I have a plumber coming out tomorrow (Wed) to give me an estimate on mechanicall removing roots from my sewer line. I don't have time to get multiple quotes and would like to give him the green light to proceed if the price is reasonable, but I don't know what a reasonable price is. My sewer line is about 150 feet long and probably pretty overgrown. Has anyone had this done? If so, what did you pay and how long was your sewer line? P.S. I've looked into chemicals like copper sulfide and rootX, but it appears that you are better of removing roots with mechanical auger first, then keeping things in check with annual chemical treatments. Also, a year ago one plumber quoted me $3000 for installation of a new sewer line, but I would like to postpone that.
