Underground splice to 14 TWU?
I'm reusing an old well pump and repurposing as a river pump. The pipe needs to go 200' across some land (buried 2') and then connect to a pressure tank in the garage for irrigation only.
The current wire on the pump is 3 wires 14TWU. One red, one black, one white. Where I cutoff the old connection, it's connected to what looks like 12/3 with a ground as well.
What is the yellow wire on the pump? And do I need 12/3 UF to splice to this? I only have 12/2 UF so if I have a long enough piece could I cut a 2nd length and just label one of the wires red.

Isn't submersible well wire the same as UF in terms of strength, ie you can bury UF so can't you bury TWU?
Can I use 2x14/2 lengths of UF to make 3 wires (with a spare not in use) and splice that to the 14/3 TWU?
Not sure what I should label yellow wire as, white presumably?

Having a yellow wire on a well pump usually means the pump needs to be connected to a starting relay box and not directly connected to a power source.
The yellow is normally the run winding but you need to check what your specific pump requires.
What type of pump is this?... make and model ?
Nnormally only a submersible pump is connected with a relay box.

Yeah I have the control box. Goulds submersible pump. But the control box will be in the garage and is 300' from river to garage and I have 200' of old pipe and submersible wire. I need to splice in 100' of probably 14/3 to connect then maybe put the individual submersible wires in conduit.
Or just get a new section of 300' 14/3.

It's not in yet but they're is 200' of existing 14/3 rubbing the pump and has been for 25 years. It was then connected to 12/3 for about 100'.
Assuming the same would work.
Nothing's connected yet so can't measure but the pump needs 240v and 5.6A.
