"Stop up" is a phrase that means blocking or closing something. You can use it when talking about blocking a drain or stopping up a hole in a tire. For example, if you have a leaky faucet, you might want to stop up the hole with a piece of tape to keep water from dripping out. It's a useful expression to know when you need to describe preventing something from coming out of a container or closing off a passage.
