Product review (5 stars): The line insert prevents better engagement.
Replaced a Kitchenaid water/ice maker solenoid valve that was no longer available with the 2182106 valve.  The kit included a mounting piece that attached the solenoid valve to the refrigerator housing.  The ice maker now works after being out of service for want of the part for 2 years.  The water dispenser doesn't drip any more.  Only one problem the small plastic line is only engaged by about 2 or 3 threads.  The line insert prevents better engagement.
