My Sump Return Design - Any forseeable issues? Experts please chime in! (pics)

[CrAzYNeSs]

Hello fellow MFKers,

I recently started a thread about how I wanted to setup the return and am not complete in the designing. I want to see if any of you guys can look over my design plans and let me know if you see any problems.

The area I am most worried about is the amount of flow (GPH) reduction due to the second return line. As you can see I want to plumb it 1" all around until it is in the tank where a 3/4" will be used to mate a Loc-Line fitting ( they don't have 1" versions ).

Please, anyone with experience in this matter, chime in!

The diagram has all the lengths and sizing denoted. Thanks everyone!

The only thing I see is that you might want a "Y" fitting where you have the "T" fitting. This might cause a variation in pressure. At least it did on my setup.

I also have an FX5... where should I place the return for that? Should I just do one return for the sump since I have another FX5?

I need some input for optimum efficiency.

Thanks guys! Always appreciate it.

Wouldn't the valves help to counter that?

I think the "T" creates too much of a bend @ 90 degrees, therefore restricting flow. Not sure but that is what I think Pharaoh meant.

They will to an extent. Strictly speaking from experience here. It does create a bit of a loss in flow.

OP, it does create a loss of flow to the right side output. The Left side will have more flow. You can get "true wyes" from PVCFittings.com

you can eliminate alot of imbalance by splitting the returns equally...

What exactly do you mean? By using a T splitter down the middle?

Thanks!

That looks awesome, I wonder if I could pick one up locally.
