The bad news is this.... These systems were installed by a certified radon mitigator. My first comment upon seeing the photo was "What was this guy thinking?" "He should know better than that." Then a thought of how this guy would give all mitigators a bad name. You can not say enough about experience. The mitigator is fairly new to the field and has not acquired the knowledge yet to install systems properly. You should check the experience on any company/contractor that works at your home. Problem with the above system is that it has condensation traps and will collect large sums of water in the ducting. Causing mold, mildew and premature wear on the blower motor.
