Plumbing to Manifold

I'm a stickler for color PVC...hopefully I can find most of this in Black

Ok...thank you, I have the premise...now I have to apply this configuration to my application. So you strongly feel this is going to get me more flow thru my returns to my display tank? Right now I have very little flow out of my returns even with a valve to my chiller to try and direct more flow to my display tank

Yes, this arrangement will significantly increase return flow rates!

— you are currently supplying your entire manifold with roughly the same amount of water that one of your two return nozzles will be capable of getting after this upgrade!

Your limiting factor will definitely be the display drains, once plumbed as proposed!

You can always paint your plumbing pre-assembly!

 

[Addicted2ACRO's]

That's true...Thank you again for your help. I will post a pic once assembled

I just realized by looking at your diagram I'll have to reverse the plumbing for the chiller...its on the left side of the sump. Shouldn't be a problem

Of course!

I look forward to seeing where you go with it!

Consider adding a few extra outlets to the manifold for use with later equipment, as shown in the diagram! — these reducing tees are great for that!



Additionally, since you’ll have the time to order ahead/aren’t restricted to what the local hardware stores have on the shelf; consider one of these “bullhead” reducing tees for the return plumbing! — this one would go in place of the 1.25” tee with two 1.25-1” reducing bushings!

This is fine, Things can go wherever on the manifold! — as long as the plumbing starts big, then gets smaller where less flow is needed; the possible configurations are effectively limitless!

Cool...Thanks Brother

Hey...I do have another question. I have a Clarisea. Would it be better to supply it with Drain water or plumb it to the spare outlet from the manifold? Another words let the pump supply water to it.

Best bet with most rollers is having your display’s drains go right into it, allowing it to mechanically filter detritus that would otherwise settle in the sump!

Thank you...that's how I currently have it set up

Hello again...I'm drawing out a diagram that would apply to my application and I see some issues with this plan. Especially by adding larger piping that has to be filled.

The Pump is on the right side of the Sump (not in the middle)
The Chiller is on the left side of the Sump.
The height from the Pump to the top of each return is 5 feet ( 10 feet total )
The distance from the pump to the center of the Sump is 3 feet.
The manifold it's self would be 3 feet long.
Then you would have to add a 2-3 feet each for the distance from the manifold to the returns.
Then 2-3 feet to the Chiller from the manifold.
Total distance the water would have to travel is 25 feet.
The pump is only rated at 23 feet of height.
I don't see how I would get more pressure from the pump then I have now...maybe less.
Unless I'm wrong.

Unless I'm wrong.

There’s an easy misconception here!

Your pump is capable of 23ft of water LIFT! — it can pump hundreds of feet horizontally!

— it’s unlikely that you’ll be lifting water vertically more than 6ft above the sump water line, so you’re pump is actually quite alright!

Things like the two return lines going vertically up the back of the tank are combined! — the total vertical water lift, equally between both pipes, is likely under 3ft! (The fluid dynamics involved here dictate that the pump will treat multiple smaller vertical pipes like one big pipe!)


The plumbing can go up and down numerous times before reaching its final destination, too!

— the only important factor for max pump lift/head/well height is: “how far above the pump reservoir’s water line is the highest point in the plumbing?”

 

[Addicted2ACRO's]

Its less than 4 1/2 feet.
Please don't misunderstand me...im not doubting your technical expertise in this matter. It's just an expense and a lot of work I don't want to go through unless it does solve my problem and you sound convinced it will

I totally understand your skepticism! This area of fluid dynamics can be quite complicated, especially at large scales…

Here’s a video I just dug up that does a decent job of explaining what I’m getting at!



It also dives into the nuances between head loss and frictional loss! — the latter is what you’re experiencing currently with all 1” plumbing, and a 3,600gph pump!

 

[UncommonSense]

Here’s another way of looking at frictional loss:

— these are standard flow loss charts for large scale plumbing projects, typically at city water pressure!

— they are measured in pressure loss per-100ft of pipe! (You are using far less length, so you can divide the pressure loss number by ~10! [likely <.1psi loss through 1.5” pump/manifold plumbing])

— your pump will be flowing around 50GPM (observed), but makes <10PSI max… so any significant pressure loss will be much more noticeable than, say, a golf course’s irrigation system!

— note how 1” plumbing stops even being measured at 24gpm of flow, even in much higher pressure applications! (24gpm is less than half of your pump’s flow capability!)

I hope this helps you wrap your head around what I’m getting at! — it certainly took me many years of trial and error!

So after watching the video, it sounds like by running only 1" pipe I'm creating a great deal of friction loss, which hindering the pumps overall performance. I also need to watch the author's other videos to get a complete explanation of fluid dynamics.

Your God sent if this works

I already made a list of the components I will need. I'm going to start ordering them tomorrow

 

[Addicted2ACRO's]

Thanks again...I'll keep you posted

Precisely!

The changes I’ve proposed are all about removing points of restriction to high flow, and making your pump move water as intended!

Your God sent if this works

I think you’ll be plumbing your chiller sump to sump after this just because your two returns will be capable of out flowing your drains if left wide-open on the return valve! — probably right around 3x the total observed pump flow into the manifold!

I already made a list of the components I will need. I'm going to start ordering them tomorrow

Take a few looks at it, I usually find neater ways to put stuff together after giving it a good think! — don’t forget unions for easy assembly/disassembly; put them on the smaller diameter plumbing where it makes sense to save a bit of money on fittings!

Thanks again...I'll keep you posted

Happy to help! — I’ll be looking forward to the results!
