2 pumps on 1 bulkhead? Ok or no?

[Delphinus]

Sounds good, thanks. It seems to me "it could probably work" also means "it could probably not work" and if there's a chance I have to drill out a new bulkhead anyhow, I might as well do it now when the tank is empty rather than down the road. I suppose that leaves more options open anyhow. Worst case scenario I end up not needing the bulkhead (ie., move to an insump skimmer) but then I can just cap it off, or use it for water changes or something.

Darts can be fed with 1 1/2 bulkheads on closed loops easily because of the head pressure available, drawing from a sump however is slightly different, the higher the sump level and the greater the surface area will help in making this work fine.

I would go for it.

the surface area really has nothing to do with the pressure of the water at the suction, it is all hight. that is my concern as most sumps are not that tall and we don't run them full so the suction head is going to be small. now if he had a 24" tall sump and ran it at 23" I would say most likely it would work, but that is unlikely.

thats what I would do. makes for a nicer install also as you can have the pumps in different areas with out them being tied togeather.
