WARNING
DO NOT operate a pump with a relief valve that is not positioned correctly. The relief valve will be
inoperable. This can allow high pressure buildup on the discharge side of the pump and in the system
downstream of the pump. High pressure can cause the pump or any other system component to break or
leak causing liquid in the system to escape, resulting in possible injury or death.
NOTE: The fact that the pump has the correct rotation and pumps liquid in the correct direction does not insure
that the relief valve is installed in the correct position, or that it has the correct setting for the application.
NOTE: Some older RV style faceplates do not have the word “INLET” cast into the faceplate; however, the
position of the relief valve is the same, i.e., relief valve cap and adjusting screw are offset to the discharge side of
the pump.
