View Full Version : Closed Loop Flow problem

02/01/2007, 10:49 AM
I have a CL with a mag 12 running it. I am running 3/4'" pvc outlet pipes down to 6 1/2" locline outlets and a 1" pvc intake. I am not getting the flow i want out of the CL. I think I have to many outlets...

What is anyone elses opinion?

Does locline make a stopper or cap to stop the flow out of some of my outlets?

im kinda in the same boat. I have a T4 running 1" pipe to 3/4" locline. I also have less than desireable flow out of the three outlets. I am planning on capping one of the outlets (at the BH) and installing a tunze 6045 to replace it.

From my experience with Mag12's on a closed loop. I had very low flow with 4 outs, changed to 2 and it was higher. Mags dont do well with head pressure, so your 3/4 inch return pipe is restricting flow also. I used 1 inch and flow was ok. they recommend 1.5 inch, but I had no room for that. I would try reducing the outputs to 2 and see what happens. Loc-line also has valves in which you can regulate the flow for each return.

Also, how many T's, 90's, etc.. do you have on it?

You amy want to look into an Oceans Motions to alternate flow between output.

Thanks for the info... I'll try capping down to 2-3 outlets and see if that will help.
