Gutter systems contain multiple parts and each one plays a specific role in directing water from the roof to the ground. As a professional installer, you understand that a gutter system may be more complicated than it appears to your clients.
In order to set your homeowner clients’ minds at ease, we’ve broken down the basics into simple terms you can share with them. This article will focus on the different downspout elbows available and which should be used in any given situation.
One way to describe downspout elbows to homeowners is by explaining how they connect the main gutter system on the eave of their home to the downspout attached to the wall. The downspout directs the water to a final elbow at its base, guiding the water away from the home at the ground level. Elbows are manufactured in three shapes: rectangular, round and square.
Most of your residential applications will use rectangular elbows and downspouts. While they are available in many sizes, 2” x 3” and 3” x 4” are the most popular options. The elbows are available in either “A” or “B” shape and are configured in various angles:
30-degrees
45-degrees
75-degrees
90-degrees
The 75-degree elbow is the most common choice for most areas of the home, but 90-degree elbows are a good choice if you encounter a tight area that needs a sharper bend.
As you know, whether you use an A- or B-elbow will depend on how you want to connect the gutter to the main house and which direction you want the water to flow at the discharge point. There are numerous ways to direct the water once it leaves the gutter, but let’s consider a standard configuration for the purpose of demonstration.
