Installing a saddle valve for your Whirlpool reverse osmosis system

• Shut off the main water valve for your house and open faucets to bleed off water pressure from the cold water pipes.
• When attaching the saddle valve to iron pipe, drill a 1/8-inch hole for the valve pin.
• Connect the needle valve to the pipe.
• For copper or plastic pipes, carefully turn the valve handle to pierce the pipe. For an iron pipe, turn the valve handle to shut the valve.

• Disconnect the water line from the quick-disconnect fitting.
• Using a small slot screwdriver, remove the collet and O-ring from the quick-disconnect water fitting.
• Clean the port of the disconnect fitting.
• Lubricate and insert the new O-ring into the bottom of the port. Push the collet into the port until it locks in place.
• Reinstall the water line and turn on the water supply going to the reverse osmosis system.
