F-Line Flat Tank 5000 litre, Complete System underground KIT includes a 5,000 litre underground tank, 91 litre header tank, inline filter and overflow kit, Hydroforce Series 3 pressure sensitive pump, 25m of 25mm Green & Black HDE pipe, Rain Director and the accessories needed to deliver clean rainwater for home and garden use. Some standard external pipework and connectors will be needed but are not included in the kit as the location of the system will determine the amount of pipework required.

Why buy this system?

  • Our Rainwater Harvesting systems are based on the highest quality, rotationally moulded, one piece tanks, installed without the need for concrete, thereby minimising installation costs and supported by our long term 25 year tank guarantee.
  • Minimum installation depth
  • Easy and quick to install
  • Small excavation pit and little earth excavation preserves your garden
  • Ideal for installation in new or existing properties
  • Can be installed in ground water up to tank shoulder
  • Pre-fitted filter, Calmed inlet, and overflow siphon
  • Automatic mains switch over with the Rain Director®

The Rain Director® rainwater management system includes a header tank, a pump and a programmable control valve unit that directs the flow of rainwater to washing machines, toilets, the garden and other uses. A header tank in the roof space is controlled by electronic level sensors. These sensors drive the valves through the programmable control panel. The result is a constant head or pressure of water to the toilet, washing machine or tap.

The Rain Director® is specifically designed so that rainwater can be used safely and economically in the home. The system features:

  • Fail-safe valve controls with mains backup
  • Fail-safe header tank controls
  • Water quality is improved through cycling of header tank water
  • Saves energy and prolongs pump life
  • Assures water supply during a power cut
  • Automatic and user-controlled functions
  • No in-home pump noise

Easy to install

The F-line flat tank can be installed into much higher water tables than a standard round tank. If you don't know what your water table will be like in the winter, you're safer to install a flat tank. The F-Line tanks are flat and the installation depth is 60% less than other rainwater tanks. The excavation can be up to 70% less, meaning little earth excavation, easy handling and less cost for you! The small excavation pit is easily filled in and your garden will look just like it did before.

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.
