The kit restores proper raw water flow to the powerhead, preventing the overheating that follows a worn or cracked impeller, a hardened housing gasket, or a corroded wear plate. Because it is supplied as a complete kit rather than a single component, it lets an installer replace every wear item in the water pump assembly in one job instead of ordering parts piecemeal and risking a mismatch.\u003c\/p\u003e\u003cp\u003eSierra builds this kit to meet or exceed the specifications of the original equipment part it replaces, and it is backed by Sierra's standard limited warranty.
