Never use Pipeline Industries (PI.) They used Roto-Rooter in Minneapolis/St. Paul metro area as a front company to perform routine drain cleanings. The Roto-Rooter representative would convince the homeowners that costly sewer line repairs and excavation work were needed immediately. That work was fed to PI. Read the complaint against Roto-Rooter in the class-action lawsuit that the law firm of Zimmerman Reed filed in Minneapolis on behalf of more than 100 victims of the PI/Roto-Rooter scam. The basis for it is that Roto-Rooter (who teamed with Pipeline Industries in Minneapolis) fraudulently obtained and pressured homeowners into unnecessary and costly pipeline repair contracts that were fed to PI. Complaint states that Roto-Rooter received "referral fees" for each job given to PI.
