18-29-312.2  Drainage and vent water test.

 The water pressure test for plumbing shall be applied byclosing the lower end of the vertical pipes and filling the pipes to the highestopening above the roof with water. The air pressure test for plumbing shall beapplied with a force pump and mercury column equal to 10 inches (250 mm) ofmercury. The use of spring gauges is prohibited. Special provision shall be madeto include all joints and connections to the finished line or face of floors orside walls, so that all vents or revents, including lead work, may be testedwith the main stacks. All pipes shall remain uncovered in every part until theyhave successfully passed the test.

18-29-312.4  Deliberately omitted.

18-29-312.5  Water supply system test.

 Upon completion of a section of or the entire watersupply system, the system, or portion completed, shall be tested and provedtight under a water pressure not less than the working pressure of the system;or by an air test of not less than 50 psi (344 kpa). The water utilized fortests shall be obtained from a potable source of supply. The required testsshall be performed in accordance with this section and Section 18-29-606.6.

18-29-312.6  Gravity sewer test.

Gravity sewer tests shall consist of plugging the end of the building sewer at the last downstream structure before the public main,filling the building sewer with water, testing with not less than a 10 ft (3.05m) head of water, and maintaining such pressure or level for 15 minutes.

18-29-312.7  Forced sewer test.

Forced sewer tests shall consist of plugging the end of the building sewer at the last downstream structure before the public main andapplying a pressure of 5 psi (34.5 kPa) greater than the pump rating, andmaintaining such pressure for 15 minutes.

18-29-312.8 Storm drainage system test.

Storm drain systems within a building shall be tested by water or air in accordance with Section 18-29-312.2.

18-29-312.9 Cross connection control device inspections.

The department of water shall inspect back flow prevention assemblies to determine proper installation including testing by a licensed Cross Connection Control Device Inspector. Reduced pressure principle back flow preventer assemblies, double check-valve assemblies, double-detector check-valve assemblies and pressure vacuum breaker assemblies shall be tested at minimum,annually, the results of annual tests shall be reported within 30 days of tests to the department of water. In the event of test failure, immediate notification must be made to the department of water and remedial action taken to prevent the contamination of the potable water supply. The testing procedure shall be performed in accordance with one of the following standards:
