Failure to do so could prevent the proper operation of the Zero valve resulting in colder areas of a system being damaged by freezing. The Anti-vacuum valve must be kept clear at all times, Intatec recommend using the ZEROGUARD anti-vacuum cover (inspected on annual service).\u003c\/span\u003e\u003c\/p\u003e","brand":"Inta","offers":[{"title":"Default Title","offer_id":55325477372280,"sku":"AFCOMPACKSW","price":282.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0799\/5523\/1002\/files\/Inta_Anti-Freeze_Professional_Installer_Pack.jpg?v=1761041516","url":"https:\/\/heatpumpparts.co.uk\/products\/inta-anti-freeze-professional-installer-pack","provider":"Heat Pump Parts","version":"1.0","type":"link"}
