Double down?

[boondocker]

Anyone ever try and run 2 surflo pumps on a 3/4" main line? I was thinking of a "Y" in the mainline and a pump on each side. Obviously going in series wont do anything to inhance vacuum but i would like to hear from someone who has tried it or opinions. Thanks in advance.

You would have to run a bypass to both to keep them wet, big difference when they have liquid to move. They are designed to move liquid. Vacuum is created in doing so.
