Such siphoning may be prevented by fitting the V-ASDH at least 40cm above the waterline.\u003cbr\u003e\nThe Vetus ASDH air vent is ideal for toilets or holding tanks which are installed below the waterline. The anti-siphon vent comes complete with a skin fitting, hose clamps, and 4m of breather hose. Features a hose connection to the outside of the hull. There is a constant bleed off of cooling water through this hose, whilst the engine is running. Can be easily dismantled by hand for cleaning.\u003cbr\u003e\nFor hose ID sizes: 1\/2\" (13mm), 3\/4\" (19mm), 1\" (25mm), 1-1\/4\" (32mm).\u003c\/p\u003e","brand":"Vetus","offers":[{"title":"Default Title","offer_id":68052364361952,"sku":"V-ASDH","price":224.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0622\/2358\/1408\/files\/v-asdh_a98aba00-34b5-433d-93f9-852119f5fda3.jpg?v=1792526270","url":"https:\/\/www.carouselstore.co.uk\/products\/vetus-asdh-anti-siphon-air-vent-with-hose-and-fittings-13mm-32mm-v-asdh","provider":"Carousel Store","version":"1.0","type":"link"}
