Thanks for all the reply's it is nice to have the community for more than just a buy/sell board.
I will try the throttling back.

I've seen this happen with these pumps when people don't plumb large enough pipes and bulkheads. Untamed is also correct regarding cavitation which is essentially the same thing, a good cleaning could fix things.
If not it could also be the seal on the pump, anywhere you notice salt creep could be a potential leak.

and then work my way up from there. I really hope it is not a joint above the true union. I dreamt of Rubber Maids and total tank cleanouts last night.
** If I take apart the impeller do I need a new seal kit?
