Like others have said, it's probably the flapper valves. However, it could be the sealing surfaces have corroded if it's an alloy pump. If that's the case, you're in it for a new pump. You probably won't know until you take it apart.
If it's an alloy pump, coat the sealing surfaces with TefGel before re-assembly. Dennis C.
