Rainwater diverter

A rainwater diverter apparatus, comprising:

• a gutter downspout;
• and
• positioned in said downspout, a fluid flow diverter including:
• an outer duct;
• an inner duct positioned within said outer duct, said inner duct having a closed bottom end and defining a reservoir to collect fluid;
• a drainage duct extending into said inner duct and exteriorly of said outer duct;
• said inner duct further having a bypass opening to said outer duct at a height above said drainage duct;
• wherein fluid flowing down said downspout flows into the inner duct and is diverted through the drainage duct, and fluid unable to flow through the drainage duct accumulates in the inner duct to said height, whereupon excess fluid flows through the bypass opening, through the outer duct and out of the bottom of said downspout.

A method for diverting rainwater flowing through a gutter downspout, comprising the steps of:

• providing a fluid flow diverter including:
• an outer duct;
• an inner duct positioned within said outer duct, said inner duct having a closed bottom end and defining a reservoir to collect fluid;
• a drainage duct extending into said inner duct and exteriorly of said outer duct;
• said inner duct further having a bypass opening to said outer duct at a height above said drainage duct;
• and
• positioning said fluid flow diverter in said downspout, wherein fluid flowing down said downspout flows into the inner duct and is diverted through the drainage duct, and fluid unable to flow through the drainage duct accumulates in the inner duct to said height, whereupon excess fluid flows through the bypass opening, through the outer duct and out of the bottom of said downspout.
