A Waterous 2-1/2″ Zinc Screen is a replaceable screen that is installed in the intake of Waterous pumps to prevent debris from entering the pump and causing damage. The screen is made of zinc, which is a sacrificial metal that corrodes more easily than other metals. This corrosion helps to protect the pump from corrosion.
The screen is typically located in the suction line of the pump, just before the impeller. The impeller is the rotating part of the pump that draws water into the pump. The screen helps to prevent large debris from entering the impeller and damaging it.
The screen should be inspected and cleaned regularly to ensure that it is not clogged. If the screen is clogged, it can restrict the flow of water to the pump and reduce its performance.
To replace the screen, simply unscrew the old screen and screw in the new one. Be sure to clean the mounting surface before installing the new screen.
