3. Rice, pasta and other expanding foods
Rice, pasta and bread are all troublemakers. They’re like those little toys that magically expand into a big, fun, toy dinosaur after they’ve soaked in water for a while. The difference here is that the toys are fun, while rice or pasta expanding in your drains is the opposite of fun. These foods also tend to leave starchy residue, which can lead to problems. Throw them in the garbage, instead of the drain, and you should be in the clear.
