Replace it outright, rather than cleaning it, once the fins or shaft show visible wear or cracking, or the pump starts rattling.\u003c\/p\u003e\u003ch3\u003eCommon questions\u003c\/h3\u003e\u003ch4\u003eHow do I know my impeller needs replacing?\u003c\/h4\u003e\u003cp\u003eReduced or stopped water flow, a grinding or rattling noise from the filter cube, or the pump failing to restart after cleaning are the usual signs.
