-return valve)<\/a><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A one-way valve that lets water flow in one direction and closes automatically against reverse flow.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Swing check:<\/strong> hinged flapper; orientation-sensitive. Larger seawater and bilge lines.<\/li>\n\n\n\n<li><strong>Spring \/ inline check:<\/strong> spring-loaded poppet; any orientation. Fresh water and pump outlets.<\/li>\n\n\n\n<li><strong>Joker \/ duckbill:<\/strong> flexible rubber valve. Toilets and sanitation pumps.<\/li>\n\n\n\n<li><strong>Screw-down non-return (SDNR):<\/strong> can be closed by hand, otherwise acts as a check. Class-compliant bilge manifolds.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><a>Anti-siphon valve (vented loop)<\/a><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A valve at the top of a raised loop of hose. It stays closed while the line is under pressure. When the pump or engine stops, it opens to air and breaks any siphon that would draw seawater back into the equipment or vessel.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Vented loop:<\/strong> the raised hose loop plus the valve at its crown.<\/li>\n\n\n\n<li><strong>Remote vent:<\/strong> a small hose from the valve to a safe location above the waterline, used where the valve would otherwise weep water into the space.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>They are not interchangeable<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A check valve stops reverse flow but does <strong>not<\/strong> prevent siphoning, and it can stick open or closed without warning when fouled. An anti-siphon valve breaks a siphon. Never substitute one for the other.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><a>2. Where they are fitted<\/a><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Typical applications on Ocean Alexander yachts. Not every vessel has every item.

How to test<\/a><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Before removing any valve<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Close the associated seacock and confirm it holds. Isolate the pump or equipment electrically. Relieve pressure on fresh water systems. Wear gloves and eye protection on sanitation systems.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><a>Anti-siphon valve function test<\/a><\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Confirm the engine or generator is shut down and cool.<\/li>\n\n\n\n<li>Remove the valve cap or element per the maker&#8217;s instructions.<\/li>\n\n\n\n<li>Inspect the seat and element. It should be clean, flexible and free of salt crystals or cracks.<\/li>\n\n\n\n<li>Blow gently through the valve from the hose side. It should seal. Apply light suction from the hose side. It should open freely.<\/li>\n\n\n\n<li>Reinstall, start the equipment and confirm there is no continuous weeping.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\"><a>Check valve backflow test<\/a><\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Run the pump to establish flow, then stop it.<\/li>\n\n\n\n<li>Watch the upstream side (bilge, sump or pump inlet). No water should run back.<\/li>\n\n\n\n<li>Where accessible, close the seacock, remove the valve and apply water from the downstream side. It must hold.<\/li>\n\n\n\n<li>Move the flapper or poppet by hand.
