Plumbing backed up pipe to the second floor after plumber out last month to clear lin
We have an old three story home and had clog last month and plumber cleared line and some roots. The plumbing again backed up all the way to the second floor and flooded the first floor and the basement days ago, un benonst to us. Now the second plumber came out again and cleared the line all the way to second floor and said he does not know what the first plumber did but the line was backed all the way up.
Is the first plumber responsible for the damage done to our property by his incomplete job?
