Clogged Toilet: Causes, Fixes & When to Call a Plumber
Use a toilet plunger (flange-style, not cup-style) with firm up-and-down strokes for 30 seconds. If the toilet won't clear after 3–4 attempts, a toilet auger ($20–$50) reaches deeper blockages. Call a plumber if the toilet overflows or multiple toilets are clogged.
What Causes Clogged Toilet?
- Excessive toilet paper
- Flushable wipes (they don't break down)
- Foreign objects (toys, hygiene products)
- Low-flow toilet struggling with waste
- Main sewer line blockage affecting multiple toilets

Frequently Asked Questions About Clogged Toilet
- No — despite the label, flushable wipes do not dissolve like toilet paper. They accumulate in sewer lines and are a leading cause of drain blockages and sewer backups. Never flush wipes, even those labeled "flushable."
- Recurring clogs usually indicate a partial blockage deeper in the drain line, a buildup of wipes or foreign material, or a drain pipe with too little slope. A plumber can camera-inspect the line to identify the cause.
- Use a flange plunger (has an inner flap that extends into the drain). Insert it so the flange fits into the drain opening. Push and pull with firm, equal strokes for 20–30 seconds. The pull stroke is as important as the push.
