Question: What could be causing my toilet not to flush properly?
Answer: If you notice that your toilet isn’t flushing correctly, then there could be a number of things making it behave that way. Some of these include worn-out toilet parts, a clogged sewer line, or even a clogged vent line. Call a plumber to inspect and rectify the issue for you.
