Installation Notes

This riser is intended for use with compression stops and standard faucet inlets. When cutting the PEX tube to length, ensure a clean, square cut to maintain seal integrity. The formed nosepiece eliminates the need for a separate insert at the compression end. Avoid overtightening during compression fitting installation to prevent damage to the sealing surfaces.

Contractor Use

The P1-30A is suitable for new construction, repipe, and retrofit projects requiring quick, code-compliant faucet connections. It meets performance requirements for pressure and temperature in residential plumbing systems and supports uniform routing in tight spaces thanks to its bend radius flexibility.
