Easy to install with no tools required, Tank Guardian fits securely to an existing tank screen to make cleaning the tank inlet area easy. With a 0.04" stainless steel screen, Tank Guardian stops leaves, debris and insects from passing through to the tank screen, ensuring it stays clean. This reduces water contamination and ensures that the optimum amount of water is collected. Tank Guardian is simply placed on top of an existing tank screen and then easily removed to clean the tank inlet area.
