OK, never installed a windmill/pump. Should I lower the brass pump attached to 4 lenghts of 2" Galvanized, and then install the plunger and sucker rod (fiberglass), or install the pump with the plunger and attach the sucker rod as I add more lenghts of 2"? The plunger is made to be removed to replace leathers without pulling the pump and pipe. Also do you use a lock washer at the sucker rod connections, or are then not needed..
