Hello, A clog can make a pipe leak in time. The leak results from pressure, which builds up from the blockage. A normal clog could eventually damage a pipe if enough pressure builds up in the pipeline. To prevent clogs, always monitor what is put in the drain. If you're in doubt, use preventative products like a drain cleaner or a hair trap.
