4. Installation Instructions
Follow these steps for proper installation of your PROFLO PFXQAPP32C Angle Stop Valve.
- Prepare the Work Area: Turn off the main water supply to the building. Open a faucet at the lowest point in the house to drain the water lines. Clear the area around the existing stop valve or pipe connection point.
- Remove Old Valve (if applicable): If replacing an existing valve, use a wrench to carefully loosen and remove it. Clean any debris from the pipe end.
- Prepare PEX Connection: For the 1/2" PEX inlet, ensure the PEX pipe end is cut cleanly and free of burrs. Follow PEX manufacturer guidelines for crimp or clamp ring installation.
- Install the Angle Stop Valve:
- Slide the appropriate PEX crimp ring or clamp onto the PEX pipe.
- Insert the PEX end of the angle stop valve fully into the PEX pipe.
- Position the crimp ring or clamp over the PEX connection and secure it using the correct PEX crimping or clamping tool. Ensure a watertight seal.
- Connect Supply Line: For the 3/8" OD compression outlet, slide the compression nut and then the compression sleeve (ferrule) onto the supply line (e.g., faucet supply line). Insert the supply line into the valve's compression outlet. Hand-tighten the compression nut, then use a wrench to tighten it an additional 1/2 to 3/4 turn. Do not overtighten.
- Check for Leaks: Slowly turn the main water supply back on. Inspect all connections for leaks. If leaks are detected, tighten the connections slightly until the leak stops.

5. Operation
The PROFLO PFXQAPP32C Angle Stop Valve features a quarter-turn lever handle for easy operation.
- To Open the Valve: Turn the lever handle 90 degrees (a quarter turn) so it is parallel with the water pipe. This allows water to flow through the valve.
- To Close the Valve: Turn the lever handle 90 degrees (a quarter turn) so it is perpendicular to the water pipe. This stops the water flow through the valve.
The quarter-turn design provides quick and reliable shut-off.
6. Maintenance
The PROFLO PFXQAPP32C Angle Stop Valve is designed for long-lasting performance with minimal maintenance.
- Regular Inspection: Periodically check the valve and connections for any signs of leaks, corrosion, or damage.
- Cleaning: Clean the exterior of the valve with a soft cloth and mild soap and water. Avoid abrasive cleaners or harsh chemicals, as these can damage the chrome finish.
- Exercising the Valve: If the valve is rarely used, it is recommended to open and close it completely once or twice a year to prevent mineral buildup and ensure smooth operation.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Water leak at connections | Loose compression nut or improper PEX connection. | Turn off water supply. Carefully tighten compression nut or re-crimp PEX connection. Ensure compression sleeve is correctly seated. |
| No water flow | Valve is closed; main water supply is off; blockage. | Ensure valve handle is parallel to the pipe. Check if main water supply is on. Inspect for any visible blockages in the supply line. |
| Valve handle is stiff | Mineral buildup or lack of use. | Gently open and close the valve several times. If stiffness persists, replacement may be necessary. |
