Plumber redoing horizontal main sewer line in the basemet, the old was causing back flow at least once a year because apperently the pich was backward from the main drain to the back wall of the house. Now I'm adding extra sink to already existing toilet, shower, sink and loundry in the basement. Plumber wants to install in wall air vents that will be about 4,5 feet off the floor. Should I be consern of these kind air vents causig any problems in the future s.a. smell and etc.?
