The 3P Box Premium can pump water into your storage tank over a conveying distance of 50 m and a height of 6 m*.

Connection and installation
The 3P Box Premium offers connection options for downpipes from 67 mm to 100 mm in the inlet area; the connection to the sewer can be made via a DN110 double socket. To connect the overflow, it is necessary that the standpipe, which represents the discharge into the sewer, is 70 mm above the top edge of the ground so that the 3P Box Premium can be connected here. A standard hose with a quick coupling can be connected via the side coupling, which is then fed into the storage container.

Function
The rainwater flows from the downpipe via the water diverter into the 3P box. There, the water is cleaned of solids and fines by the filter basket with the 3P filterpillows and reaches the lower area where the pump is installed. This then pumps the water through the hose into the storage container. If the amount of incoming rainwater is too large, the water is discharged into the sewage system via the internal bypass. This reliably prevents backflow and overflow.

*This information refers to the use of a 3/4″ hose.

The 3P Box is a holistic solution for rainwater management. With the 3P Box installed directly on the downpipe, you collect the rainwater exactly where it falls, clean it of fine particles, leaves and solids and can then convey it to where you can best ensure its storage on the property using a pump already integrated in this compact product. You are independent of the type of storage tank. It can be underground, above ground, made of plastic, concrete, fiberglass or any other practical material and does not have to be installed in the same location as the downpipe.

This offers significant advantages, particularly in the area of retrofitting existing buildings. Storage tanks no longer have to be installed close to the house, but can be installed wherever the local conditions allow.

If your storage tank is full or you do not want/are unable to pump water in winter, the water is discharged directly into the sewer via the internal bypass. In this case, the installed pre-filter functions as a water switch and you can put your 3P Box into or out of operation with just one turn.

Removing the pump in winter is just as easy. Simply disconnect the screw connection and remove the pump through the cover (see illustration).
