8.0 Retrieving MDS Stopper:
NOTE: Always equalize pressure
on both sides of the stopper before
deflation or removal.
After the work on the pipeline is complete,
equalize the pressure behind the MDS Stopper and
in front of the MDS Stopper.
This can be done in a variety of ways. Refer to
examples in Section 3.0 of this manual and your
gas company procedures.
* ALWAYS EQUALIZE PRESSURE *
Once pressure is equalized, open the inflation
valve of the MDS Stopper to deflate the stopper.
Pressure inside the pipeline will assist with the
evacuation.
Connect the hand pump to the stopper inflation
connection and pull a vacuum on the stopper to
make it as compact as possible.
