This 12-H15 model has a 2.1-gallon capacity, stands about 12-1\/2 inches tall with an 8-inch diameter, and features a 1\/2-inch system connection with a ship weight of roughly 4.25 pounds. The tank uses a carbon steel shell with an FDA-grade polypropylene liner to keep the water from contacting the shell, helping protect water quality and durability. A Schrader valve at the bottom allows quick checking or adjustment of the tank’s air pre-charge to ensure proper operation.\u003c\/p\u003e\u003c\/div\u003e","brand":"Backstop","offers":[{"title":"New","offer_id":51660476809518,"sku":null,"price":54.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_00d6bcab-b9bc-4690-84ff-56a3bd5f74a7.jpg?v=1769538076","url":"https:\/\/plgautomation.com\/products\/industrial-12-h15-hydronic-heating-safety-tank","provider":"PLG Automation ","version":"1.0","type":"link"}
