Looks like you have some fabrication skills, nicely done. For a DUI, err, DIY sorry project, it looks very nice. If it works similar to an eductor, even better. If I'm not mistaken, there's alot of flow testing and tweaking an eductor goes through before it makes it to production, and for good reason. The eductors multiply the stream going through them by creating an area of low pressure at the inner nozzle, and the water is sucked in, multiplying the amount of water. Yours may work a little, hopefully works well. Great workmanship!
