Vacuum testing in the presence of ground water Vacuum testing after backfilling should be performed only after a successful nonbackfill test has been completed in accordance with ASTM C Search book title Enter keywords for book title search. Need more than one copy? The values recorded are applicable only to the manhole being tested and at the time of testing. Adjusting vacuum pressure Most flexible connectors have a pressure rating of only 10 psi when deflected, which is fairly common in a field installation; therefore we will use the more conservative 10 psi pressure rating as a base point.
