Deflate stopper #2.

2) Back pressure stopper #4 through the system pressure ports in towers #3 and #4.

3) Deflate stopper #4.

4) Equalize pressure on stoppers #1 and #3 through the by-pass / vent port between towers #3 and #4.

5) Use the by-pass / vent port in tower #1 or #2 to purge air from repaired area.

6) Use system pressure gauge on tower #1 or #2 to determine stoppers are equalized.

7)
