with either an impressed current or a
galvanic anode system. Ask the
Installation contractor or review as-built
drawings to determine which type of system
you have.
Keep records of system installation, triennial
testing, integrity assessments, and repairs
to help determine whether your system is in
compliance with the corrosion protection
requirements.
