Are Those Rainhead Holes Important?
The holes you see on a rainhead are there to allow any excess rainwater (in a heavy downpour or if a downpipe becomes blocked) to overflow out of the front of the rainhead rather than backflow into the building.
The holes themselves can be any shape or combination of sizes as long as the total opening is equivalent to that of the size of the downpipe.
The bottom of the holes should sit approximately 25mm below the sole of the box gutter outlet. Would you like to update your guttering and rainheads? Give Roofrite a call to obtain a quote.
