What you're probably seeing
The bowl fills up or overflows when you flush.
Likely causes
- Too much paper or something that shouldn't be flushed.
- A blockage further down the line (if tubs or sinks gurgle too).
Safe checks you can do now
- Turn the valve behind the toilet clockwise to stop the water.
- Use a flange plunger with steady pushes.
- Don't flush again until it drains.
When to call a pro
Plunging doesn't clear it, or other drains back up.
