I have a lot of sewer problems which I thought were primarily caused by my big oak trees and roots getting into the sewer line. I may still have to replace my sewer line eventually, but Paul not only opened up the sewer line for me, but also made the suggestion that a toilet with a larger trap would be beneficial. Apparently my toilet was made in 1988 and the trap is very small which cause it to clog up. Why has no one told me this before? Thank you, Paul - and thanks for your fair pricing!
