Failure to compensate for expansion and contraction
caused by temperature change may result in system
failure and property damage.
• Do not restrict expansion or contraction. Restraining
movement in piping systems is not recommended and
may result in joint or fitting failure.
• Use straps or clamps that allow for piping system
movement.
• Align all piping system components properly without
strain. Do not bend or pull pipe into position after being
solvent welded.
• Do not terminate a pipe run against a stationary object
(example: wall or floor joist).
• Do not install fittings under stress.
