In the colder months, a lot of people tend to gravitate more toward heavier comfort foods, with a lot of fat or grease. The unfortunate result is that drains more frequently get clogged up during these times, which can cause long-term damage to piping or other parts of the home if overflowing occurs. This is why there’s an important rule that must always be followed when dealing with fat and grease. Never, ever, ever pour it down a drain or otherwise let it get into your plumbing system. The main reason for this is that as fat cools down, it turns into a solid mass that collects other debris passing by it. Of course, you can guess what this would mean for your pipes. So, be sure to wait until the fat or grease solidifies naturally in the air, then throw it away with your garbage before using the sink again.
