Technical Examples

A system for removing odorous air from a toilet bowl into a sewer line includes a toilet seat defining a plurality of air inlets spaced apart along a bottom side and an air outlet at a rear side with an internal channel connecting the air inlets and outlet. The system includes an air pump suitable for mounting to a rear of the toilet for connection to the toilet seat with tubing. A pressure sensor on the seat actuates the pump to draw air through the inlets to the pump upon sensing the pressure of a user thereon. Additional tubing extends from the pump through the toilet wax ring for exhausting the air into a sewer line. A check valve on the additional tubing prevents return of sewer gas into the system.
