Mounting CL pump above waterlevel?

[reverendmaynard]

Hey all,

Is there any problem with putting the CL pump above the waterlevel in the tank, assuming that all the nozzels are low enough to not be exposed during power off of the return pump?

I'm thinking of mounting mine right at, or slightly above the water level in my tank.

How are you planning to prime it? I think once you get it going - in theory you should have no problem....

But IMO, you may have cavitation issues withthe pump drawing head instead of creating head pressure... It's been a few years since fluid dynamics.
