Check for Tree Roots Angie's List (steel) Oct 07, 2010Clogged sewer lines caused by tree roots is a common problem in older neighborhoods, says David Specht, president of The Waterworks, a 10-time Super Service Award winner. "Most homes built before the 1960s used vitreous clay for their main sewer lines," Specht says. "Roots can penetrate weak areas of the clay and grow large enough to cause the pipe to break or collapse." (pipe) Common Causes of Flange Leaks and their Solutions (steel) Jun 22, 2017A related problem is temperature variation around the flange circumference (e.g., cooling on top due to rain, or cool liquid at the bottom and hot gas at the top). Where this is a problem, sheet metal shields can be installed to protect against rain or snow impingement that could cause thermal gradients across the flange and cause leakage.
