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. The pics below show a 1500 tank as an example to illustrate the work required, obviously 3000 - 7500 litre tanks have different dimensions but they are still 'shallow dig'.

What about In-Tank Filtration?

The F-Line Tank comes with the option of an In Tank Filtration pack. The set has all the components needed to filter the rainwater as it enters your tank and drain any surplus to your overflow.

The fine filter filters dirt particles, before they reach the tank. The filter cartridge can simply be taken out for maintenance and can be easily cleaned.

All the parts are pre-mounted ready for connection. To buy this option see the drop down menus below or call 01733 405111.
