So I’m trying to replace the line under my bathroom sink. The red one was the original. The green one is the new one. I connected it fine but when I go to turn on the water it sprays from the 3/8 side connected to the water. Did they give me the wrong hose? Do I need a FIP to FIP piece? Is it not supposed to be compression? Thank you for your help!!!
