Disclosed are an outlet filter and an overflow. The disclosure notes that existing outlets allow debris on the roof to enter the outlet which reduces, and may even prevent, water flow through the outlet from the roof. The outlet filter comprises a first strainer and a second strainer. The first strainer comprises a domed grill or grid (15) and is of a size to substantially cover, in use, an outlet (1). The second strainer comprises a series of spaced apart fingers (24) and is spaced outwardly of the first strainer. The outlet filter comprises a base ring adapted to retain the first and second strainers. The base rings comprises further fingers which correspond to extended gaps between fingers of the second strainer when the strainers are mounted on the base ring. |
