Are radon mitigation systems required to have a manometer?
First thing’s first, a manometer is a U-shaped tube filled with fluid. All active radon mitigation systems (this just means your radon system has a fan) are required to have a manometer installed so you can see if the radon fan is working.
What is a good radon manometer reading?
between 0.5in-1.75in
Your radon mitigation’s manometer readout should be between 0.5in-1.75in on the Manometer (U shaped- looks like a thermometer). This is NOT the level of Radon in your home. It is simply the amount of vacuum your mitigation system is generating.
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.
What is manometer tube?
A manometer is an instrument that has a small tube in the shape of a U that is filled with liquid to measure pressure or flow. A U-tube manometer is used as an indicator that the fan on the mitigation system is working.
How long does it take for a radon mitigation system to work?
HOW LONG DOES IT TAKE? A typical radon mitigation system is installed within a day, depending on various factors. Occasionally, more complex installations may take 2 or more days.
What level of radon is acceptable?
4 pCi/L
EPA recommends homes be fixed if the radon level is 4 pCi/L (picocurries per liter) or more. Because there is no known safe level of exposure to radon, EPA also recommends that Americans consider fixing their home for radon levels between 2 pCi/L and 4 pCi/L.
How do you know if radon 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.
Why is my radon pipe sweating?
On all radon gas mitigation systems, condensation will form, on and in the PVC pipes. When high humidity is present, you will get condensation on the outside of the PVC pipes. Condensation will form on the inside of the PVC pipe any time the air temperature is lowwer on the outside pipe than the inside.
Can a sump pit be used for radon mitigation?
Drawing and mitigating radon gas from a sump crock is a highly effective solution to successfully mitigating radon from your home. The glaring issue seems to be that most sump crock pits are located in the front corner of the home. This presents a problem of aesthetics and threatens to tarnish your home’s curb appeal.
