Graf Platin Flat Tank Packages With Divertron Pumps (pedestrian loading)

Designed for minimum installation depth, the Graf Flat tank package is the practical option to provide a sophisticated underground rainwater harvesting system targeted specifically for garden use. Both the 1500 litre and the 3000 litre tanks can be installed in a hole less than 1m deep, making them a viable option for retro-fit installation. Requiring less digging, they are quicker and cheaper to install into many landscaping schemes. In addition to the tank, the package includes a mini telescopic tank shaft and lid (with options for either pedestrian or vehicle loading), a removable basket filter (with overflow siphon) and a pump package 2 (with floating intake).

Our pump packages use intelligent demand-switched pumps, so they will automatically start as soon as the tap is opened and will shut off when it is closed. The output from the pump can be connected directly to our ‘Plumb Your Garden Kits’ to provide a number of standpipes around the garden to give a pressurised source of soft rainwater and to supply simple tap-based irrigation systems. Alternatively with the addition of a mains water top-up kit the output can be connected directly to a manifold and used for a larger underground irrigation system.
