9. Install valve at tapped coupling.

Notes:

1. The Certa-Set main line piping and couplings can be disassembled and reused. See Main Line

Disassembly.

2. Tapped couplings can be easily stripped if threads are not aligned properly. Take precautionary steps to

prevent cross threading.

Best Practices:

Turn the pipe backward so the female end drops in, then tighten. This eliminates stripped threads.
