New Faucet doesn't match old water lines

Author: sayzor (MS)

Okay, I live in a about 15 year old house (trailer, technically). I needed to replace my faucet so I bought one that had the pulley-spout sprayer. It seemed nice, but i went to install it and realized the water lines do not match up at all. The new one has 3/8 inch connectors that screw on. But the old one had plastic pipes (aboutt 1/2 inch that connected directly to the handles of the last faucet) that came up from the water knobs on the floor. I took the plastic pipe off of the water knob because i assumed that it would have a place to screw the new one in. But it turns out that the spot on the water knob was completely smooth and had no place to screw anything on or into it. I have no idea how to use the faucet. I took a bunch of photos but I don't know how to add them on here

Since you've disconnected the PEX from the valve, you'll need to shut the water off to the house. Next, cut both hot and cold pipes below both existing valves (which means working below floor level- I would enlarge the cabinet floor cutout rather than opening up the vapor barrier and floor below). Take the left over PEX tube and connect to both lines below floor with SharkBite couplings. Cut the tubes about 9-12" off the cabinet floor. Install SharkBite X compression stops with 3/8" compression on outlet of valve. Connect new faucet supplies to valves. Turn water on to house.
