Replaced old Dual Water Inlet Valve.
Turned off water supply.
Unplugged refrigerator.
Removed two 1/4 inch screws with nut driver.
Removed both water lines going from Valve to fridge. (By Hand)
Removed line going from wall to Valve with Adjustable wrench.
Unplugged both Wire harness. (Nice that they are two different sizes so you can't mix them up.)
Reversed the order to install the new one.
One note: I did add some Teflon tape to the new unit for the water supply.
Real easy to do. Did NOT have to cut water lines as the new valve was threaded so they just screwed back on. Did NOT have to separate the two housings as the unit was all in one unit.
Thank You.
