Ventilate your tank safely

This tank outlet screen facilitates tank ventilation to preserve your water quality without letting mosquitoes in.

The Mozzie-Stoppa Advanced protects your rainwater by utilising a removable 955 micron stainless steel screen that keeps mosquitoes and other pests from getting into your tank through the overflow.

Tank ventilation is important for the health of your rainwater, and so is avoiding contamination by mosquitoes and other pests. Importantly, it still lets water flow out so your tank outlets can continue to fulfil their main purpose, uninterrupted.

  • Installation
    1. Select an installation point for your Mozzie Stoppa™ Advanced. As it will require regular maintenance, we recommend installing in a position that allows for easy access and cleaning. In most cases, the best position will be directly into the overflow outlet of your tank with the handle pointing upwards. Also ensure that the installation position allows the handle to be removed fully.

    2. If necessary, measure and remove a section of pipe leaving a gap between your overflow outlet and overflow pipe. For a Mozzie Stoppa™ Advanced 90mm, we recommend removing approximately 22mm. For a Mozzie Stoppa™ Advanced 100mm, we recommend removing approximately 24mm. And for the 150mm version, we recommend removing approximately 28mm. Once the pipes are cut, ensure the edges are clean and smooth.

      NOTE: If adaptors are being used to adjust the pipe diameter, the recommended length for cutting out pipe will vary – measure with the adptors in place.

    3. Prior to gluing, remove the Mozzie Stoppa Advanced mesh cartridge, so that there is no chance of glue getting on the mesh.

    4. Use solvent weld glue to install the Mozzie Stoppa™ Advanced into the gap you made in Step 2, between your overflow outlet and overflow pipe.

    5. Once the solvent weld glue has dried, re-install your mesh cartridge into the Mozzie Stoppa™ Advanced body to secure your system and prevent pests from entering your tank.

  • Maintenance

    Your Mozzie Stoppa™ Advanced is designed to make maintenance and cleaning easy. Remove the mesh cartridge by pulling the handle by pulling it directly out of the body. Replace the mesh cartridge immediately after cleaning by firmly inserting it back into the corresponding slot in the body so it continues to form a barrier against mosquitoes, frogs and pests. Periodically inspect the mesh cartridge o-ring to ensure that the system seal is still performing optimally.

  • Product FAQs

    Where do I install my Mozzie Stoppa?

    You can use your Mozzie Stoppa to protect any pipe opening and create a mosquito- and pest-proof barrier. Mozzie Stoppas are typically installed to rainwater tank overflow outlet pipework to help mosquito-proof your tank. To learn more about installation, visit the Support page for your chosen product.

    My tank is overflowing at the inlet rather than the outlet. What should I do?

    1. Check that your tank screen is free from debris, ie. leaves, sediment
      Your tank outlet may be restricted by a blocked Mozzie Stoppa or another obstruction.
    2. Check your overflow outlet for the presence of an obstruction and remove.
    3. Alternately, the level of your tank overflow may sit above the base of your tank inlet.
    4. Check that the outlet pipe is equal to or greater than the combind capacity of the pipe feeding your tank inlet
    5. If a Mozzie Stoppa is installed, remove, inspect and clean if necessary before reinstalling it at the outlet.

    If your inlet/overflow issue persists, remove your tank screen and check for floating debris on the water surface. Floating debris such as sworf from the tank installation process’ may be blocking the Mozzie Stoppa during overflow and drifting away from the overflow when overflow has stopped.
