How To: Install Push-to-Connect Supply Stop Valves

SharkBite offers push-to-connect supply stop valves that connect PEX, copper, CPVC and HDPE water supply lines for faucets, toilets, refrigerators, dishwashers, ice makers, and humidifiers. These push-to-connect stop valves range from single valves and connection kits with separate pieces to one-piece connectors for toilets and faucets that make the job quick. 

How to Install SharkBite Push-to-Connect Supply Stop Valves

1. Identify the stub-out. Determine if your stub-out comes out of the wall or floor. If it comes out of the wall, you’ll need an angle stop valve. If it comes out of the floor, you’ll need a straight stop valve. Some projects require one stop valve while others require two, so be sure to get the appropriate amount before beginning your project.   
2. Shut off the water. The safest way to do this is through the main water shut-off. Then, continue to relieve pressure and drain the supply lines by opening a nearby faucet. If necessary, disconnect any old supply lines and remove old stop valves. 
3. Cut the stub-out squarely. Make sure to leave enough pipe to insert the supply stop. If you’re working with a copper stub-out, make sure to deburr the pipe.  
4. Mark the depth and install the valve. Using a deburr and gauge tool, mark the proper depth on the stub-out. Push the supply stop valve onto the pipe to the mark. 
5. Connect the stop valve to the fixture. Finish by connecting the supply stop valve to the fixture. Hand-tighten the nut until snug and then, using a wrench, tighten one quarter-turn. Be sure not to overtighten.  
6. Test the connection. Turn the supply stop valve to the open position then turn on the main water line. Check to ensure there are no leaks or loose connections.
