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.
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.
Tank Overflows provide additional security for your tank’s connections, and allow you to effectively manage overflowing water. Tank Overflows also allow you to increase your water tank’s storage, enabling you more ability to plan for volume.
We recommend regularly cleaning your Mozzie Stoppa to prevent the mosquito-proof screen from becoming clogged or blocked with sediments and debris.
To clean, remove your Mozzie Stoppa Original from your tank overflow outlet and hose or otherwise clean the mosquito-proof screen. Replace the Mozzie Stoppa Original immediately after cleaning by pressing it back into your tank overflow outlet.
Your Mozzie Stoppa Easy-Clean is designed to make maintenance and cleaning easy. To clean, simply unlatch the hinged screen and hose or brush it off. Replace the screen immediately after cleaning by pressing it down to firmly relatch it in place so it continues to form a barrier against mosquitoes, frogs and other pests.
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.
Check your overflow outlet for the presence of an obstruction and remove.
Alternately, the level of your tank overflow may sit above the base of your tank inlet.
Check that the outlet pipe is equal to or greater than the combind capacity of the pipe feeding your tank inlet
If a Mozzie Stoppa is installed, remove, inspect and clean if necessary before reinstalling it at the outlet or replacing with a Mozzie Stoppa Easy-Clean.
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.
High or extra high tank overflows offer a simple and effective way to increase your tank’s storage capacity.
Whichever tank overflow product you choose to use, your overflow needs to sit below the base of your tank inlet screen. The advantage of the high level overflow is that it raises the maximum water level within the tank.
The diameter of the overflow must be equal to or larger than the diameter of the inlet pipe.
Each tank overflow kit comes with a tank overflow outlet, mosquito-proof Mozzie Stoppa screen, a gasket and screws so you have everything you neeed for installation. The size of the components included in your kit will depend upon the product you order and are listed on each individual product page. (For product-specific information, visit the product page for your chosen tank overflow kit via the links above.)
The bend on your high level tank overflow should face up towards the top of your tank in order to increase your tank’s storage volume and overflow height.
Yes. We recommend installing your high level overflow with the bend facing directly upwards, however, it can also be installed on an angle to adjust the upper level. This may be necessary to ensure the overflow level stays below the base of your tank inlet and/or tank inlet screen.
No. The Mozzie Stoppa Original (TATO05) is not self-cleaning, so it requires periodic removal and cleaning. The socket and spigot feature ribbing that provides a secure, non-glue fit. (For full installation instructions, see the Support page for your chosen tank overflow kit.)
