Bought a pump today that runs a 2" Npt discharge I'm trying to fill 55 gallon drums to water the garden and on top it's a 2" nps thread. What's the best way to fill these drums. My discharge line just keeps popping out of threads. I'll be filling the drums upright. My discharge line is just flimsy rubber so if I connect to them it going to want to kink so I'll probably need a 90 or 2 90's to fill the drums.
