Submersible for stock watering

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. Since they are not used with pressure tank & therefore aren't protected from cold, they need weep holes about one foot to 1.5 feet below top.
