Abstract

See full text

A drainage fitting (10) is described. The drainage fitting (10) comprises a housing (12) adapted to be inserted into a drainage outlet, the housing defining a housing inlet (14) and a housing outlet (16) and a one way valve (18) adapted to be received within the housing (12). The one way valve (18) has a body defining a valve inlet (22), a valve outlet (24) and a valve passageway (26), the passageway (26) providing fluid communication between the housing inlet (14) and the housing outlet (16). The drainage fitting (10) further comprises a fitting insert (28) adapted to be located in the housing inlet (14), the fitting insert (28) defining an insert portion (30) adapted to extend through the valve inlet (22) and into the valve passageway (26). In the presence of a negative pressure differential, air can pass through the valve (18) to relieve the pressure differential, but in the event of a positive pressure differential, the insert portion (30) prevents the one way valve from inverting to relieve the pressure differential.
