Ok so I got everything running tonight, and it seems that on my open system, the left side (facing from the back of the tank as in pic) is barely pushing any water out..while the right one is pumping away, Its all 1" PVC , I am running a Mag 12 and no matter how much I turn it up ..same thing...I am assuming its not getting enough pressure in the PVC T..any suggestions..i would hate to replumb.....its not the system plumbed with the SCWD...its the open system up top.

There may be an ait bubble in your system. The same thing happend to me...

hmm....how did u find it and fix it?

 

[Buzz_Hog]

water takes the path of least resistance...

WHich is out the end of the tube....

I'd say to replumb it and have the return go to an T intersection in the center of the two outlets...

WIth the way it is now.... the first one in essence acts as a venturi.... as the water passes by the hole out the side of the tube, it creates suction.... You need to create pressure within the tubing.

I agree with Buzz... either T it up, or put a ball valve on the end return pipe to create some resistance which will make the water exit out the T fitting as well.
You probably won't need to put a ball valve on the T, just the elbow... you can piece in whatever distance you need to make up once you add the valve in.
That's about all else I can suggest.

Not to beat a dead horse, but a 't' is needed to even up the flow.

 

[3Twenty5]

I am told that putting a ball valve between will also work?

 

[Reefer Addict]

Yeah, that should work too...
/me beats himself in the head with a fish.
I guess I was concentrating on you not having to modify what you had already finished. You can just add it in between the T and the elbow.
Ball valve's a pain to get adjusted correctly as compared to a gate valve, but it should be adequate for what you're trying to do.

The easier solution would be to put a 3/4'' or maybe even a 1/2'' to restrict the end and force more out the previous tube. That how I got around the problem and its way easier and cheaper than replumbing or adding valves or ''T''s.

Another T would reduce the flow altogether. You just want to back the end pressure a little and keep the same gph.

Just my opinion and what has wrked for me.

Do you mean run a 1/2 reducer with locline in my 3/4" bulkhead on the side which has too much pressure?

 

[Doug1]

that would work

UPDATE:

I added a ball valve between the 2 returns...works perfect...my MAG12 was pumping too much flow anyways, so It didn't hurt to restrict the flow. I still have to throttle it back a little, but now I get a nice even flow between both returns
