Help me understand plumbing.....

[ecreef]

So help me understand this new tank that I have. He had it closed loop and I got a pm explaining how it was setup...

"
Hey, I had the 6 2" pipes on the back of the tank going to the hammerhead pumps, 3 to each pump and then from the pump they went back up to the top of the tank sort of like a manifold with about 12 outlets. then the 4 bulkheads closest to the top of the tank on the back where the overflows for the sump and then the returns from the sump were the 2 hole closest to the center on the back. Hope that helps, If not, I am sure there are tons of people on the forum that would be able to stop by and help, or give some extra ideas. Good luck, and I can't wait to see the tank up and running again.
"

So, since this has no overflows, am I to think the sump could overflow without power or the sort. I thought closed loop was a closed system. It this the best way to set up this 225 tank? I do have picture if needed. Just trying to figure out how I should go about this. The ideal way to to not have back flow issues in power issue times. (which are not often)

A picture would help but if you're going to a sump, that part is not a closed loop. A closed is one where water stays in the piping from the time it exits until it returns.
The tank could drain down to lowest hole you have for the sump in event of a power loss or leak. The sump portion of the system will not work the way you describe it.

I will work on the pictures....I thought that too about the cloased loop/ So if I wanted a true closed loop system how would you set it up with what was listed.....

The 6 outlets going to the hammerhead pumps (3 go to each pump) are part of a closed loop. The remaining 4 outlets, which he said are near the top, drain to the sump. And I guess there are 2 returns from the sump. When the power goes out it will drain to the lowest bulkhead that is connected to the sump (either the intended drain or through the intended return, whicever is lower).

By the description it has three circuits:

1. The tank>sump>tank (or drain>sump>return

2. one closed loop which will be 3 tank 2" lines to one hammerhead pump and from there back to the tank but over the top

3 second closed loop will be the remining 3 tank 2" lines to the second hammerhead pump and then back to the tank over the top

Some notes::
4 bulkheads closest to the top of the tank on the back where the overflows, in other words the drains to the sump

2 holes closest to the center on the back were for the return lines comming from the return pump in the sump.

So in summary this tank has:
Three 2" inlet pipes for each of the hammerhead pumps. (with two inch dia one for each pump shall be more than enough the other four can be plugged. (using a bulkhead and a threaded plug)
Six pipes from each hammerhead to the tank overtop as closed loop returns. I would use one 1-1'2" line from each pump and manifold them over the top for three outlets each rather than siz each)
Four drains to the sump. If each drain is 1-1/2" or larger I think no more than 2 are required)
Two returns from the sump that is OK.

Just for kicks here are the pics.....sorry for the quality......you haev to look to see the top holes. So, is the sumper even needed really?

or, could/should I add like a mini overflow setup just to limit how much water can fall in....like a 3' deep over flow from the top sealed...if that makes sense.

Does this mean that you're not selling it?

 

[ecreef]

no, I still think I am to be honest. I am just trying to rest asure that this may be more work then I care for...I will let you know ethir way of course.....

 

[Caleb Kruse]

How did Brandon have the overflows working when he had the tank?

 

[ecreef]

No overflow bow built in I think.

2 hammerheads will definitely do the job, that's going to have some serious flow if set up properly.
