Pivotable downspout extension system

A pivotable downspout extension system, comprising:

• an adapter coupleable to a fixed-position downspout, the adapter comprising:
• a water channel extending at an oblique angle in relation to the fixed-position downspout, and
• a first arm and a second arm positioned beneath the water channel;
• an extension arm pivotably coupled to the first arm and second arm of the adapter, the extension arm comprising:
• a housing comprising an aperture configured to receive the first and second arm of the adapter,
• at least one counterweight within the housing,
• a channel extending from the housing and formed from a first side and a second side coupled together via a living hinge, and
• a pocket in the housing for receiving water at a base of the channel;
• wherein when water does not exceed a predetermined threshold in the pocket, the extension arm remains substantially vertical and substantially parallel to the fixed-position downspout;
• and
• when water in the pocket exceeds the predetermined threshold, the extension arm pivots on the adapter, allowing the water to drain from the channel of the extension arm.
