Inquiry (采购产品): Mark II radon system Hello, I recently moved into a house in Ann Arbor, MI that has your Mark II Radon system installed. I have never lived in an area that required these systems so I am unfamiliar with how they work. Everything seems to be working ok, but I would like to know how the radon interfaces with our sump pump, because the pump may need to be replaced in the near future. The previous owner did not leave any documentation about the radon system. If possible, I would very much appreciate if someone could send me any documentation that could help me out (owners manual, etc.). Information can either be sent electronically or by mail (see contact info). Thank you very much. **** Hidden Message ***** Thomas Ferris 2725 Hampshire Rd Ann Arbor, MI 48104 USA Company: University of Michigan Phone: 319-594-3217 E-mail: ferrist@umich.edu **** Hidden Message ***** ferrist@umich.edu
