The answer to 'sink slow draining' is that a slow-draining sink is typically caused by a clogged drain. Common symptoms include water taking longer to drain, gurgling noises, or water backing up in the sink. The most common solutions are to try using a plunger or a drain snake to clear the clog, or to remove the sink drain and clean out any debris. If the clog is deeper in the pipes, you may need to call a professional plumber to use a motorized drain snake or hydro-jetting equipment to fully clear the blockage.
It's generally best to start with DIY methods like a plunger or drain snake, but if those don't work or the clog seems severe, it's a good idea to call in a licensed plumber to properly diagnose and fix the issue. Trying to force a stubborn clog can potentially cause more damage, so it's often safer to have a professional handle it.
