Installation & Maintenance Tips
Keep sockets and pipe ends clean and dry during assembly; moisture and debris can weaken solvent-weld joints.
For best results, use fresh primer/cement and follow the cement manufacturers cure-time chart before starting the system.
Avoid using the tee as a structural support pointpipe strain can lead to hairline cracks over time.
If you expect future equipment removal, add unions nearby to avoid cutting pipe later.
After startup, inspect joints for seepage and address any pipe stress or misalignment immediately.
