90mm x 90° Overflow Assembly Kit
$30.00 inc. GST
90mm flanged tank overflow kit with built-in mesh screen and high-level 90° bend. Designed to maximise outflow and prevent mosquito entry into poly water tanks.
Description
This 90mm x 90° overflow assembly kit is designed to efficiently manage excess water from poly water tanks. Built for flat-walled tanks, it raises the overflow point slightly to allow an additional ~120mm of water storage before reaching overflow level. The assembly includes a flanged outlet and a mesh screen to help keep insects—especially mosquitoes—out of your tank.
Its unique ripple-geometry comb on the outlet speeds up overflow during high rainfall events, breaking the water surface tension and improving flow capacity. An optional flap screen can be added for additional insect-proofing.
