Product Description

800L Wall Tank - 800 litre Rainwater Water Butt

The best slimline 800 litre water tank for slim and sleek storage of a larger volume a rainwater, the 800 litre Rainwater Tank from 3P Technik are the way to go for 'medium scale' Rainwater Saving or Harvesting, and specified by professionals where bulk storage of rainwater and a compact footprint are required.

A step-up from the water butt sizes, the Wall Tank enters into the world of the true rainwater storage 'tank' and is perfect for a vast range of uses - be they in the garden or for the home. Their footprint is the key, with a small base of just 80cm x 60cm they can fit just about anywhere around the outside of a modern dwelling space. Especially ideal for storing rainwater that could be supplied to, for example; utility rooms, wash-down areas, workshops (for water-reliant tools), toilet spaces, or maybe even under a garage or carport for cleaning the car and watering the garden. Not forgetting that rainwater is softer than main-supplied water and is ideally used around the house in hard-water sensitive appliances or for cleaning glass. The keen gardener with a poly-tunnel could also find this an ideal size for feeding irrigation systems.

Our slim 800 litre water butt is available in four attractive matt colours - Granite, Sandstone  and Black.

When placed against a wall, space must be provided to allow the tank to deflect once filled without touching the wall. 

For this 800 lite rainwater tank, we recommend connecting your downpipe with the Filter Collector. This filter is everything you need for collecting water from your downpipe and filter any debris before transferring the water into the tank and is offered at a special price when bought with the Wall tank. Please just select a colour to match your downpipe to include the filter collector (1 sent with each wall tank, if no filter collector is required select "none").

This unit is also the base unit for our Wall Tank Rainwater systems, fully thought-out and assembled sets to serve a variety of purposes. If you have need of a complete and integrated pumped-system then take a look at ouWall Tank Systems page.
