How To: Install FIP Supply Stops

SharkBite supply stops are made of high-quality brass to reduce corrosion and allow for a full flow of water. They’re also easy to install and operate, featuring a 1/4 in. turn for shut-off. Learn how to install a female iron pipe supply stop valve on a 1/2 in. iron pipe stub-out.  

Prepare for Installation

• Check to see if your stub-out comes out of the wall or floor. 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.

Installation Steps

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. Apply plumber’s tape or compound to the iron pipe per the instructions, then thread on the valve.  
4. Carefully tighten the supply stop with a wrench and position the valve to align with the fixture.  
5. Install your faucet or toilet connector from the stop valve to your fixture.  
6. Hand-tighten the nut until snug, then tighten 1/4 in. turn using a wrench. Be careful not to overtighten.  
7. Turn the stop valve to the open position followed by the main water supply.  
8. Check to see that there are no leaks or loose connections.
