H. Pipe protection: provide protection against abrasion where copper tubing is in contact with other building
members by wrapping with an approved tape, pipe insulation, or otherwise suitable method of isolation.
I. Penetration protection: provide allowance for thermal expansion and contraction of copper tubing passing
through a wall, floor, ceiling, or partition by wrapping with an approved tape or pipe insulation or by installing
through an appropriately sized sleeve. Penetrations for fire resistant rated assemblies shall maintain the rating of
the assembly.
J. Backfill material: backfill material shall not include any ashes, cinders, refuse, stones, boulders, or other materials
which can damage or break the tubing or promote corrosive action in any trench or excavation in which tubing is
installed.
K. Horizontal support: install hangers for horizontal piping in accordance with MSS-SP-58.
L. Vertical support: vertical copper tubing shall be supported at each floor.
M. Galvanic corrosion: hangers and supports shall be either copper or vinyl coated to prevent galvanic corrosion
between the tubing and the supporting member.
N. Seismic restraint: in seismic areas, copper tubing shall be installed to withstand all seismic forces.
O. Piping identification: copper tubing systems shall be identified in accordance with the requirements of ASME A13.1.
3.5 Field Quality Control
A. Water testing: the copper tubing system shall be water tested for joint tightness. The piping system shall be filled
with water. The system shall be pressurized to the maximum pressure and length of time required by the code or
standard. The system shall have no leaks at the rated pressure.
B. Air testing: the copper tubing system shall be air tested for joint tightness. The piping system shall be
pressurized with air to the maximum pressure of the system or to the code or standard required minimum for the
required length of time. The system shall have no leaks at the rated pressure.
3.6 Cleaning (Potable Water Systems)
A. Disinfection: the copper hot and cold water distribution system shall be disinfected prior to being placed in
service. The system shall be disinfected in accordance with AWWA C651 or the following requirements:
1. The piping system shall be 󶈶ushed with potable water until discolored water does not appear at any of the outlets.
2. The system shall be 󶈵lled with a water chlorine solution containing at least 50 parts per million of chlorine.
The system shall be valved o󶈴 and allowed to stand for 24 hours or the system shall be 󶈵lled with a water
chlorine solution containing at least 200 parts per million of chlorine. The system shall be valved o󶈴 and
allowed to stand for 3 hours.
3. Following the standing time, the system shall be 󶈶ushed with water until the chlorine is purged from the system.
