What do you guys think of this return plumbing+ manifold idea

Hey Guys

I have a Jebao DC12000. I want to redo my plumbing. I have too many 90 in the return. I have 2 return outputs and they just hang onto the tank.

I want to increase the diameter from 3/4 return to maybe 1 inch or 1.5 inch and just have 1 return output.

While at the same time, I want to make a manifold. I found this manifold idea from Bay Area Reefs. It sounds like a great idea, but I want to hear your opinions before I start getting stuff.

Do you guys think its a good idea? Do you think that 90 before the manifold is harsh? Even the 90 after the manifold?


My specs are in my sig. 6 ft long tank to add.

Thanks guys!

The 12000 should at least run with 1.5" pipe, maybe even 2" if you really want all the flow.

I think a simple line of tees is a more logical manifold setup than that... Unless you just have a spaghetti mess of vinyl lines on barb fittings coming out of it at least. Also i wouldn't make a manifold inline with the return, rather tee it off the main line with valves to close both legs entirely.

Thanks for the input!

Yea I think I'm going to Tee it off. The reason why I thought about doing it this way was to relieve any head pressure on the pump.

Can you link me with a manifold/return design you think has the least amount of head pressure on the pump?




Also For a 6 foot tank... do you think I can just have 1 return? The output on the 12000 is 1.5. I might keep it 1.5 all the way. I have 1 inch drains currently. I probably can't change the drains either.

Thanks!
 
I have a very similar manifold on my new tank. However, I used a dedicated pump for the manifold. I would consider doing that because you may find you're going to lose too much flow trying to feed the tank and the manifold. Not only do you have head loss (the force of gravity) working against that pump, but you also have friction loss with all of those fittings.
 
Btw, I ran my DCT 1200's with 1.5" pvc, (3/4" manifold lines) but as mentioned 2" wouldn't hurt.

As long as you are mixing the water well with powerheads then a single return basically anywhere should suffice to keep processing the tank water in the sump. The siphon can probably keep up with the pump, depends on the head loss in the pump and the head in the siphon... A 4' head on the siphon should allow for a max of 2357 gph of drainage, which lines up pretty well with 4' of head on the dc12000. But it doesn't leave much room for adjustment.

If your gap is longer than 4 feet though you will be better off.
