{"product_id":"drainage-air-admittance-valve","title":"Drainage Air Admittance Valve","description":"\u003cp\u003eAir admittance valves in 40\/50 mm for waste and 110 mm for soil. The valve lets air into the pipe to break the vacuum that would otherwise siphon a trap dry, without needing a vent pipe up through the roof. Check before ordering: It admits air but does not let foul air out, so it cannot replace the main soil vent. It must also stay accessible — a valve buried in a sealed void cannot be replaced.\u003c\/p\u003e","brand":"Tal-Ħaddiema","offers":[{"title":"40\/50 mm · Waste pipe","offer_id":64515280699769,"sku":"DRAI-AIR-ADMI-VALV-40-50-MM-WASTE-VAL","price":8.95,"currency_code":"EUR","in_stock":true},{"title":"110 mm · Soil pipe","offer_id":64515280732537,"sku":"DRAI-AIR-ADMI-VALV-110-MM-SOIL-VALVE","price":19.5,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1035\/8593\/9833\/files\/77893_a6fc5cee-5249-4bfd-a906-acefe63b9a62.jpg?v=1788945419","url":"https:\/\/tal-haddiema.com\/products\/drainage-air-admittance-valve","provider":"Tal-Ħaddiema Hardware Store","version":"1.0","type":"link"}
