INSTALLATION PROCEDURES
A joint should not be pressure tested until it has cured. The
exact curing time varies with temperature, humidity, and
pipe size. The presence of hot water extends the cure time
required for pressure testing. Pressurization prior to joint
curing may result in system failure.
