How to Know If Your Drain Is Clogged

Not sure if your drain is clogged? Here are the most reliable warning signs — and what to do before calling a plumber.

5 Signs Your Drain Is Clogged

• Water drains slowly — the most reliable sign. More than 30 seconds to drain a full sink means a partial blockage is building.
• Gurgling sounds from the drain or nearby fixtures — air trapped behind a blockage.
• Water backing up in a tub or floor drain when you run another fixture.
• Foul odors from the drain — trapped food, grease, or sewage gas.
• Multiple slow drains at once — this means a main sewer line issue requiring rooter service.
