How To Activate a Passive Radon System
What is Passive Radon System?
A passive radon system is a radon system without the radon exhaust fan. A passive system typically runs from the basement sump crock or drain tile and exhausts through the roof, without the use of an active radon exhaust fan. Passive radon systems rely on what’s referred to as a “stack effect”.
How To Activate a Passive Radon System
Passive radon systems can be activated to reduce radon levels by installing a radon specific, in-line fan. These fans create suction within the system that draws radon gas out of the soil and vents it above the home. Passive systems can only be activated if the were originally installed correctly.
Frequently Asked Questions
What is the primary difference between an active and a passive radon system?
Passive subslab suction is the same as active subslab suction except it relies on natural pressure differentials and air currents instead of a fan to draw radon up from below the home. Passive subslab suction is usually associated with radon- resistant features installed in newly constructed homes.

Can you add a fan to a passive radon system?
If you happen to have a passive radon mitigation system, be sure to test your radon levels to check whether or not it’s working effectively. If your radon test comes back above the EPA standard, it’s best to activate the system by adding on a radon fan.
Why is my radon system not working?
Check the electrical circuit that powers your radon system to ensure that the circuit did not trip. If the fan is installed in the attic, check to make sure that it did not come unplugged. If the fan is installed on the exterior, check the electric box next to the fan and ensure that the switch is in the “on” position.
What is a passive mitigation system?
Passive mitigation is defined in § 68.3 as “equipment, devices, or technologies that function without human, mechanical, or other energy input.” Passive mitigation systems include building enclosures, dikes, and containment walls.
Should I get an active or passive radon system?
Greater Reliability: Passive radon mitigation systems can be easily rendered ineffective with improper installation or even minor changes. An active system is far more robust and will remove radon from your home regardless of what might happen over time.
How do I know my radon system is working?
The first way is to regularly check the manometer (U-tube) that should be installed on the pipe of the system either in the basement or in the garage. The second way is to re-test your home every two years with a simple charcoal radon test kit.
What is a passive radon detection device?
Passive devices require no electrical power and generally trap radon or its daughter products for later analysis by a laboratory. Passive devices include charcoal canisters, charcoal liquid scintillation detectors, alpha track detectors and electret ion detectors.
Can I turn a radon system off and on?
Radon fans run continuously and while NRPP requirements call for a disconnect switch, the fans should never be turned off.
Do radon systems run all the time?
The radon fan needs to run continuously in order for the system to work properly. Radon systems are unlike other mechanicals in your home such as your furnace or air conditioner as they don’t require annual cleanings or tune ups. They do however require that some attention be paid.
