{"product_id":"928-103","title":"928-103","description":"This 1\/2-inch Hot Water Tank (HWT) Vacuum Relief Valve, also known as a vacuum breaker, is a critical safety component designed for pressurized water heating systems and boilers. It automatically vents the system to atmosphere when a vacuum is created, protecting the storage tank from structural damage or collapse caused by negative pressure. This valve is essential for preventing back-siphonage of contaminated water into the potable water supply during drainage or sudden pressure loss. Engineered for durability and reliable performance, it is a standard safety requirement for maintaining the integrity of hot water tanks, solar water heaters, and steam-supplied equipment.\u003cbr\u003e\nType: Boiler and Water Heater Safety Valve\u003cbr\u003e\nSize: 1\/2-inch NPT\u003cbr\u003e\nApplication: Residential and commercial water heaters, boilers, solar heating systems, and pressure vessels to prevent vacuum-induced tank failure and back-siphonage.\u003cbr\u003e\nSpecifications: 1\/2\" male NPT connection, automatic operation, atmospheric venting capability, suitable for hot water supply applications.","brand":"BCFurnace","offers":[{"title":"1\/2\" HWT VACUUM RELIEF VALVE (VACUUM BREAKER) \/ 928-103","offer_id":47251076579613,"sku":null,"price":39.97,"currency_code":"CAD","in_stock":true},{"title":"1\/2\" HWT VACUUM RELIEF VALVE (VACUUM BREAKER) \/ 1\/2\" N36M1-CAN","offer_id":47251076612381,"sku":null,"price":39.97,"currency_code":"CAD","in_stock":true},{"title":"1\/2\" HWT VACUUM RELIEF VALVE (VACUUM BREAKER) \/ 3284-653","offer_id":47251076677917,"sku":null,"price":39.97,"currency_code":"CAD","in_stock":true},{"title":"1\/2\" HWT VACUUM RELIEF VALVE (VACUUM BREAKER) \/ 3332098","offer_id":47251076808989,"sku":null,"price":39.97,"currency_code":"CAD","in_stock":true},{"title":"1\/2\" HWT VACUUM RELIEF VALVE (VACUUM BREAKER) \/ N36 M1","offer_id":47251076710685,"sku":null,"price":39.97,"currency_code":"CAD","in_stock":true},{"title":"1\/2\" HWT VACUUM RELIEF VALVE (VACUUM BREAKER) \/ N36-M1","offer_id":47251076743453,"sku":null,"price":39.97,"currency_code":"CAD","in_stock":true},{"title":"1\/2\" HWT VACUUM RELIEF VALVE (VACUUM BREAKER) \/ N36M1","offer_id":47251076776221,"sku":null,"price":39.97,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/c26ec2b0a69640a49c11b51803b24325.webp?v=1773957533","url":"https:\/\/bcfurnace.myshopify.com\/products\/928-103","provider":"BCFurnace","version":"1.0","type":"link"}
