Recently conducted a radon test where the mitigation system was in place but not functioning. Client still wanted a test. Manometer showed no suction and the fan was not operational. The 2 day test came out good at 0.8 pCi/l. The realtor asks how can that be?
Answer: The system was installed 2 owners ago with no information on why the system was installed. It may be the owner installed it for preventative reasons. Another possibility is that an initial test was done during the winter months with a possible outcome of testing just over 4.0 pCi/l warranting a system. Weather could have played a factor, no one knows.
So what do you do in this scenario?
Answer: You explain this is good news and while low readings are not cause for concern at this time, in winter months levels can test higher. Therefore, the radon mitigation system should be repaired to working order and running so low levels are consistent throughout the year. Further explain that you will include photos and comments of the non working system so the repair can be negotiated in the real estate transaction.
