Rain Barrel Overflow Port

Your rain barrel overflow during an average rain storm?

Install the Aquabarrel Overflow Port and safely direct the overflow away from your home.

No one understands your need for a larger rain barrel overflow port like the folks at Aquabarrel.

We know what it's like to have rain water overflowing off the top of a poorly designed rain barrel.

Install our HUGE multi-part overflow port. You will need to make a hole that is 3.5" to accomodate the new fitting we will send you.

Requires a minimum 4.125" hole in the top of barrel for installation of retaining ring inside the barrel.
