Customer Questions and Answers for Water Valve Single by Whirlpool

Hello Jerry, These are called John Guess fittings. They were very criticized by technicians for several years, until they proved they wouldn't be constant sources of leaks as the techs. thought they would be. They are really simple to use. To remove a water line, you push the line into the valve pretty hard and push the ring around it toward the valve assembly. While you hold the ring in, pull the water line out. Now to reconnect the water line, push the water line into the hole and then push harder. You can feel the water line "pop" a little further into the assembly. To seal the line, simply pull on the water line and it will not come out if it's pushed in far enough. Just a note here to avoid having to learn the hard way. Before putting the water line in the John Guess fitting, inspect the water line and ensure there's no abnormalities on the outside of the water line within about 1/2 inch from the end of the line from previous installation. If there is, the end of the line needs to be cut off squarely so no water can seep out from the sealing area.
