it is characterized in that the method comprises the steps of,
a venting device (700) is provided at an upstream end of the exhaust manifold (100), the venting device (700) being configured to communicate the exhaust manifold interior and exterior (100) when the plurality of pressure sensing devices are in operation to allow for the generation of an airflow within the exhaust manifold (100).
5. The waste line system (10) of claim 1,
it is characterized in that the method comprises the steps of,
the auxiliary flushing device (600) is arranged on the waste branch pipe (300) downstream of the corresponding dirt generating device (400) for auxiliary flushing to the waste main pipe (100) via the corresponding waste branch pipe (300).
6. The waste line system (10) of claim 1,
it is characterized in that the method comprises the steps of,
the auxiliary flushing device (600) comprises an air inlet assembly (610) and/or a cleaning agent feeding assembly (620), wherein the air inlet assembly (610) is used for introducing external air for auxiliary flushing, and the cleaning agent feeding assembly (620) is used for feeding cleaning agent into the waste discharge branch pipe (300) for auxiliary flushing.
7. The waste pipe system (10) according to claim 6,
it is characterized in that the method comprises the steps of,

8. A method of auxiliary flushing using a waste line system (10) according to any of claims 1 to 7, the method comprising the steps of:
detecting whether dirt remains in the waste main (100) through a residual dirt detection device (500) arranged along the waste main (100);
if it is detected that a pipe section with dirt residue exists in the waste main pipe (100), at least an auxiliary flushing device (600) upstream of the most upstream pipe section with dirt residue is activated to perform auxiliary flushing.
9. The method according to claim 8, wherein the method comprises,
it is characterized in that the method comprises the steps of,
the detection step is started 10 seconds after the normal flushing cycle of the soil producing device (400) has ended.
