What angle are your downspout elbows? Until relatively recently, 90° elbows did not exist, the elbow and downspout machines did not have a setting for 90°. rather the standard elbow was 75°, even though commonly referred to as 90°.
There was a reason for that, a 75° downspout elbow generally accomplished what you would want from a 90° and there were some concerns with a 90° elbow.
Once concern is that the sharper angle would cause the elbows to clog up more easily with debris. A second concern is that the extra bend in the elbow would weaken the aluminum.
Recently, although still uncommon, 90° elbows have begun make their way to the market, initially with copper elbows. Copper is a stronger more durable metal, so concerns of the curve causing the metal to weaken were lessened.
Historically, when aluminum elbows were marketed as 90°, it was referring to 75° elbows, however we have recently seen actual 90° aluminum elbows available on for sale, typically via special order.
