Abstract

A drainage system with filter connection includes a water pump body, a water inlet pipe connected to the water pump body, a water outlet pipe connectable to the water inlet pipe in an orientation forming an annular cavity between an inner surface of the water outlet pipe and an outer surface of the water inlet pipe, a water storage apparatus in communication with the water outlet pipe, a connection fastener for connecting the water inlet pipe and the water outlet pipe to form the annular cavity, and a filter disposed at least partially within the annular cavity. A locating ring is on the periphery of the filter, a cross-section width (W) of the locating ring being greater than a spacing (L) between a front end surface of the connection fastener and a stop surface on the water storage apparatus.
