I'm trying to replace a 30 year old 3 wire submersible pump. The existing wire line from the pump to the well head only has a red/black/yellow cable. All of the pumps I've seen now come with the green ground wire. What is the best way to replace the pump? I.e. New pump (obviously) and new wire? Can I use the existing wire and convert to a 2 wire using the yellow for the green? Can I just not use the green at all?
The other thing that I'm not sure of is the two black wires from a two wire pump. The existing pressure switch has two black leads and two whites leads, this is fine because of the control box. But if I go with a two wire system, I have to assume it doesn't matter where the two black leads go from the pump.
Any help would be appreciated.
Thanks
