You can use the U-tube manometer to see if your system is operational. Examine the liquid in the tube. If it is the same on both sides, it means there is no pressure in the pipe. This indicates that there is no suction from the fan (far left image), and the radon mitigation device is not operational.
If the fluid in one corner of the tube is higher than the other, this means air is being drawn through the fan into the pipe. The radon mitigation device is operating properly.
Radon gas is an odorless, colorless gas that can enter your home through cracks in the foundation or flooring and seep into different parts of the house. It is found in almost all homes with a basement or a patio attached to them. When exposed to sunlight, radon gas becomes radioactive and disintegrates over time. The only known human carcinogen emitted by natural sources is radon. Studies have shown that it is responsible for approximately 20% of all cancer deaths due to its effects on the lungs.
The best way to prevent exposure to radon is to fix any cracks or holes in the foundation or flooring and check the radon level in your home regularly. If the test results are high, contact a licensed contractor who can help reduce the radiation levels inside your home. You may be able to get money back from your insurance company if you can prove that the radon reduction measures you took reduced your coverage amount by more than 10%.
The radon system produces two types of noise: air movement and vibration. When too much air is pumped through the pipe, excessive noise and back pressure are produced. A 3" pipe should move no more than 34 CFM before the system becomes excessively loud and loses efficiency, according to the highest standards. The vibration from the pump will cause wear on other parts of the system, such as valves and heaters.
If you live in an area that could potentially have high levels of radon, we recommend that you hire a contractor to install a radon mitigation system. Only a licensed professional can ensure that your system is installed properly and meets local requirements. You need someone who knows how to avoid disrupting your home while still providing adequate ventilation for reducing risk of exposure to radon.
In addition to being noisy, radon systems use electricity to operate their pumps. If you have an electric bill above what's normal for your household operations, there may be another reason why it's so high. Check with your utility company to make sure you're not experiencing any power outages or voltage fluctuations. If everything else is OK but you're still getting a high bill, ask your contractor about this possibility when they do their final inspection before they sign off on their work.
High radon levels can also lead to increased energy usage if you have to run the heater or air conditioner more often to compensate for the reduced airflow caused by the radon system.
Check to see if your radiators have chilly patches at the top but are warm at the bottom to discover if your heating system needs to be bled. If this is the case, you must bleed them to let the trapped air to leave and the hot water to circulate freely once again. This can be done by turning off the power to the heater for a few hours first, then opening up the access panel and removing the radiator cap. Turn the unit over so the cold side is down when you reconnect it to the power source.
After performing this service, be sure to replace the cap after closing up the panel. This will help prevent future problems with your radiator system.
If you don't know how to perform this service, we recommend having a professional do it for you. It isn't difficult but it does require some knowledge of both gas and electric systems. You could potentially damage your heating system if you try to do this yourself. They only cost about $75-$100 and it can save you money in the long run by preventing major repairs.
Overall, keeping an eye on your radiators will help you identify any issues early on. If one starts to leak or doesn't work properly, get it fixed immediately before it gets worse. This will help ensure you don't have any major problems with your heating system.
