- 1). Turn the pump off.
- 2). Remove the fill plug from the top of the pump housing with an adjustable wrench. On most pumps, the fill plug is a square-headed bolt mounted in the top center of the housing directly above the suction line.
- 3). Loosen and remove the small vent plug. This is usually located either directly above the suction line or beside the fill plug on the top of the pump housing.
- 4). Fill the pump housing with water. Pour slowly. The water will flow into and fill the suction line, forcing air back through the pump housing as it fills.
- 5). Replace and tighten the vent plug when the pump housing is full.
- 6). Replace the fill plug but do not tighten it.
- 7). Turn the pump on. Allow the pump to run until water begins to escape around the edges of the fill plug.
- 8). Turn the pump off. Remove the fill plug and fill the pump housing with water again if necessary.
- 9). Replace and tighten the fill plug.
