On a pump it sits at the strainer pot flange, which is the joint the suction side depends on to stay airtight.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe symptom it fixes\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA pump that will not hold prime, or that weeps at the housing, very often has a flattened, cracked or hardened flange o-ring. It is the cheapest thing on the pad to replace and the first one worth ruling out.
