Clogged Drain: When to Grab a Plunger and When to Call
Most single-drain clogs are DIY-friendly. Here's how to tell when the problem is bigger than a plunger.

A slow sink or tub usually means a clog in that fixture's trap or branch line. A plunger, a drain snake, or even a baking-soda flush can often clear it. If one fixture is slow and everything else drains normally, start with the plunger.
The warning signs of a bigger problem: multiple drains backing up at the same time, gurgling sounds from other fixtures when you run water, or water rising in a tub when the washing machine drains. Those symptoms point toward a shared branch or the main sewer line — that's drain cleaning or sewer-line territory, not DIY.
If the backup happens fast, smells like sewage, or affects a toilet, stop using water in the house and call a professional. Frequent repeat clogs in the same drain also deserve a camera inspection rather than another bottle of chemicals — chemical drain cleaners can damage pipes and rarely fix the real problem.
