Does sump pump drain line need to be below frost line?
Yes, the sump pump drain line should ideally be installed below the frost line to prevent freezing during winter months. If the drain line is above the frost line, the water inside can freeze, leading to blockages and potential damage to the system. Proper insulation and placement below the frost line help ensure the sump pump operates effectively year-round.
