How to Convert a Submersible Pond Pump to an External Pond Pump

Place the base of the submergible water pump face down on the ground next to the pond.

Place an end of one of one of the plastic hoses over the outflow hole in the base. Secure the end to the base with strips of duct tape. Apply a line of bonding glue around the end of the hose where it meets the base. Let the glue set overnight.

Apply a line of silicone sealant paste around the end of the hose where it meets the base. Let the paste set for six hours, then reapply another line of paste to the end of the hose. Let six hours pass before removing the duct tape.

Turn the base right-side up. Screw the intake column into the middle of the base. Place an end of a plastic hose over the intake hole on the column. Secure the end to the column with strips of duct tape. Apply a line of bonding glue around the end of the hose where it meets the column. Let the glue set overnight.

Apply a line of silicone sealant paste around the end of the hose where it meets the column. Let the paste set for six hours, then reapply another line. Let six hours pass before removing the duct tape.

Insert the end of the power cord attached to the column into an extension cord. Plug the end of the extension cord into an outlet. Place the ends of the hoses into the water. Turn the pump on to begin aerating the water in the pond.
