Check the radon fan is still running

Make sure the radon system is still pulling air: read the gauge on its pipe, listen for the fan, and test the air again from time to time.

7 steps

Tap a step to watch it again.

Find the radon system's pipe: a plastic pipe rising from the basement floor, usually with a small U-shaped gauge on it.
The liquid in the U should sit higher on one side than the other. Level on both sides means the fan isn't pulling.
Put a small piece of tape at the liquid's level, so next time you can see if it has moved.
Go to where the fan is, in the attic, the garage or outside by the pipe. You should hear a steady hum.
If it's silent, check that the fan's own switch near it is on and its plug is in, and that its breaker hasn't tripped.
Run a radon test kit every couple of years, and after any big renovation, to check the system still works.
If the gauge reads level, the fan stays silent, or a test comes back high, ask Handyman for a radon mitigation pro.
