Alright, so I have the power supply, a reset button (doesn't matter if NO or NC), a DPDT relay, a floater level switch and a pump.

I need to wire it all up so when the level goes down the floater will activate the pump, but it can only be turned off once I press the reset button. I am pretty newbie to this an haven't been able to come up with something after 4 days thinking about it. If I need anything else to make it work let me know.

Hope someone can help me, thanks.

We can try words. If not I'll make a diagram.
Use the normally open on the float switch to turn on the pump.
Wire the n/o of the relay across the float switch.
Put the reset switch between the float switch and the relay coil.
So.. if the float switch is on the pump runs. At the same time the float switch will "pick" the relay if the reset switch is not pressed.
The relay contacts across the float switch will keep both the pump and the relay on until the reset is pushed.

 

Yes, I had just finally figure this out when I saw the reply. Better late than never.

Thanks for the response though. Much appreciated.
