A plumbing drainage fitting (10) is configured to be installed to an outlet of a sanitary ware product such as a wash basin, a sink, a shower or a bath. The plumbing drainage fitting (10) comprises a hollow elongate body (12) comprising a first open end (14), a second open end (166) and an inlet port (18). The inlet port (18) is proximate the first open end (14). A removable one-way valve (22) is insertable and removable via the first open end (14) such that the first open end (14) provides a cleaning access. The second open end (16) provides an outlet port (16), which is connectable to a downstream waste system. The inlet port (18) is provided through the hollow elongate body (12) and opens into an upstream end of the one-way valve (22) such that a substantially L-shaped flow path is defined from the inlet port (14) to the outlet port (16). The one-way valve (22) is operable to permit flow in a direction from the inlet port (18) to the outlet port (16) and is operable to prevent backflow from the outlet port (16) to the inlet port (18).
