The hand manipulatable sprayer (10) is connectable to a container (26) and includes a body (12) having a pump assembly (120) and a check valve assembly (90). The check valve assembly (90) includes at least one conically-shaped skirt valve member (100,112). Also the body (12) can have a cavity (68) adapted to receive similarly shaped inserts (67) for different valve assemblies (90), a cylindrical cavity (68) for receiving various size pistons (34) together with a mating cylindrical insert (43) and a nose formation (15,142,143) adapted to receive nozzle assemblies (14) similarly shaped but of different types and a passageway (96,97) extending from the cavity (68) to and opening on the nose formation (15).
