Ballvalve
General Engineering Contractor
Sewer gas -septic smell invading a bathroom on an intermittent basis. Started a year ago, stopped, back again part time.
Shower, 2 sinks and a toilet in this bathroom. Traps are full. Toilet replaced about 3 years ago. Where to start? poor seal at wax ring, with some intermittent "back" pressure from the city mains? Under slab leak? - Desert climate, slab on grade.
Does the average plumber have a sniffer or some system to zone in on the locale without tearing into stuff?
