It's self priming to 5' when the impeller is wet, 4' when it's dry, Steve.

To my knowledge, the Jabsco centrifugal macerator IS NOT self priming and is
suppose to be installed below the liquid level of the tank.. I think I
remember reading this in the installation instructions for one I had
purchase in error.

For me, this it the reason I had to go to a Sealand diaphram pump (no way to
get the pump lower than the tank bottom).

Perhaps Peggy Hall can shed some light on this.
