Check the oil chamber during routine maintenance. Discolored or milky oil, motor thermal trips, and visible moisture on the pump housing are all signs this sewage pump seal kit is due for replacement.\u003c\/p\u003e\n\u003ch3\u003eBuy HCP Mechanical Seal Kit S21B250G01 Online from Cleanflow\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCleanflow Utility Supply Company\u003c\/strong\u003e is an authorized \u003ca href=\"https:\/\/cleanflow.net\/collections\/hcp\"\u003eHCP distributor\u003c\/a\u003e.
