2.9.3 Remove all water from pontoon compartment if has any until satisfy.
2.9.4 All compartments of a leaking pontoon must be tested with a pressure between 5 psi to
6 psi to identify the leaking location.
IMPORTANT: It is essential when using a pressure gauge to ensure that the gauge is correctly
calibrated at all times.
Figure 2.17
2.9.5 Install the pressure gauge and air supply valve to drain port of the subjected leakage
compartment (refer to figure 2.18 on next page).
2.9.6 Air is supplied into the compartment until the required test pressure is achieved.
2.9.7 The air is then shut off by closing the supply valve and all welded seams, joints and
connections of the effected compartment are tested with soapy water to determine if
there are any leaks and the location of the leaks.
2.9.8 Where leaks do occur, the leaks area is to be re-welded, and on completion, the air
tested repeated on the compartment effected.
NOTE: This operation must be repeated if necessary until there are no further leaks from the
compartments that are observed.
“The air pressure for the test must be measured by pressure gauges. When a pressure gauge is
used, care must be taken to prevent over pressuring of the compartment. Pressure that more
than 6 psi could over expand the pontoon walls until the limit and will cause the pontoon lose
the original shape”.
