Abstract

Plumbing apparatus for incorporation in a waste pipe system comprises a tubular body 12 having an inlet 14 for connection to an upstream waste pipe 16 and an outlet 18 for connection to a downstream waste pipe 20. A one-way water valve 22 is provided in the body and is arranged to permit flow from the inlet to the outlet and to prevent flow from the outlet to the inlet. An air valve 24 is mounted on an upper portion of the body and is arranged to permit flow of air into the body and to restrict flow of air out of the body. In the event of negative pressure in the downstream waste pipe system, the air valve opens to allow air to be drawn into the system. In the event of positive pressure in the downstream waste pipe system, the one-way water valve closes.
