LOW PRESSURE AIR TEST FOR GRAVITY SANITARY/~$1;i4 k}
Test Procedures '
Each section of sewer shall be tested between successive manholes. ~k~'& ~ _ , "7
Air shall be introduced into the pipeline until 4.0 psi gauge pressure has been reached. ~t t~t ti, m, e ~e~t_!_o,wt~Oj/
air shall be reduced and the internal air pressure shall be maintained between 3.5 and 4.5 psi gaug"C~Ot ~[ ~
minutes to allow the air temperature to come to equilibrium with the temperature oftbe pipe walls. Pr'L,s~ut~I.iadl~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.
lfthe 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 eorreetions to reduce the leakage
to acceptable limits.
