I am purchasing a home that I think has a pb service line. I'm looking to confirm that its actually pb and that I have a problem. All of the distro lines are copper so no worries there. I scraped the pipe at the meter (it was covered in years of dirt) and it looked gray as well. Its approx. a 60ft straight shot to the water meter. I'm guessing this will cost me a grand to do myself (w/copper).
