How will you know if your radon mitigation fan is working?

You must check the manometer to know if your radon mitigation fan is working. A red liquid substance is outside the device, which works as an indicator. If the fan stops working, this device will have a U-shape. When the fan is running and working properly, this device shows a J-shape. The pressure created by the fan speed determines the shape inside the manometer. When the fluid in the manometer is higher on one side and lower on the other, it works fine. If you still have some doubts, call your service provider to get it checked. 

This radon mitigation manometer is absent in a passive system. Why? There is no running fan in this system; hence no indicator device is present.

How long does a radon mitigation fan usually last?

According to National Radon Defense, radon mitigation fans generally have a 5-year warranty. But with proper maintenance, they can last for more than 20 years. Depending on the quality of the fan, its lifespan can expand. It is advisable that if you keep the fan working at a low speed, its lifespan improves. The other factors impacting its lifespan are proper installation and external weather conditions.  

What affects the lifespan of the radon mitigation fan?

  • The temperature of the attic

Sometimes extreme temperatures inside the attic affect the radon mitigation fan. Extreme heat can put extra pressure on the fan and cause it to break down sooner. 

  • Moisture 

If you turn off the fan for some time, the moisture from the soil and the concrete starts to seep inside the fan. This directly affects the longevity of the device and causes damage. Or if you live in a damp place, then this can happen even without turning off the fan. Get your fan occasionally checked if you live in a damp area.
