2x EDUCTORS & NO MORE POWERHEADS!! - Page 3

ivgonmad,
Can you post pictures of each part? I just looked online at Lowes using the item numbers in the list, and only 2 of them show up. I am wanting to go get the parts, but I do not have a clear picture in my head of what I need.

I guess I will go to Lowes and look around and see if I can find something using the descriptions...
If you could post pics for each item that would be great!

Thanks,
David

Ok, I went to Lowes today and bought all of the parts. Here are pictures of the parts for reference

From left to right:
barb, bushing spigot, coupling and female adapter.

Reducer Coupling, front and back of package

All of the item #'s he gave matched up exactly to the items at my Lowes. Having the manufacturer of each part helped a lot.

The barb was found in the section for lawn irrigation systems.

The reducer coupling was found in the section for sink drains.

The rest was in the pvc aisle. White pieces regular pvc, black pieces ABS.

I plan to start construction tonight and will take more pictures. Hope this helps.

Thanks for the extra info as well marino420td. The pictures help alot. Just as a side note Lowes in Australia is a clothes shop

Hence my asking for the pictures.

Chris.

One question. Did you cut down the bushing spigot before gluing it into the coupler? In your pictures and drawings, it looks like the lip of the bushing is right against the coupling. The bushing would have to be cut shorter to accomplish this.

I don't see this anywhere in the instructions and I'm a little confused. Thanks.

Thanks for posting those pics!!! Lots of people asking for them!!

"I don't see this anywhere in the instructions and I'm a little confused"

Sorry dude, forgot that step, hehe I cut it with a hack saw... Then I glued that to the other piece!

Sorry, I think thats the only step I forgot

That's great. I did use one on my tank a while ago, but I used the instructions from Geoff's site (The Mantled Monster).

ivgonmad, kudos to u for bringing this to our attention and nice DIY project like I said b4.

marino420td · #58 04/23/2007, 10:29 PM

Here is a pictorial of the entire construction process.

I will not leave it like that in my tank. But I didn't have to proper pvc parts to install it correctly.

DrBDC · #59 04/23/2007, 10:38 PM

Well how's the flow from it?

marino420td · #60 04/23/2007, 11:07 PM

I was wondering when someone would ask. I really can't tell yet. My CL that it is hooked to has 4 other outlets so most of the flow goes through them. I need to make another to hook up them plug the rest of the outlets to test them. Ran out of time tonight.

ivgonmad · #61 04/24/2007, 12:42 AM

Good job, came out nicely!

You can screw in the reducer coupling all the way in too, so it doesn't show the white thread!

What kind of pump are you using and how much water and height can it handle?

4 Eductors is a lot of flow.

marino420td · #62 04/24/2007, 08:17 AM

I can't get the reducer coupling all the way in. The threads are too tight and I can't grip it.

My CL pump is a sequence Dart. I'm thinking of just having two eductors and closing off the other outlets.

Saltcreep1 · #63 04/24/2007, 11:55 AM

Hmmm... is it just me or is there something fishy with the physics involved here.

I don't think an Eductor can increase flow.......it may change the flow....but it is not adding any energy.

They may be very good at mixing fluids ....but I can't see how it can increase your GPH of water.

DrBDC · #64 04/24/2007, 12:03 PM

It actually wouldn't increase overall kinetic energy. Energy in=energy out subtract loss due to heat, resistence, etc. But, it would decrease volume and width at the pump outlet with an increase in velocity and lower volume. Then in exchange it draws from the sides which might make more "movement" or rather the surrounding area water moves which makes better flow patterns in the water. ie. decrease dead spots on the sides of the eductors. I know, I'm a little rusty on physics but you get the general idea.

ivgonmad · #65 04/24/2007, 02:17 PM

I does not increase the effectiveness of the pump or the amount of GPH pumped, it increases water flow by re-circulating water that is already in the tank using the power of the water being pumped into the eductor.

It uses the energy from the jet coming from the pump to drag in to the eductor up to 5x the amount of water that is actually being pumped.

For example... If you are pumping 500gph... Your eductor will displace up to 2000gph from within the tank + 500gph that are coming from the pump.

Saltcreep1 · #66 04/24/2007, 02:29 PM

Ok...I can buy that.

It is a way of directing flow more efficiently.

I would still like to see some kind of real numbers before I take down my B.S. flag.

Try some silicone lubricant or/and some pliers to get it in all the way.

I think 2 eductor should be fine, If your tank is very long , you might want to see if your pump can handle a 3rd or all 4 eductors.

Dude.... I'm just helping those who want to be helped, this thing works, you can see in the video that its working...

If you are not convinced go and make one for yourself ($5 aint gonna make your poor), buy a flow meter, and attach it to the eductor somehow and show us your results.

I don't need to prove anything to you or anyone, I am sharing this here because I thought others could benefit form my DIY version of a commercially available product that I thought needed some tweaking to work better for us, if you don't want to try it its ok with me.

Just don't go saying that this is bull if you don't even know or understand how it works.

Pbrown3701 · #69 04/24/2007, 03:02 PM

I use an eductor (purchased type) and i can vouch that it makes a HUGE difference in in tank flow compared to w/o the eductor. It easily doubled the flow in my tank by doing nothing more than screwing it on...

Oh jeeez...here we go......

Take it easy man. I'm not saying it doesn't work.

I am asking for some hard numbers to see how well it works.

Why? Because when you say:

"For example... If you are pumping 500gph... Your eductor will displace up to 2000gph from within the tank + 500gph that are coming from the pump."

That makes it sound like you have increased to waterflow in your tank from 500gph to 2500 gph just by adding this device.
Wouldn't that raise you BS flag?

A 500gph pump without an eductor is also moving much more the its 500 gph. The the water from the pump is transfering it's energy as it collides with tank water.

So.....

Before I run out to the harware store, I would like to know how much of an increase we are talking about.
If it's only a 1% increase it's not worth it to me.....
If it's a 50% increase I'll be the first one in line at Home Depot.

See my post above. I "easily" doubled the water flow in my tank from adding an eductor....go line up

ivgonmad, its people like you that try and HELP others, that make this place what it is..... and keeps me coming back to learn more about this hobby.

chris wright · #74 04/24/2007, 07:37 PM

Well im certainly going to give it a go. If at worst it doubles the flow thats good enough for me.

Ill be using a variation of the parts used, I looked at the link posted and when I went to the hardware, I couldnt find the exact parts, but theres one variation. The end piece reduces as part of the adaptor. Sort of like a batten holder light fitting, only not as exaggerated.

Ill post results as soon as I can make everthing up. Thanks again guys for the info and supporint pics.

If it works right, LMK, always looking to upgrade the current version.
