I need to replace the water inlet valve, but the current one is connected with copper tubing, and your video shows plastic tubing. Does the replacement valve assembly work with copper tubing? And if so, any tips for making a good connection?
Answer Hello Paul,
The only difference between the connection with a plastic tube and copper is the type of fitting used. The copper one uses a feral fitting. The fitting on the existing line can be reused if checked closely after installation is complete and water pressure is turned back on and no leaks are detected. Use of a paper towel is a common method for checking for leaks since the cold pipe may make it difficult to tell if it is wet or not. If there is even a drip present it is recommended to use a pipe cutter to cut off the end of the copper tube and put on a new nut and feral and tighten it fully. Remember that when the feral is tightened sufficiently, the edges of the new feral are bent into the copper line forming the seal. For this reason, the copper lines have to be tightened more than plastic or other flexible lines.
Can the water inlet valve be taken apart and cleaned? Can the tube to the ice maker be pulled out and pushed back in at this valve? It seems that the valve is not fully shutting off because I find an ice column from a slow drip from the bottom of the ice maker to the ice cubes below. If I break it off twice a day it works fine but if I don't, I get a block of ice in the tray.
Answer Hello Jay,
The water valve cannot be taken apart and re-assembled. If you do this, it will have an external leak that cannot be repaired. The water valve will have to be replaced. The only thing that can cause the valve to not fully close is low water pressure since the water pressure closes the valve, or a bad water valve, (fouled by sedimentation and/or mineral deposits from the water supply). The water line is removed by pushing it into the valve hard and holding the ring around the water line in toward the valve. While holding the ring toward the valve, pull the water line out of the valve. This is called a John Guess fitting. The line is re-installed by pushing it into the valve until it bottoms. Pushing it a bit harder will make the line bottom again. Pulling on the water line at this point seats the seal. As a note, if there is a dip around the water line, it has to be cut off squarely, (about 1/4 of an inch), to prevent a leak since this is where the seal seats. Replacing this valve will correct the issue of the ice column.
