pointing down (to allow for proper drainage).

primer to a competitive pump. Contact Hale Customer Service for addi-

❑ Suction connection to priming valve is 3/4” NPT.
❑ A shut-off valve, i.e., Hale PVG or SPV Priming Valve, must be located in
the priming line between the primer pump and the main pump.
