Inquiry (采购产品): Sewer Pipe Cleaning Hi! I was looking on your site. Can you tell me cautions about having you perform a jet through/thorough cleaning on 50-year-old sewer pipe? What are the cautions/precautions on old pipes or can they safely be forcefully cleaned? Thank you. **** Hidden Message ***** Bob Edewaard FL 32601 USA Company: Law Office of C.
