I bought a home recently and had the flooring redone with tile before moving in. One of the flooring company employees decided that the best place to clean his equipment was the kitchen sink. It filled the garbage disposal and p-trap with sand/grout/cement. I've already replaced the garbage disposal and cleaned the piping under the sink that I can remove. I WILL be seeking damages from the flooring contractor.
My question is, what can be done to clear the sewer line under the concrete slab? It isn't completely clogged, but drains slowly. I've snaked it twice and the problem is still there. Other than ripping up the foundation to get at the plumbing, is there a way to clear the main plumbing line?
I am not sure what direction to head in. Chemical? Mechanical? Rip up the foundation?
Any suggestions would be helpful.
