Anyone local have a extra return pump? I really need one asap because mine is acting up. I can only get it to work on the highest power and that's just to much flow for my returns. Unfortunately I have fish in the sump so I really need a return pump at almost all times.

Unfortunately I have fish in the sump so I really need a return pump at almost all times. I don't have one unfortunately, but putting a ball valve on the return line would allow you to throttle the flow while leaving the oump on high. Lowes/home depot should have them in a size that works. I would think that would be your quickest and cheapest solution in the short term |

That's also what I would do. Run the pump wide open and just adjust flow with a ball valve. Or you could make a diverter valve and pipe to divert some of the pumps flow directly back to the sump allowing only some of the after to go to the display.

From what I've read, the diverter would be the best option, as running a pump full bore into a mostly closed ball valve can blow up a pump in a hurry due to excess back pressure. This is all from reading, as I haven't tried it, but it sounds feasibly true.

What size pump are you running? Gph?

See I thought about the ball valve but my thinking is, if the pumps already messing up how much life does it really have left? Can it take the added pressure of the ball valve holding back.
I'm not sure exactly what the pump was running gph wise since it's a controlled pump and I had it about half way. It's rated up to 9000 L/H

I'm not sure exactly what the pump was running gph wise since it's a controlled pump and I had it about half way. It's rated up to 9000 L/H There is no issue with the back pressure hurting the pump. A valve restriction is no different than if you had a longer run of pipe on the return. Never valve the input though they don't appreciate that  . You're right that the pump (or more likely it's speed controller is on the way out) but having the valve buys you time to find a replacement and can be left in when you get a new pump. It's also possible that on it's highest setting you are essentially bypassing the controller and so the pump could run full bore for a long time, since the pump itself may be fine. |

I've got a backup Mag 12 pump I think, and there might be a mag 18 too.

I think it would be wise to keep some sort of emergency pump on hand anyways.
