ET 20-SC incorporates a self cleaning feature whereby a fixed strainer screen removes contaminants before reaching the valve orifice. The only maintenance required is to open the ball valve periodically. The full flow would then be redirected from a 90˚ position to a straight through direction which cleans the filter screen of collected contaminants with a short blast. All other components such as coil, timer and cord are same as ET-20 drain.
