How do I Clean Calcium/Lime Deposits in Main Line

[jigsaw]

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?

Thanks for all your help,

He suggested hydro jetting but was not sure if this 1500psi machine would take care of the problem.

No it will not ;
you need a big jetter 3000 to 4000 psi possibly with a chain knocker on it !

I am not even sure that the diagnosis is correct. Was it inspected with a camera? When I have found "stuff' like that it was usually tile grout that was dumped down the drain without a lot of water to flush it through.

He used the camera and I saw it. He also pulled out multiple pieces. I am about to perform my own version of chemistry on the extracted pieces.

No matter whether calcium/lime or tile grout the hydro jetter with chain knocker
will remove it !

And yes i agree with you more likely tile grout

Would the choice to use a chain knocker be affected by the type of pipe? Cast iron, PVC, ABS, clay?

Of course if it was clay, Jigsaw probably would have also mentioned roots.
