Our farm has an awesome old cast iron hand pump to access water in an underground cistern. To improve efficiency, I’d like to attach a 5/8" hose to the pump, to carry water to a barrel closer to where animal chores are done. I don’t mind using the hand pump for now, but the outlet is not threaded, but is a 3" cast iron flare on a 2.5" pipe at the outlet.
I’m thinking that a rubber coupler could attach by going over the flare, but I don’t know where to source such a thing.
Any ideas? Thanks,
