The invention discloses a pipeline shunt pedestal pan which relates to sanitary ware and comprises a water tank, a drainage valve, a water guide passageway, a spraying water channel, a spraying hole, a washing water ring, a blow-off pipeline and a toilet bowl, as well as a slope structure which is formed in the way that the tail section of the water guide passageway is raised to form a slope; the outlet of the slope structure is the outlet of the water guide passageway, and the outlet of the slope structure, namely the outlet of the water guide passageway, is positioned at the highest level; and a pipe neck-shaped shunt water retaining part is arranged at the inlet of the spraying water channel. The pipeline shunt pedestal pan has the benefits that water is fully filled in the front section of the water guide passageway for a long time due to the slope structure, and when the drainage valve is opened, the time for fully filling the water guide passageway is saved, the water quantity of the washing water ring is adequate due to the quantitative shunt of water flow, the washing force is strong and the effect is good, and the washing is conducted simultaneously with draining, so that formation of siphoning action is promoted to a greater extent, non-functionalization water quantity at prior period of siphoning action is reduced, effective water consumption is improved, the water consumption can be reduced totally, and a role of saving water can be played.
