If you’ve been experiencing a loud radon system, it could be a result of several different factors. These include vibration, condensation, ice, and normal wear and tear. If you’re not sure what’s causing the noise, check the FAQ below.
Vibration
If you’re wondering why your radon system is so noisy, you might be in need of some maintenance. While most radon systems are hard-wired, you can modify them to operate on a timer. There are some ways to do maintenance yourself, and one of them is to check the air velocity of the system every month.
One of the most common reasons your radon system is making such a loud noise is due to the fact that it’s not installed properly. If you’ve had it installed improperly, there may be water accumulating in the pipes. To fix this problem, make sure your vent pipes are installed without bends, and that their pitch is towards the ground.
Condensation
Radon systems are notoriously loud, but there are some things you can do to minimize the noise. One of the easiest ways to reduce noise is by installing smaller pipes. You should aim for a maximum air movement of 34 CFM through a three-inch pipe. This will reduce back pressure and noise from the system.
Noise is caused by three main sources. Your radon mitigation system can reduce these sources by customizing it to fit your house. If the noise is a problem, it’s important to troubleshoot the system to find out what’s causing it. One of the most common sources of noise is turbulence in the air. This causes a whistle-like sound and is caused by the wear and tear of components in your system.
Ice
One common reason radon systems make such a racket is the freezing of the vent pipes. This happens when the temperature drops below freezing. This is more likely to happen in northern climates such as the United States and Canada. It is particularly common on metal downspout vent pipes.
To make sure your system runs quietly, you need to check the air velocity. The ideal air velocity is 700 fpm. Over-straining a system’s fan will cause it to make loud noises and reduce its efficiency. It’s also possible to purchase smaller pipes that move less air.
Normal wear and tear
Radon is a naturally occurring gas that can accumulate in your home. It is odorless and invisible and is created when radioactive materials break down in the ground. It can be a danger to your health, as radon can damage the lining of your lung. It can be particularly dangerous if you live in an area where radon levels are higher than average.
A radon system has several components. One of these is the vent pipe. When the system is operating, it must keep the pipe free of debris. A radon vent pipe contains two sections. The pipes are connected to each other by u-tubes. One pipe draws the liquid up from the soil while the other runs up through the side of the home. The difference between these two columns is the amount of actual suction in the pipe. If one column is full of red liquid, and the other is empty, the fan is off and needs service.
Incorrect installation
The improper installation of a radon system can lead to a number of problems. One common problem is that the pipe for the vent is not installed properly. For instance, the pipe for the exhaust of a radon system must be installed at a 45-degree angle above the eaves or roof line of the house. In this case, the vent pipe was improperly placed and allowed hornets to make a nest.
The wrong installation of a radon system can increase radon levels in the home. The correct installation of a radon mitigation system can minimize radon exposure and give you peace of mind. If you aren’t sure how to fix it yourself, consult with a professional. Then, determine the root cause of the problem.
