MANHOLE VACUUM TEST REPORTS
Test Procedures
Plug all manhole entrances and exits other than the manhole top access using suitably sized pneumatic or
mechanical pipeline plugs. Install the vacuum tester head assembly at the top access of manhole. Attach
vacuum pump to test bead and start pump. Open Inlet/outlet ball valve and evacuate the manhole to 10" Hg.
(Approximately negative 5 PSIG, 0.3 bar) Close vacuum inlet/outlet ball valve and monitor vacuum for specified
test period.

LOW PRESSURE AIR TEST FOR GRAVITY SANITARY SEWER
Test Procedures: Each section of sewer shall be tested between successive manholes,
Air shall be introduced into the pipeline until 4.0 psi gauge pressure has been reached. At that
time the flow of air shall be reduced and the internal air pressure shall be maintained between 3.5 and 4.5
psi gauge for at least two (2) minutes to allow the air temperature to come to equilibrium with the
temperature of the pipe walls_ Pressure in the pipe shall be constantly monitored by a gauge and hose
arrangement separate from the hose used to introduce air into the line. Pressure in the pipe shall not be
allowed to exceed 5 psi.
After the temperature has stabilized and no air leaks at the plugs have been found, the air pressure
shall be used to determine that time lapse required for the air pressure to drop to 2.5 psi gauge.
If the time lapse required for the air pressure to decrease from 3.5 to 2.5 psi exceeds that shown in
the following table, the pipe shall be presumed to be within acceptable limits for leakage.
If the time lapsed is less than that shown in the table, the contractor shall snake corrections to reduce
the leakage to acceptable limits.
