2.4 Connecting to the Underground Return Pipework
The recovered vapour is returned to the underground storage tanks from the dispenser
vapour sensors via flametraps housed in a tee junction, which must be connected to
the underground return pipeline.
Gallagher Fuel Systems recommends that the vapour return lines be connected via a
ball-valve or other suitable isolating device, as shown in the illustration below.
This may require removal of the existing connection to facilitate a shortening of the
hose.
When replacing the connection it should be sealed using self-vulcanising tape.
