Hi Bob, Thanks for the reply and I apologize for my lock of knowledge.
There was water flow with the old pump which must of still let water
through when it was off somehow when the new one does not.


That sounds very much as if you have got the inlet and outlet pipe
connections the wrong way around. There is a one way valve in the
pump on both hot and cold.
