I have an onga model 445 pump wont work on a generator

if the pump is delivering to the hose tap then it is working
there has to be a problem in the plumbing and control arrangement to the house taps for there to be no pressure at the house
possible tap turned off to the house circuit
Is the pump big enough to supply constant pressure /flow to more than one tap
what sort of pressure control unit is there on the pump
what distances and head heights are involved from the water level in the tank to the house taps
Is there water flow from the house taps but not at pressure
the pump should be able to maintain at least 35psi with at least 4 taps running

Release AIR lock. Air has got trapped in the pump hence it cannot create necessary level of suction. The way normally you do this by filling the water path of the pump with water and get the air released.

More information would be helpful. Did it freeze? Why is it hard to reset, is it because you did not waite a few minuts befoe resetting.

either water lock or motor burnt out ,

What is the model of the pump? What type of control does it have - pressure switch, electronic controller or what?

a number of possibilities like insufficient pressure in the bell or pressure leak 'or pump motor dying
but i'd be looking at a warranty claim

The pump is equipped with a pressure switch.It is a rectangular thing on the discharge side of the pump. If you open its cover, you will see 2 springs with turning bolt on top. The larger spring controls the operating pressure (pressure where you want the pump to stop), and the other one is for the pressure differential (the difference between the pressure you want to stop and the pressure you want to make the pump run again). Usually, the springs are graduated. just turn the adjusting screws to the desired operating pressure and desired differential. For example you want to stop your pump at 40 psi and run it again at 30 psi. Adjust the larger spring to 40 and the smaller one to 10.
