Anyone know a good plumber? Our sewer is backing up again, even though it was just rotter rooted last saturday and our connection to the city has been redone. Pretty sure it is a clog somewhere between our dishwasher and the connection in the basement bathroom because it only backs up in the basement sink when we run the dishwasher. The plumber who came out last time was kind of rude and wasn't listening to us. Any suggestions would be appreciated!
