Installation & Maintenance Tips
- Solvent-weld the socket ends to PVC pipe using proper PVC primer and cement. Allow full cure before pressurizing.
- When tightening the union nut, hand-tighten firmly — avoid over-tightening to prevent stress on the valve body.
- Operate the valve at least once or twice per season to ensure smooth operation and prevent sticking.
- Inspect the union flange and O-ring periodically for leaks; replace the O-ring if chemical damage or wear is evident.
