ABSTRACT A submersible pump check valve having a housing connected to the discharge port of a submerged pump has a poppet retained by four legs operable as cantilever springs and which interact with cam surfaces within the housing to prevent removal during normal operation of the pump but to afford selective removal from the housing for cleaning or replacement of the sealing ring without removing said housing from said submerged pump. Further, the pump need not be removed or otherwise disassembled to remove the poppet.
