1.7 TESTING REPAIRED SECTIONS

A. Notify the DISTRICT AGRONOMIST/COR five working days in advance of testing.

B. Subject pipelines jointed with rubber gaskets or threaded connections to a pressure test after partial completion of backfill. Pipelines joined with solvent-welded PVC joints will be allowed to cure at least 24 hours before testing.

C. Subsections of mainline pipe may be tested independently, subject to the review of the DISTRICT

AGRONOMIST/COR.

D. Furnish clean, clear water, pumps, labor, fittings, and equipment necessary to conduct tests or retests.

E. Volumetric Leakage Test – Gasketed Mainline Pipe:

1. Backfill to prevent pipe from moving under pressure. Expose couplings and fittings.

2. Purge all air from the pipeline before test.

3. Subject mainline pipe to the anticipated operating pressure of 100 PSI for two hours. Maintain constant pressure. The amount of additional water pumped in during the test will not exceed:

a. 0.82 gallons per 100 joints of 3-inch diameter pipe

b. 1.08 gallons per 100 joints of 4-inch diameter pipe

c. 1.62 gallons per 100 joints for 6-inch diameter pipe

4. Allowable leakage to be calculated using L = (ND√P)/7400 where L = Allowable Leakage N = Number of Joints D = Nominal Diameter of Pipe (inches) P = Average Test Pressure (PSI)

5. If required-replace defective pipe, fitting, joint, valve, or appurtenance. Repeat the test until the pipe passes test.

6. Cement or caulking to seal leaks is prohibited.

F. Hydrostatic Pressure Test – Solvent Weld Lateral Pipe repairs:

1. Subject lateral pipe to a hydrostatic pressure equal to the anticipated operating pressure of

80 PSI for 30 minutes.

2. Leakage will be detected by visual inspection. Replace defective pipe, fitting, joint, valve, or appurtenance. Repeat the test until the pipe passes test.

3. As an alternative to the visual inspection described in Item 4. above, the DISTRICT

AGRONOMIST/COR may request that a pressure drop test be performed:

a. Pressurize the lateral via the remote-control valve then turn down flow control handle on remote control valve to seal off lateral.

b. Observe pressure loss on pressure gauge. If pressure loss is greater than 5 PSI, identify reason for pressure loss. Replace defective pipe, fitting, joint, valve, or appurtenance.

Repeat test until pressure loss is equal to or less than 5 PSI.

4. Cement or caulking to seal leaks is prohibited.

5. After lateral passes test and prior to operational test, install sprinklers and backfill and compact all pipe, fittings, joints, or appurtenance.

G. Operational Test – Remote Control Valves, Lateral Piping and Sprinklers:

1. Activate each remote-control valve in sequence from each controller. Manual operation of the valves from the bleed valve on the remote-control valve is not an acceptable method of activation. The DISTRICT AGRONOMIST/COR will visually observe operation, water application patterns, and leakage.

2. Replace defective remote-control valve, solenoid, wiring, or appurtenance to correct operational deficiencies.

3. Replace, adjust, add, or move water emission devices to correct operational or coverage deficiencies.

4. Replace defective pipe, fitting, joint, valve, sprinkler, or appurtenance to correct leakage problems. Cement or caulking to seal leaks is prohibited.

5. Repeat test(s) until each lateral pass all tests. Repeat tests, replace components, and correct deficiencies at no additional cost to the Owner.

• If at any time the wind exceeds 10 mph, the audit shall be stopped and restarted (cans emptied and started anew) when the wind drops below 5 mph for an extended period, at the discretion of the auditor.

• If a site is being audited that consistently has winds above

10 mph, then the Contractor and National Irrigation Specialist will determine the best course of action to proceed as to the effect of the wind on the audits.

5. Provide all data called for in the irrigation audit worksheets used in the current edition of the

Irrigation Association Landscape Irrigation Auditor Manual.

a. Supply all data in a digital (MS Excel format) as well as paper report format to NCA via DISTRICT AGRONOMIST/COR.

c. Provide copies of all field notes, drawings, and data collection forms used in the field, to be submitted along with the paper report and digital media versions of the audit information.

6. Do not complete the Pre-Audit Inspection Corrective Actions included in the Irrigation

Association Guidelines, as the irrigation system is to be audited in its current condition.

However, pressure is to be checked at the pressure regulating device on each valve tested by using a Schrader valve compatible connection and liquid filled pressure gauge. If there is no pressure regulating valve, the closest sprinkler to the RCV will be checked using a pitot tube and liquid filled pressure gauge.

7. Based on the area being audited, the Contractor shall use several catch cans that is divisible by 4, with a minimum of 28 catch cans being used for each audit.

8. Catch cans shall be laid out in a grid format per the current edition of Irrigation Association
