Product information: "BADU® Mat T 1 Topmount"
The valve regulates the flow of water and reverses it according to the chosen settings. Therefore the water flows back through the filter container and starts the backwashing process. These and other functions can be set easily and clearly using the 6-way multiport valve. After backwashing, fresh water must be fed into the system in order to re-establish the original water level. This is best done automatically with the BADU BNR 300 or BADU BNR 400. The 6-way multiport valve can be mounted directly on top of the filter container.
