Ok, this is helping my paranoia. Thanks very much for all the great info, guys.
Any suggestions where to get an appropriate amp meter? How expensive are they? I don't think my little $10 0.5amp multimeter is going to cut it... if I do a measurement on the pump draw.. :rolleyes: [img]smile.gif[/img]
PS. Cavitation. DUH. I can't beleive that didn't occur to me. And I work for a oil and gas, water and wastewater pipeline SCADA vendor!!

Frightening. Well, no, I'm not at work now, so I'm allowed to be dumb. :D Well, the good news is that the pump is not cavitating...
