13Simultaneous Procedure: testing (eont'd.) • Join all connections of the primary system. An optional pressure test may be performed once this step is completed to assure integrity of the line while connections are visible. Example: • Complete closure of the containment system. Primary is pressurized to 50 psi; • Connect pressure gauges to each portion (primary and containment) of the system. These containment to 30 psi. The differ- gauges should have full-scale readings no greater than two times the test pressure or to the ential of 20 psi is enough to detect higher pressure of either system, whichever is greater. any communication between the • Pressurize the primary system to its intended test pressure and close off the source to two lines.

Should the pressure drop in the containment during this time, re -pressurize and check integrity before other steps are taken. Movement of the piping during backfilling may cause the system to burp slightly. The seal of the 0 -ring gasket will be regained when the movement stops. The system can be re -pressurized without concern. 14 Health and safety Toxicity of adhesive information Hardener.
