Installation & Compatibility Notes
Before installation, shut off system flow and relieve pressure. Hand-thread the union onto the 1½″ male equipment port, ensuring the gasket sits properly in the sealing face. Solvent-weld the 2″ socket side to the plumbing line, align the union and tighten the union nut until the gasket seals. Avoid overtightening. Restore flow and confirm a leak-free connection.
Maintenance Tips
- Inspect the union and gasket during seasonal service for cracking, deformation or chemical wear.
- If equipment is frequently removed, verify alignment of the tailpiece to prevent strain or leaking.
- Replace the union if the gasket no longer seals or if the body shows heat-related distortion.
