Stop mosquitoes getting in through your tank overflow outlets with this all-parts-supplied, easy-install Rain Harvesting Tank Overflow Kit High.

Install with ease

Tank Overflow Kits come with outlets, gaskets, mosquito-proof Mozzie Stoppa screens and screws. With everything you need in the box, installation couldn’t be easier. No wonder so many tank manufacturers choose Blue Mountain Co Tank Overflow Kits.

Mosquito-proof your outlets

Our mosquito-proof 955 micron stainless steel mesh protects the quality of your rainwater by keeping mosquitoes and other insects and animals out of your tanks. This also keeps you compliant in areas where mosquito-proofing is required by law.

Installation

Tank Overflow Kit

1. If you do not have an existing tank overflow hole in your tank, use your tank overflow outlet as a template to mark the size of the hole you need to cut in the side of your tank, then cut using a hole saw. Ensure that the bottom of the hole you cut sits lower than the bottom of the tank inlet and/or tank inlet screen.
2. Ensure that the gasket is fitted firmly around the tank overflow fitting, then push it in place inside the tank overflow hole orientated so that the bend faces up.
3. If you have an existing tank overflow hole and doing this means the open end of the bend will sit above the level of the tank inlet and/or tank inlet screen, orient the bend diagonally or trim the top of the overflow first.
4. Hold the overflow outlet as you screw it in place, applying equal force to each screw. We recommend alternating between each screw, screwing on opposite sides, and avoiding fully tightening the screws until the end. Be sure not to overtighten the gasket.
5. To install your Mozzie Stoppa Original, simply press into your tank overflow outlet. DO NOT GLUE IT IN PLACE.
