Description
Flat Tank F-Line 7500 litre, Garden Underground KIT includes a 7500 litre 
shallow dig underground tank, inline filter and overflow kit, Hydroforce Series 3 pump and the accessories needed to deliver clean rainwater to a garden tap. 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.

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.
