Is Radon Fan Working? Radon Testing & Radon Mitigation in MD, VA, DC

Step 1. Find your system MANOMETER. A manometer is a U-shaped tube filled with fluid(red, blue, yellow), it is also called Gage Fluid. It’s a visual gauge that tells you if your radon fan is running and at what static pressure.

Where is manometer ?

All active radon systems with fan usually will have a manometer. It is mounted on the pipe BELOW the Fan or next the the collection point. ( usually in the basement, closet, attic or garage )The exception is a passive radon reduction system, it does not have fan, not manometer.

Is the manometer showing radon level?

Answer is NO. Manometer has nothing to do with Radon level in the house. Manometer is measuring pressure (suction power) of the system. The suction created by the radon fan draws the fluid up on one side of the gauge. One side on manometer will have a clear soft tube which connects manometer and radon vent pipe. The other side on manometer is left open( its normal, it must be open. do not close it).

Step 2. Check the fluid levels. Are they Different? if YES, that’s good! The radon fan is working. Call right away Radon Mitigation provider if levels have changed from the Initial installation level. When liquid level is higher or lower than original, it means system resistance has changed., something below or above the fan is not allowing air to move at the same volume . Are the fluid levels equal? This is not good; your radon fan is not operating.

Step 3. Check the Electrical power connection. Is Your Radon Fan Really Dead? There are several things that may have caused the fan to shut down and you’ll want to check before calling a radon contractor to replace the fan. Please make sure your fan has electrical power. Check fan electrical switch. Did the breaker that your radon fan is wired to trip? Is the fan unplugged? Touch radon pipe, place your ear next to the pipe. If it is not vibrating and not making suctions noise, it time to replace fan.

Unfortunately, the fan is an electrical component of the system, and it has its life span too. It won’t last forever and must be replaced once in a while to keep the radon system operational.

Alfa Air was recommended by a neighbor for Radon mitigation systems so I gave them a shot. They were prompt and professional, did a nice job with the install, and really reduced the radon levels in my finished basement. After the install they came back with special equipment to re-test the Radon so we could see the performance. I felt the price was also reasonable. I would recommend this provider to all.

we just found our dream home , but it had radon gas . we were so worry about family safety. I work from home and basement is my home office, where high radon gas was discovered during radon inspection. Luckily our realtor explained that radon can be mitigated. We contacted Alfa Air Agency, they have installed pipe network and fan to remove the radon gas. since our real estate contract was contingent on radon retest, we requested after mitigation a radon retest too. We were so nervous while waiting in 48h retest time. But all turned just fine , radon dropped a lot , now its same low as natural outdoor level.We are closing on our dream home in two weeks.

since pandemic I work in my basement, I never heard about radon , but I saw my neighbor has installed some new fan outside. it made me wonder what has happened to them.... thats how i learned about indoor radiation. who could imagine that my home basement office can be deadly dangerous. we cant see it, we can’t smell it, but radon causes cancer . its worth that smoking a pack of cigarets per day .I did my research and got diy radon test as a starter , results was around 7 pci/l .I could not believe that little test can be reliable, its just one sample of air, what if its wrong? Thats how I made my appointment with certified radon testing company Alfa Air for get my home basement tested for 48 h , so I can see the full picture, all 49 air radon samples I received a full radon test report same day as machine was picked up from my home.
