Installation & Maintenance Tips
- Mark insertion depth before gluing so joints seat fully during assembly.
- For best bond strength, keep sockets and pipe ends clean and dry during cementing.
- If you expect frequent equipment removal, use a union nearby instead of relying on a glued coupling.
- After startup, inspect joints for seepage and correct any alignment/support issues immediately.
