It is the seal that sits between the two housing halves and keeps the pump from leaking at the seam.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy it fails\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA booster pump O-Ring lives between heat, pressure and chlorinated water. Over a few seasons it takes a permanent set, loses its round section and stops springing back against the groove. The first sign is usually a slow weep at the housing joint that turns into a steady drip, and the pump can start losing prime once air gets past the same gap.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eClean the groove and the mating face before the new ring goes in, so it lies flat all the way round with nothing trapped under it.
