What comes with this kit?

Graf Optimax Pro filter included as standard
In response to customer demand, we have included the Graf’s Optimax Pro filter which fits neatly inside the turret of the Carat tank. With its integrated overflow siphon and inlet calming device, we no longer need to cut holes in the turret other than those provided by Graf in the moulding.

The Optimax Pro Filter is self cleaning - water arriving across the filter mesh pushes excess debris and leaves to the overflow. The optional extra hose connector permits you to connect a hose and wash it through more thoroughly from time to time. 

If you are referring to the Graf catalogue or brochure, this kit from RainWater Harvesting is the equivalent to the Graf Eco Plus Package; our kit includes items 1) the Tank 2) the dome or “turret” and 3) Filter package 3. In place of the Graf pump package we provide the high quality, popular and more reliable EnviroF 1100 watt submersible pump, and a inline filter to take the cleanest water first. 

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.

Upgrade this kit - With a 'Rain Manager' fully automated water management system in place of the pump. For more information please click here

Options (please phone for availability and price)

• Self-cleaning hose connection kit for Optimax filter
• Vehicle load-bearing dome 
• Turret (dome) extension for burying the tank deeper

The product code has the suffix D for "domestic" (so you can use the system to provide water for flushing toilets and washing clothes) but we can recommend the same set-up for garden use, washing the car etc.
