pump testing

[silky]

Is there any consideration to be made if you are drafting from a sea water site vs a fresh water site?

Have never done it, but I would guess there are many things to consider. Besides flushing with fresh water after use, you ought to expect a derated pump capacity due to the higher density/weight of salt water (harder to lift). I know that the Nantucket, MA Fire Dept has done it when needed.
