Works: under normal working state of backwash filter belong to "internal pressure type", through the pressure of tap water by screen wall penetration to the outer wall, sediment, rust and other impurity particles trapped in the tube, open the flush valve intercept impurities were washed away by mesh, if you meet the water quality is poorer, consumers for a long time don't wash, blocked the also don't have to worry about. Through the backwash switch to make the piston run to the bottom, change the direction of the water flow into "external pressure" embedded in the surface of the filter element can not be flushed off the impurities, by the reverse running water washed away.
