FUNCTIONING of the MwStop® check valve
As soon as water runs through the pipe in flow direction, the membrane of the MwStop® backflow valve is subject to increased pressure. This pushes the diaphragm upwards so that water can flow freely below the membrane. The rising water pressure triggers a controlled surge flushing, which in its turn ensures the regular removal of present sediments. And what is more, another functionality of the MwStop® backwater check valve, is that the tight seal reliably prevents unpleasant odors in the pipe network.
As soon as water runs through the pipe in opposite flow direction, the membrane of the MwStop® sewer check valve fills up, and as a result prevents the water against back flow effectively. The backwater height varies depending on the MwStop® model (with a maximum of 8,000mm).
