Do you know what happens when you pour hot liquid grease down the drain? You might think that it should run down the drain easily, but it really is one of the leading causes of drain clogs that you can find. The problem is that the cold water will turn the grease into a solid mass almost immediately, and then this will start collecting debris and build up into something that you will need a lot of work to remove.
So what can you do instead? Many homeowners have chosen to have a container near their stove where they will dump their grease and let it cool. Others leave it in the pan only to scrape it out after it coagulates. Some will even reuse the grease for cooking later on.
No matter what method you choose, they are all better options than clogging your drain up. It will save you time, headache, and even possibly money.
