4" Overflow Elbow
The 4" Tank Overflow Elbow with Mozzie Stoppa Screen (PN TATO123) is a robust, purpose-designed overflow fitting for rainwater harvesting tanks and cisterns. It includes a built-in stainless steel insect screen—the Mozzie Stoppa—which blocks mosquitoes, frogs, and debris from entering your tank through the overflow line.
This 90° elbow fits standard 4" pipe or outlet fittings, directing excess water away from the tank base while protecting your system from contamination. Built from durable, UV-resistant materials, it’s ideal for both above-ground and below-ground installations.
