How To: Install CPVC Supply Stops

Watch How to Install a SharkBite Supply Stop Valve for CPVC Pipe on YouTube.

SharkBite supply stops help you control water flow to specific fixtures and appliances without shutting off water to the entire home. Learn how to install a CPVC supply stop valve on a 1/2in. CPVC stub-out.

Prepare for Installation  

  • Locate your stub-outs. They will either be on the wall or the floor.  
  • Choose the correct stop valve. Use an angle stop valve for wall applications and a straight stop valve for floor applications.
  • Check to see if you will need one or two stop valves.

How to Install SharkBite CPVC Supply Stops

  1. Shut off the water supply by using the main water shut-off to the structure. Open a nearby faucet to continue to relieve pressure and drain the supply line.
  2. If necessary, disconnect any remaining supply lines and remove old stop valves.
  3. Cut the CPVC stub-out squarely and apply CPVC all-in-one or primer and cement to both the end of the CPVC pipe and the inside of the valve. Be sure not to over-apply.  
  4. Push the valve onto the pipe then turn it 90 degrees to align it with the fixture.  
  5. Allow the joint to cure according to the solvent’s instructions.  
  6. Install your faucet or toilet connector from the stop valve to your fixture.  
  7. Hand-tighten the nut until snug, then using a wrench, tighten 1/4 in. turn. Be careful not to overtighten.
  8. Turn your stop valve to the open position, then open the main water supply.
  9. Check to see that there are no leaks or loose connections.
