4.	Check-valve failure in service lines is difficult to diagnose and may misrepresent mainline integrity.
a.	Close service line connections until mainline testing is completed.
b.	Accurate records must be kept ensuring service line connections have been opened after mainline system has been approved.
5.	Avoid testing lengthy line segments.
a.	Lengthy line segments may pass leakage test, yet still have an excessive isolated leak which could be a problem.
b.	Testing shorter line segments reduces this possibility and more readily isolates any leaks.
c.	Best practice is to limit the test segment length to 12,000/D, where "D" is the diameter in inches and the length of segment is in feet.
6.	Air must be purged from line section prior to hydrostatic testing. Failure to do so may give misleading test results, possibly causing a section of line to appear to fail the test.
