Electric water shut off valve with 5/8" inlet/outlet. This service replacement valve package is intended to replace the old version of the electric water valve in your electronic controlled heater valve. Currently there are two variations of this valve in use. The difference is the arrangement of terminals. Old style valves have a distinct 't' pattern, while new style valves have the terminals located in the four corner positions. All replacement valves supplied in 54-560 assembly are the new style of valve with the 4-corner pin pattern. The jumper harness in this kit allows the new valve to work with the mating harness for the older version. Instructions included.
