National Poly’s leaf strainers dramatically improve your water quality by preventing leaves and debris from entering your tank. Strainers are available in 300mm or 420mm diameters and are designed with a generous depth to reduce the risk of overflow. All leaf strainers that we provide you with are made using food contact approved (AS/NZS 4020:2005) stainless steel mesh to keep your rainwater safe and pure. Did you know that you can receive on the spot fines if your rainwater tank isn’t mosquito proof? Rest assured that all of our strainers are made with an aperture that surpasses state regulations for mosquito prevention.
