{"product_id":"do-it-best-1-1-2-inch-mip-mechanical-abs-vent-valve","title":"Do it Best 1-1\/2 Inch MIP Mechanical ABS Vent Valve","description":"Do it Best 1-1\/2 Inch MIP Mechanical ABS Vent Valve eliminates the need for expensive secondary vent stacks, making it a practical choice for various drainage applications. It is suitable for sinks, basins, tubs, showers, vanities, and washing machines, but should not be used for toilets. Featuring 1-1\/2\" male pipe threads, this vent valve is conveniently packed one per Do it card for easy handling. Each drainage system using a mechanical vent must include a main vent stack that vents to the atmosphere through the roof, specifically positioned to vent the water closet. For optimal performance, avoid installing the mechanical vent in a sealed wall cavity; it should be placed in a location that is readily accessible. Installation is limited to structures that do not exceed two stories in height and that do not have corrosive water.\n\nModel Number: 403636","brand":"Do it Best","offers":[{"title":"Default Title","offer_id":47937765867683,"sku":"403636","price":6.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/2469\/7763\/files\/e295adca62fcb521ae33ad2bea0d2321b7f0ef0c_403636_1_H.png?v=1785395269","url":"https:\/\/www.hartvillehardware.com\/products\/do-it-best-1-1-2-inch-mip-mechanical-abs-vent-valve","provider":"Hartville Hardware","version":"1.0","type":"link"}
