The odor is in the sinks overflow system. Pour a drain cleaner or bleach into the small overflow hole in the sink to get rid of the mold, bacteria, etc. which has made its home in there.: new mobile home 8 months old made by skyline homes. sewer gas in bathroom sink very bad smell. skyline homes and there plumbers checked it out they said all trap and vents ok and no leaks, can any one help?
