Test Procedure:
UTILITY & ENVIRONMENTAL SERVICES, INC,
LOW PRESSURE AIR TEST POR GRAVITY SANITARY SEWER
Each section of sewer shall be tested between sucesslve 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
~o 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
lr~e line Pressure in the pipe shall not be allowed to exceed 5 psi,
Afler the temperature has stabilized and no air leaks at the plugs have been found, the air pressure
shall be used to determine the 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
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.
