A fitting (10) for a sanitary unit outlet (5) has a tubular housing (12) having an inlet (14) and an outlet (16), a grid (18) associated with the housing inlet (14) and a one-way valve (20) associated with the housing outlet (16). The housing (12), grid (18) and one-way valve (20) are configured so as to be removable from the sanitary unit outlet (5) as a single entity to permit, for example, the one-way valve (20) to be replaced. |
