The -50°C rating gives a meaningful safety margin over the -40°C products common on shelves, which matters in a cold snap or if some dilution from residual water is unavoidable.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon issues:\u003c\/strong\u003e The most frequent winterization mistake is draining the main freshwater tank and assuming the job is done — pumps, water heaters, foot valves, and low spots in the plumbing almost always retain water and will freeze if antifreeze doesn’t reach them. Circulate until you see antifreeze coming out of every tap and fixture. Also confirm you have the right product — this 9.46 L plumbing antifreeze (063-9925-6) is a different SKU from the 3.78 L marine water system antifreeze (063-9922-2) and the 3.78 L RV antifreeze (063-9910-0).\u003c\/p\u003e","brand":"CNT","offers":[{"title":"Default Title","offer_id":43563780276260,"sku":"063-9925-6","price":25.7,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/18cf9fdc-1286-4149-9894-7fcb361da03b.png?v=1788824195","url":"https:\/\/marisolmarine.com\/products\/winterproof-plumbing-antifreeze-50c-9-46l-063-9925-6","provider":"Marisol Marine Company","version":"1.0","type":"link"}
