I woke up this morning and noticed that the water in my kitchen sink is draining extremely slowly. At first I thought it was just a small clog, so I tried using a plunger and a store-bought drain cleaner, but nothing really changed. It’s getting worse throughout the day, and now I’m worried it might be something deeper in the plumbing system. Has anyone experienced this before, and how did you figure out whether it was a simple blockage or a more serious issue?
