The pipe should not be anchored tightly by the support, but secured
in a manner to allow for movement caused by thermal expansion
and contraction. It is recommended that you use clamps or straps
that allow pipe to remain away from the framing, thus reducing the
noise generated when pipe is allowed to rub against wood.
