The line filter # 12319004 does this have the "y" connection with it?
Answer John, no the line filter 12319004 does not include the Y connection. This outlet line. The inlet line has discontinued the Y connection and is now the valve, part number 12544001. This includes instructions for installation. Thanks!
Also, how do you detach the existing water line from the elbow connection on the filter head assembly?
Answer Hello David. Press in on the compression rings around the tube and when pressed in, the tube will pull out of the fitting.
