Gutter outlets fitted in the conventional way cause rubbish to build up in roof gutters. Gutters start to rust because they are not able to drain out efficiently or dry out completely after rain. This creates a breeding habitat for disease carrying mosquitoes.
In most instances gutter outlets are fitted by cutting a hole in the gutter, pushing an outlet through from the top side of the gutter, fixing it in place with a few rivets or screws, and then applying a silicone sealant around the top side of the gutter outlet within the gutter itself. This creates a barrier up to 4mm high for debris to jump and obstructs water flow .
