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.
