Troubleshooting catchment pump "hiccup"

[rrlovesbi]

I don't know if the water level in the tank would make a difference unless it was uphill from you, or you have a floating intake.

1) You should have a valve in the line coming out of the pump and another where it goes into the pressure tank.  Are both valves open?

2)  Does the pressure tank have enough air in it?

Nope, not uphill - about same level as house pad. Intake near bottom, both valves open. Checked pressure in tank without water in pipes.
