Old sewer lines
Posted by gary on March 25, 2002 at 00:45:54:
What is the life expectancy of concrete and clay tile sewer lines? I live in Seattle and most of the houses are over 70 years old and some are over 90. I was told by a plumber that it is 50 years. Can you help me become more educated on these old sewer lines?
Thanks,
Gary
