Piping System

• Down Pipes: Rainwater flows down from the roof through various types of pipes (PVC, asbestos, cement, cast iron, galvanized iron).

• Elbow/Bend Attachments: Pipes receive water from the rooftop via 90-degree elbows or bends, directing the flow downwards or away from the building.

Filter Installation

• Positioning: The Rainwater Filter is installed at the bottom end of the downwater pipe. It should be connected through a 110mm (4”) elbow and a connecting pipe, maintaining a gap of at least 3” from the floor and 1” from the wall for ease of operation and maintenance.

• Outlet Connection: The filtered water outflow is facilitated by a 90mm or 110mm Tee joint, which can be rotated 360 degrees to position the outlet conveniently. This outlet is then connected to the storage tank.

• Anchoring: The filter needs to be anchored on the wall using pipe clamps or saddles at three locations: the inlet of rainwater, the adapter of the flush valve, and the vertical body of the filter.

Filter Element

• Construction: Made of plastic net and mesh, the filter element effectively filters rainwater. It includes a cap holder for installation inside the filter body, positioning it at the correct height.

• Maintenance: To remove the filter element, pull the cap-holder handle vertically upwards. Ensure the mesh roll is pulled out without crinkling. To reinstall, push the filter element down until the cap-holder sits correctly. The vent hole on the cap-holder should face away from the wall to direct overflow water safely away in case of clogging.
