A pump module for a recirculating pet fountain having a module housing in which a pump is received in which a filter can also be removably received. The module includes a perforate intake formed in a surface of the housing located adjacent to and generally facing toward a bottom of a fountain basin in which the module is removably mounted helping to keep debris and the like from entering the module and plugging the filter. In one embodiment, the intake is a perforate grate integrally formed in a generally downwardly facing surface of the housing and the module is configured so water enters through the intake and flows upwardly through the filter before entering the pump. The downwardly facing surface of the module housing is configured so some intake perforations are closer to the basin bottom than others helping ensure at least one perforation remains under water and substantially unplugged.
