The JoJo Tank Screen Filter is a high-performance, low-maintenance component designed to fit directly into the top manhole of your water tank. As the primary defense against organic contamination, it effectively strains out leaves, twigs, and larger debris before they can enter the tank, preventing the buildup of sludge and protecting your pumps and downstream filtration systems.
Key Performance Features
- High-Grade Stainless Steel Mesh: Features a fine-aperture mesh that captures even small organic particles while allowing for a high flow rate during heavy South African thunderstorms.
- Integrated Insect Barrier: The mesh is fine enough to prevent mosquitoes and other pests from entering the tank to breed, ensuring your stored water remains hygienic.
- UV-Stabilized Housing: The outer ring is manufactured from the same robust, UV-protected polyethylene as JoJo tanks, ensuring it won't crack or degrade under direct sunlight.
- Easy-Clean Design: Engineered for tool-free removal, allowing you to quickly lift the screen, discard collected debris, and rinse it clean in seconds.
Ideal Applications
- Rainwater Harvesting Systems: An absolute necessity for any tank connected to a roof gutter system to prevent gutters' debris from rotting inside the tank.
- Pre-Filtration for Pumps: By removing solids at the source, the screen filter significantly extends the life of your pressure pump and prevents "clogged" irrigation nozzles.
- Gravity-Fed Systems: Ensures that water drawn from the bottom tap is as clear as possible by keeping the "sediment layer" to an absolute minimum.
Product Benefits
- Prevents Water Stagnation: By keeping organic matter out, the screen filter reduces the nutrient load in the water, which helps prevent foul odors and bacterial growth.
- Fits Standard JoJo Manholes: Specifically designed to drop into the 480mm manhole opening found on most vertical and slimline JoJo tanks.
- Low-Profile Aesthetic: Sits flush with the top of the tank, maintaining the clean lines of your water storage setup.
Pro Tip: For the best results, check your screen filter after the first heavy rain of the season and then once a month thereafter. If you have overhanging trees, you may need to clear it more frequently to ensure water doesn't "overshoot" the filter and spill over the sides of the tank due to a leaf-clogged mesh.
