Abstract: A drainage system includes a water pump body, a water pump body water inlet pipe, a water outlet pipe, a water storage apparatus and a connection fastener. The connection fastener is connected to the water inlet pipe and the water outlet pipe, the water inlet pipe and the water outlet pipe are being joined embedded to form an annular cavity. The inside of the annular cavity includes a filter, the periphery of the filter having a locating ring, the cross-section width of the locating ring is greater than the spacing between the front end surface of the connection fastener and a stop surface, and the connection fastener includes a clamping apparatus. If a user forgets to mount the filter, the annular cavity between the water inlet pipe and the water outlet pipe makes the connection between the water pump and the water storage apparatus unstable.
