You shouldn’t ever pour oil, fat or grease down a sink. Grease – such as the leftover grease in the pan after you cook burgers – will usually only stay in a liquid state when it’s subjected to high heat. Once the grease cools, it will congeal and clog your drain. A clogged sink can create other plumbing problems, such as a flooded basement.
If your kitchen drain becomes plugged with grease, you should first check to see if you have a grease trap. If so, you should be able to fix the problem by simply removing the trap and cleaning it out. If not, try pouring a good amount of boiling water mixed with vinegar and baking soda down the drain. This may help liquefy the grease and usher it through the pipes.
Still clogged? Head to the hardware store for a degreaser. If that doesn’t work, you’ll probably need to have a plumber come out and snake your pipes. Once everything’s cleared out, prevent a future occurrence of the problem by installing a grease trap and limiting the amount of grease you put down the drain.
