LOW PRESSURE AIR TEST FOR GRAVITY SANITARY S 'OR --
Test Procedures : Each section of sewer shall be tested between successive manholes g " -
Air shall be introduced into the pipeline until 4.0 psi gauge pressure has been reams At that time the flow f air
shall be reduced and the internal air pressure shall be maintained between 3.5 and 4.5 psi g igerfor at least two(2)minutes 11 .11• • A +1 - Y- 1 - 1• Y• • V1 11 • •11 ,• A A 1" /" • 1 • A 11.11- ,•. -Y:i1 i� 1 _A - `1'111 /"
constantly monitored by a gauge and hose arrangement separate from the hose used to introduce air` thane. 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 make corrections to reduce the leakage to
acceptable limits.
