External HDPE Rainwater Pipe included. It is important to identify a source of a water supply. Untreated rainwater is not for human consumption and so water companies are recommending (and in some cases requiring) that Black and Green HDPE pipe is used for piping rainwater from the tank to the point of use - eg. garden tap. The point of use should be clearly labelled to show that rain water is the source. We include 25mm black and green hdpe pipe and labels with this kit with the option to buy further rolls of pipe.

More about the Rain Director®

The WRAS approved Rain Director® is an intelligent domestic rainwater storage and distribution system. There are two components - a Smart loft header tank and a 12v Valve Control Panel to direct the water flow.

The Smart Header Tank is controlled by electronic level sensors, valves and control panel. The advantages over normal rainwater pumping systems are:

• Variable rainwater level in the smart header tank (all water is used before it’s refilled) eliminates pump cycling and reduces power consumption.
• The header tank only refills once it’s completely empty (while normal rainwater systems make the pump start every time any amount of water is used) so wear on the pump and electricity usage are both reduced.
• The tank provides a constant flow of rainwater under gravity at any time, including during power cuts and of course is built with fail-safe controls.

The Rain Director 12v Valve Control Panel controls the water delivery - whether rainwater or mains water. The Rain Director®’s Control Panel provides a simple set of buttons to set the operation. For example, the Rain Director’s auto-flush function detects when the occupant is away from home (for example, for holidays) and empties header tank to avoid rainwater there becoming discoloured (dark coloured water and stained toilet bowl, to be avoided).

The Graf Platin tank is the latest tank from the rainwater harvesting experts Graf in Germany. of its kind in the world to be manufactured by injection compression moulding. This technique provides the tank with unbeatable stability and ensures that each component is produced with the highest accuracy. Graf have invested €20m in their factory near Freiburg for the Carat and Platin range, introduced in early 2007.
