Did you remember to re-open the seacock? :)

Great suggestions on the raw water question...thanks to all!

Went through the entire system today and found a leak in the pump.  After 
replacing the gasket, have been unable to get any water through the system..

I drained all the water out when I inspected the heat exchanger.  Is there 
some trick in priming the pump so it draws water, or if it doesn't, do I 
assume the pump is not operating? I had some intermittent water flow before 
but none now.  Pulled the hose at the intake side of the heat exchanger and 
it was dry so no water is getting that far.

Thanks,
Jim   #453
