Here are two pictures that better explain my situation with the exposed rotor head. One shows the exposed head and the other shows the supply line. You experts toss around all kinds of terms about the supply line which I don't understand so I thought the picture would best explain the situation.I replaced the entire rotor head unit with the same model as the original and did nothing to the supply line. It is lying horizontal in the ground. Only thing I can think to do is cut the supply line and add some extra so I can bury it deeper.Ideas are appreciated.
