It allows the connection of a hose to the pump within the tank to provide recycled rainwater for irrigating lawns/gardens, car washing and other outdoor water needs. Moulded in one piece from Medium Density Polyethylene (MDPE), this seamless non-corrosive tank with a strong body, an adjustable turret and a calmed inlet can be installed very easily. The system complies with EN 16941-1:2018 and Part G of Building Regulations in U.K.
It comes equipped with a ‘Backup in a Box’ rainwater distribution system. This allows connection of the tank to a direct plumbing system to supply appliances such as toilets, washing machines and the garden. The ‘Back up in a Box’ unit supplies the household with rainwater from the storage tank. Once rainwater has been exhausted, the unit replenishes the storage tank with mains water.
Note: The two-tank systems require a suitable connection between the provided tanks (not supplied) which will depend on the system orientation.
