ABSTRACT:
A recreational vehicle or boat toilet includes a bowl with a water ingress line to the bowl, and a flush mechanism for emptying the bowl after water from the ingress line has entered the bowl. The recreational vehicle or boat toilet also includes a ventilation apparatus including an odor vent line communicating with the water ingress line and with an exit line leading to the external environment. Additionally, a water overflow line communicates with the water ingress line, with the odor vent line and with the exit line. A vacuum apparatus communicates with the exit line such that the odor passes from the odor vent line, through the exit line and to the external environment, and such that overflow water passes through the water overflow line, through the exit line into the external environment.
