External pump draw?

[E_rock]

I have been toying around with the idea of adding another small dt to my system in the next few months ones I "finish off" the main dt. The second DT would be one floor straight up in a bedroom where noise is a major concern. Head pressure would be around 10 feet not including a 90 or two. And I am trying to fiqure out a pump to use.

I would rather not try and cramp another mag drive in my sump. Would I just be able to build a shelve just above my sump. And set a inline pump there. And just run a pipe from the intake down two feet to the bottom of my sump. Or can there not be any head pressure in the intake side of the pump?

You'll have to check ratings carefully, because most pumps don't pull water very well. I imagine one of the biggest problems you might run into is trying to prime the pump as our pumps aren't built with port to do so.

Thats a good point. Didnt think of that.
Could I use a check valve on this intake side? I would think that would keep water in the pipe right?

I would not recommend doing that. There really aren't any pumps in this hobby that will happily fight head on the suction side, not to mention the challenge of ensuring it's primed every time it tries to restart.

Yeah, not the best idea there. You CAN mount the pump below the water level, loop OVERSIZED piping up, over the side, and down to the external sitting below the water line, but as DWZM suggests, priming can be a major issue. Few centrifugals self-prime, although there are a handful. There's a reason folks either drill holes in the sump or drop magdrives in there.

makes since I guess if I do these I will just have squeeze another one in somewhere. or split the return between two tanks with a big pump
