Hi all,

I am very new to this and I'm trying to understand the overflow/sump
system.
My question is in a non-drilled tank if the overflow looses siphon, will
the
return pump 1) overflow the display tank and 2) will the pump burn out
running dry once the baffled sump space runs out of water?

Thanks for any clarifications. These might be silly questions and if so I
apologize in advance, but I was just trying to figure this out on my own
and
not sure of what safeguards might be there.

Sincerely,

Steve



Hi Steve, if your overflow is properly designed, it will not lose syphon
without being pulled out of the water.
However, the overflow box can sometime be blocked or obstructed which is why
most people try to size their return portion of the sump small enough so
that you will not overflow the main tank.
The only thing that would stop your pump from burning out is if you had a
float switch installed to shut it off in the event your sump got too low.
I'm sure someone else can comment on this further =)
