Do I need a radon test if my fan is not running?
However, any time the fan isn't running you'll have the problem of some amount of radon leaking into your house. If you go that route, you should do a follow-up long-term radon test to see if you're just changing from one problem to another.
How do you insulate a Radon fan?
If the radon fan is located in the attic of the house or garage you can wrap the fan with fiberglass insulation. The air flowing through the fan will maintain the fan temperature.
Can I put a timer on my radon test?
(Of course, all of us with radon systems should do periodic long-term tests - thanks for the reminder!) If it is hard wired, you might contact an electrician to see if it could be modified to put on a timer.
Is radon running in Your 6 month old's room?
Our radon system is right under/outside our 6 month old's bedroom. Over the fall and winter I never heard it but now it is running a lot and it is very loud and it is affecting our daughter's sleeping. We never used the room she is in last spring so I do not know if it ran a lot last year.

Should radon mitigation system make noise?
Radon mitigation fans are powered by water-hardened motorized impellers for water resistance and rated for outdoor use. But sometimes you might hear it making noise. The fan's bearings that help to lubricate the motion and reduce the noise start to go bad.
Should you be able to hear radon fan?
If your radon fan is making a loud humming or whirring noise, there's a chance that it needs replaced. Most fans last 5-10 years, with some making it up to 20. However, it's not uncommon for them to get very loud before they finally quit. If your fan is abnormally loud, check your manometer.
How do I stop my radon fan from making noise?
The smaller the pipe size drawing air from under the membrane the quieter the air flow noise. To reduce sub-membrane noise, downsize the pipe under the membrane to a 2" pipe which can move up to 50 cfm or a 1.5 inch pipe that can move up to 35 cfm of air.
What does a radon detector sound like?
RadonAway RSA1 Radon System Alarm Sensing Modes: Sensing light blinks at 60-second intervals (3 flashes). Audible “beep” sounds and all lights illuminate when “Test” button is pressed.
How loud should radon fan be?
The best standard would that the air velocity should not be greater than 700 FPM (feet per minute). Excessive noise and back pressure is created when too much air is moved through the pipe. According to the best standard, a 3” pipe should move no more than 34 CFM before the system is too noisy and loses efficiency.
Are radon sumps noisy?
After a sump system has been installed, a radon measurement should be made to ensure that the radon levels have been reduced sufficiently. In most cases sump systems run relatively quietly, but sometimes noise is a problem. Noise is often due to air movement and not the fan.
Can you hear radon fan in attic?
Quieter radon systems. Although radon systems installed through the exterior are quiet, installing the fan inside attic space can prevent all noticable system noise.
Do radon fans use a lot of electricity?
RadonAway radon fans cost only pennies a day to operate. According to the U.S. Department of Energy, a typical U.S. household consumes about 11,000 kwh per year, costing an average of $1,034 annually (at $0.094 per kwh).
Why is my radon system gurgling?
I hear a gurgling noise in the radon system. What does this mean? That means that water is not draining away from the suction point. If you have a ground water sump pump, this might mean that you should inspect your sump pump to determine if the sump is working properly.
How do you know if your radon system is working?
You can use the u-tube manometer to determine if your system is working. Look at the liquid in the tube. If it is equal on both sides, it is an indication that there is no pressure in the pipe. This means no suction from the fan (far left image) and the radon mitigation system is not working.

Should I hear water in my radon pipe?
The radon pipe gurgle and sound like water because there is water stuck in the pipe or below the pipe . Some houses has very high water , which is collecting under foundation. Radon fan is powerful enough to pull some water into the pipe from below. This bubbles of air and water will make gurgle noise.
How long does it take for a radon fan to work?
What are the benefits of radon mitigation? The primary benefit is reducing the risk of developing lung cancer. Standard radon reduction systems are usually effective within 24 hours and maintain low levels as long as the fan is operating.

