5 Signs Your Radon Mitigation System Isn't Working Properly
A radon mitigation system is one of the most effective ways to protect your home from elevated radon levels—but like any home system, it should be checked from time to time to ensure it's working as intended. If your system isn't performing properly, radon levels could rise without any obvious warning. Knowing what to look for can help you catch problems early and keep your family protected.
1. Your Radon Levels Have Increased
The most reliable way to know if your mitigation system is working is by testing your home for radon. If a follow-up test shows elevated radon levels, it may indicate that your system needs inspection, adjustment, or repair. Regular testing is recommended even after a mitigation system has been installed.
2. The System's Warning Device Indicates a Problem
Most radon mitigation systems include a U-tube manometer or another monitoring device that helps indicate whether the system is operating correctly. If the gauge readings appear abnormal or the warning indicator changes unexpectedly, it's time to have the system professionally evaluated.
3. You Notice Unusual Noises from the Fan
A properly functioning radon fan typically produces a consistent, low-level hum. Grinding, rattling, squealing, or other unusual sounds may signal that the fan is wearing out or developing mechanical issues. Addressing these problems early can help prevent complete system failure.
4. The Radon Fan Stops Running
The fan is the heart of your radon mitigation system. If it stops operating because of age, electrical issues, or component failure, the system can no longer effectively reduce radon gas beneath your home. If you suspect the fan isn't running, contact a qualified radon professional as soon as possible.
5. Your System Shows Signs of Physical Damage
Cracked or disconnected PVC piping, loose fittings, damaged seals, or visible wear around system components can reduce the effectiveness of your mitigation system. Regular visual inspections can help identify issues before they affect indoor radon levels.
Keep Your Home Protected
Even the best radon mitigation systems benefit from periodic inspections and routine radon testing. If you notice any of these warning signs—or it's simply been a while since your last radon test—having your system professionally inspected can provide peace of mind and ensure it's performing as designed.
