The sprinkler pump was turning on only for a few seconds and then shutting down and then would restart again for a few seconds... like it could not keep prime. I replaced the check valve and all piping north of it leading to the sprinkler pump. now it turns on and does not shut off but there is still almost no water.
I have tried filling it with a hose from the hose bib.
When I take the house bib off and fill the pump with water, I can see that the water is remaining it is not leaking out.
Was I supposed to fill the suction pipe going into the ground with water before installing the new check valve and piping north of the check valve?
