Not content with the backwards start issues that plague the Sicce PSK-2500 design, Warner Marine has started to test a new pinwheel design that they hope will eliminate the issue. The initial design is based on the factory Sicce impeller and works on the principle that the “factory impeller turns in the correct direction because it can’t start in the other direction. It features 3 curved paddles that move the water inside the volute. These paddles are arrayed in 3 arcs. The paddles ‘can’t’ start in the wrong direction because of water pressure.” The new design will prevent “backwards starts” as it does in the original factory design. You wont be able to get your hands on these for a least a couple of months but we have learned that the air:water ratio should be the same. If you’re an owner of a K2 protein skimmer you won’t have to pay a cent for this upgrade, something that is becoming rare in the world we live in.
