A. Valves shall be installed in such positions that they are readily accessible and can be easily and fully opened without binding. Valves (3 inches and smaller) in enclosures shall be installed with the valve handle on top, plumb and centered unless noted otherwise on the drawings.

3 .4 SERVICE BOXES

A. The valve boxes shall be centered over the valves, water meter and wye strainer. The floor of the excavation on which the box rests shall be compacted in accordance with Section 02320.

3 .5 DRAIN ROCK/HARDWARE CLOTH

A. Once the floor of the box excavation has been compacted and hardware cloth installed, then drain rock shall be placed AS SHOWN ON THE DRAWINGS.

3 .6 DISINFECT ION AND TESTING

A. Perform concurrently with companion water lines and meters; see section 15051.

B. Disinfection: Section 15051.

C. Testing: Section 15053.

15053 - 1

SECTION 15053

TESTING OF WATER LINES

A. Work under this section consists of leak testing water lines, and related valves and fittings.

Rejected work shall be retested. This work is considered incidental to other sections.

1 .2 QUALITY ASSURANCE

A. Water test gauges shall be ANSI B40.1-80, Grade 2A (plus or minus 0.5 percent of full scale accuracy), dial range approximately twice the required test pressure.

1 .3 SUBMITTALS

A. Before testing, provide the following information:

1. All Tests: Describe precautions that will be taken to protect system equipment that might be damaged under test pressures.

2. High Pressure Water Test: Describe the proposed method for disposal of water used in line testing.

1 .4 PROJECT CONDITIONS

A. Testing shall not be performed until each system has been flushed or thoroughly cleaned in accordance with procedures in the sections that describe water and sewer line installation.

B. Test potable water lines before disinfecting.

C. Water for Flushing and Testing shall be potable water. A water pump may be needed to obtain test pressures. Note: Do not use air pressure for testing PVC water pipe.

PART 3 EXECUTION

2 .1 GENERAL

A. Perform testing in the Contracting Officer's presence after backfill and proper compaction of trenches. Where lines are installed under roadways and parking areas, perform tests after completion of final subgrade preparation and prior to application of surface courses. Notify Contracting Officer at least 48 hours prior to testing.

B. Prepare each section for testing, using adequate bracing; protect system equipment susceptible to damage by test pressures; make provision for installation of Government pressure gauge in parallel with Contractor's gauge, if so requested; and maintain services where required.

2 .2 WATER LINES

A. Fill line with water; eliminate all air by bleeding of air at hydrants, drains etc...

B. Raise the internal pressure by pumping in water to 50 psig above the maximum anticipated service pressure (ignore water hammer) at the point of test gauge attachment for each prospective line for not less than fifteen (15) minutes. This pressure shall be held without

15053 - 2 introducing additional pressure. Prior to testing the waterline shall be partially buried except for fittings in order to observe any leakage during test. A water pump may be needed to obtain test pressures.

Note: Do not use air pressure for testing PVC water pipe.

C. The line section will have passed the test if the pressure does not drop more than 5% of the test pressure. Note: Even if tested in sections a final test for each entire line shall be tested.

D. In the event of test failure, the Contractor shall repair the waterline by replacing defective joints, pipe, fittings, valves, etc., and retest until leakage is corrected.

E. Do not use paints, asphalts, tars, or other types of pipe compounds to eliminate leaks.

F. Replace leaking fittings, nipples, or lengths of pipe.
