21 year old Doulbe Outlet Water Valve (plastic housing) sprung a leak

Turn off water supply line. Use Nut Driver to remove bolt holding assembly to the fridge. Disconnect (2) electrical connectors. Use wrench to disconnect water supply line, (NOTE: Since this unit is a universal type replacement, it did not re-mount to the fridge in the same fashion as the old assembly. I had to play with it to determine how to mount the new assembly in order to align & pick-up the existing bolt hole). Snap on the provided electrical connector adapter prongs and reconnect both connectors. Apply teflon tape on threads of water supply line fitting (optional). Tighten (do not over-tightened) water supply line to assembly (wrench). Use dikes to cut off compression fittings from both the ice and chilled water dispenser lines. Push lines into assembly. Re-mount assembly to fridge. Turn on water supply line. Check for leaks.
