observe the tests specified below and to insure compliance with the
requirements of the plumbing code.
3. Re-inspections: Whenever the piping system fails to pass the test or inspection, make
the required corrections, and arrange for re-inspection by the plumbing official.
4. Reports: Prepare inspection reports, signed by the plumbing official.
B. Piping System Test drainage and vent system as follows:
1. Test for leaks and defects in all new drainage and vent piping systems and parts of

THE KENT
2. Leave uncovered and unconcealed all new, altered, extended, or replaced drainage
and vent piping until it has been tested and approved. Expose all such work for
testing that has been covered or concealed before it has been tested and approved.
3. Rough Plumbing Test Procedure: Except for outside leaders and perforated or open

water. Water column shall be maintained for 4 hours with no leaks. Water level shall
not drop during the period from 15 minutes before the inspection starts, through
completion of the inspection. Inspect all joints for leaks.
4. Finished Plumbing Test Procedure: After the plumbing fixtures have been set and
their traps filled with water, their connections shall be tested and proved gas and
water-tight. Plug the stack openings on the roof and building drain where it leaves the
building, and introduce air into the system equal to a pressure of 1" water column.
Use a "U" tube or manometer inserted in the trap of a water closet to measure this
pressure. Air pressure shall remain constant without the introduction of additional air
throughout the period of inspection. Inspect all plumbing fixture connections for gas
and water leaks.
5. Repair all leaks and defects using new materials and retest system or portion thereof
until satisfactory results are obtained.
