WARNING! This is a picture of a radon mitigation system that was installed by another company. We were called out to this house to replace the original radon fan that is no longer working. This is an example of a radon mitigation system that was installed wrong. We couldn’t replace the radon fan because the previous company violated electrical codes. Preforming work on this system would be dangerous and a potential liability for us. Unfortunately we see a lot of radon mitigation work like this.
