Important information about Waterway Impellers
Old-style grey smooth nose impellers are no longer available and can not be replaced with #310-4210 black impellers. The new style impellers have a stepped nose and require a wear ring impeller sleeve #319-1370. If you have to replace the older style grey impellers then a complete Waterway Wet End is required and can be found here. It is also recommended to replace the seal assembly at the same time as replacing the impeller to eliminate any issues with performance.
