Installing submersible pumps

They are installed on 1 inch black plastic, or 1 inch galvanized pipe, or 1 inch solid plastic in 21 foot joints. Those on one inch black plastic use safety rope attached to pump. Tape with electrical tape every 5 feet the wire & safety rope. The lower clamps should be taped also. Wires should be crimped with crimping tool and heat shrink tube applied over connection.