What to do if radon is making a noise?
If it’s making noises, it should be inspected by a professional who can diagnose and fix problems with your system. When you need to replace your radon mitigation fan it is advisable to replace it with one having at least the same flow and static pressure capability.
Why does my radon mitigation fan make a noise?
The fan’s bearings that help to lubricate the motion and reduce the noise start to go bad. This is mainly due to standard wear and tear that happens because the radon mitigation fan runs all the time. Radon mitigation fans are designed for 3” or 4” PVC pipe systems.
How long does it take for radon to return to the air?
The DEP states that the prior high level of radon gas can return within 7 hours if the fan is not functioning. Lowering high radon levels requires technical knowledge and special skills. Radon Protection Systems Inc. is expert in designing and installing mitigation systems to lower and remove high levels of radon gases.
How long is radon mitigation warranty?
We guarantee our workmanship for 2 years. The better fans we have in stock have a manufacturer’s warranty for 5 years. (Most radon mitigation fan manufacturers will only warrant for the full 5 years only if the contractor is a professional.)
How does a muffler help with radon?
EXHAUST MUFFLERS: Companies that supply radon products manufacturer different style air flow mufflers. Some of the mufflers restrict the airflow at higher airflow speeds. This would only affect high airflow systems. Their effectiveness for noise reduction also varies. In general a muffler will not reduce the airflow noise coming from the piping or the fan noise itself. The mufflers will however lower the exhaust noise if they are placed near the exhaust port. The actual noise reduction is moderate but the sound pitch is lowered which makes the noise less offensive. System exhaust noise is usually only bothersome if the exhaust is at the first floor roof and the exhaust pipe is visible from a location that is frequently occupied. A 2nd floor window that looks at a radon exhaust pipe on the garage roof or an exhaust out of a ranch roof that is visible from a rear deck would be good canidates for a muffler. The best muffler noise reduction is with the muffler installed on the end of the exhaust pipe with no chimney cap so that air flow is straight up. We have installed the muffler on the exhaust port on the roof for maximum noise reduction even though it looks a bit out of place.
How much does a 20 watt radon fan save?
A 20 watt radon fan can save $500 in electrical cost over ten years and is considerably quieter. Visit the Radon Fan Performancepage and look up your radon fan wattage. Then check out the fans below. In general the lower the fan wattage the quieter the fan.
How to reduce noise from piping?
INSULATING THE PIPE: Piping that is routed through a space that needs to minimize airflow noise can be insulated for noise reduction. Sliding the next size larger flexible insulated duct over the pipe in the area that needs to have quieter piping can be very effective. Using closed cell foam or thicker walled pipe is less effective.
How to reduce noise from sub-membrane suction system?
The smaller the pipe size drawing air from under the membrane the quieter the air flow noise. To reduce sub-membrane noise, downsize the pipe under the membrane to a 2" pipe which can move up to 50 cfm or a 1.5 inch pipe that can move up to 35 cfm of air.
How to tell if a fan is in the attic?
Place your hand on the fan. Then place you hand on any building component that the piping above or below the fan is attached to. On outside mounted fans feel the siding for vibration next to the first fan bracket above the fan and where the pipe enters the building. If the fan is in the attic feel any framing that the fan is attached to or the pipe rubs up against. If you feel any vibration of building components you can be sure it is being transferred back into the building. Feel the drywall inside the home that is closest to the fan location for vibration.
Can a fan be audible inside?
Fan systems installed outside should not be audible inside unless there is an adjacent window that the occupants occassionally open and they spend time near to. This noise would be from both airflow and the fan. A lower wattage fan would be the best solution. If the noise transfer is through an open second floor window then it is likely to be the piping airflow noise and the exhaust noise. The exhaust piping could be switched to thicker walled PVC piping or even a muffler on the exhaust stack if aesthetics is not a concern.
Can radon be piped through drywall?
ROUTING NEW CONSTRUCTION PIPING: The air moving through a radon pipe has enough noise to be carried through drywall. Try to not route new construction passive radon pipes through walls adjacent to a bedroom, especially the master bedroom. Builders rarely think about this detail. If you can hear air flow noise through the drywall your only partial solution is installing a lower wattage fan in the attic. If it is really bothersome to the owner the system may need to be re-piped up the outside of the home.
How to stop a fan from making a noise?
You could always take various measures to dampen the sound of the fan, either on the fan itself or the walls between. Try wrapping a blanket around the fan, just to see how much it reduces the noise. If that helps enough, find some weather-resistant material to wrap around it, or maybe put it inside a constructed shell that matches your house exterior. It also might work to put some kind of wall-covering on the inside wall next to the fan.
What does it mean when you can hear a blower?
If you can hear it, then it's broken. You probably have a broken fin on the blower blade/impeller or a failed bearing. Get someone to check it out before it completely fails.
Can you reduce the sound of a fan?
It probably won't work to try to reduce the sound by reducing the speed of the fan. It is possible, but kind of in the same way you can convert an SUV into a pickup truck.
Can you plug a radon detector into a timer?
That's a pretty old install, yours may be hard wired, but it's worth checking. If it's just plugged in, you could just plug it into a timer. However, any time the fan isn' t running you'll have the problem of some amount of radon leaking into your house.
