My main PVC sewer line (under the slab) had some stubborn stoppage and it was determined that calcium deposits broke apart and piled up, causing the stoppage. The plumber pulled some big pieces (3x6) through the clean out. Wow! He mentioned that the most of the trunk line is lined with this calcium. What chemical or procedure do you recommend? Is there a chemical, i.e. muriatic acid, vinegar, etc. that you recommend; and in what concentration?
