Are you building your own rainwater collection system?
Here are some items that should help you in your design:

All-in-One Leaf Filter and First Flush Rainwater Diverter Kit

Raptor fine mesh stainless steel gutter screens

Screened overflow cap
These are available in 3″ or 4″ versions and the attach at the end of the overflow pipe. Allows water to escape, but keeps bugs and small animals out.

Banjo Y-Strainer – 80 mesh, 1″ female NPT
These Y strainers have removable and cleanable stainless mesh filters. Use these when connecting a pump to your rainwater collection tank. Install the strainer before the intake on the pump – this will prevent dirt and debris from damaging the pump internals.
