Installation Tips
- Use Proper Sealant: Apply Teflon tape or thread sealant to the FNPT threads to ensure a leak-free connection.
- Secure Solvent Welding: Use approved PVC cement for the spigot end to create a strong, permanent bond.
- Maintain Accessibility: Install in an area where cleanout access remains easy after wall or floor finishes are applied.
- Protect from Heat: Avoid prolonged exposure to temperatures above 140 °F or direct sunlight to prevent warping.
