Loc-Line Eductor

[The0wn4g3]

I found a thread in the DIY section where someone have the genius idea to use a piece of Loc-Line to create a very cheap and quite effective eductor to increase flow in their tank. Here one that I made:

These simple cuts produced a noticeable increase in water flow from my mag-7. I then looked up a photo of a real eductor and thought to myself, "Hell, I can make that." And here's how it went down:


Go to hobby lobby and find some cheap plastic bottles like this. This is not the actual bottle I used. They sell ones that are about 1/3" the height and 1/2" the width, that's what you want. The nozzles are much wider.

Scrap the bottle and leave the nozzle. Cut the nozzle off just above the threads, leaving a slight ring around the base.

Cut the top of the nozzle off just lower than the edge of the Loc-Line.

Glue the nozzle to the end of the Loc-Line. Here you can see the notches to keep it in place while the superglue dries.

And for real proof, here's a little videos showing the difference:

Grant, I think we're going to have to start calling you MacGyver. Seriously, nice work and thanks for the info. Definitely going to give this a try.

Hahaha. Thanks! I was thinking if there was an interest I could make some for the club.

I sorta failed with the photos though...

Well, they help, but I thought I had a good idea of the bottles you meant. Better with them up, though. Really nice. If you want to make some for people in the club, PM me with what you'd want for them (so we don't break any site rules).

I appears this just concentrates the flow from the pump or reduces the cross sectional area. Also as an unwanted side effect the increased head pressure on the pump may cause wear faster.

good idea in certain applications for sure. something else to think about, thats all.

I'm still doing some tests on it. It's tough to get any concrete results, but I've got quite a few of "eye-balled" results. I'm going to play with the length of the nozzle and such for awhile.
I believe it is producing some extra flow due to Bernoulli's principle, I'm just not sure how much. Got any ideas on how I could find out?
