and couplings according to manufacturer's written instructions for use of lubricants, cements,

and other installation requirements.

334100 - 3

1. Install piping pitched down in direction of flow. 2. Install piping NPS 6 (DN 150) and larger with restrained joints at tee fittings and at

joints.

2. Join dissimilar pipe materials with nonpressure-type flexible couplings.

3.4 CLEANOUT INSTALLATION

to cleanouts. Install piping so cleanouts open in direction of flow in sewer pipe.

1. Use Light-Duty, top-loading classification cleanouts in earth or unpaved foot-traffic areas.

2. Use Medium-Duty, top-loading classification cleanouts in paved foot-traffic areas. 3. Use Heavy-Duty, top-loading classification cleanouts in vehicle-traffic service areas.

334100 - 4

fitting, plus 6-inch (150-mm) overlap, with not less than 6 inches (150 mm) of concrete

with 28-day compressive strength of 3000 psi (20.7 MPa).

opening large enough to allow 3 inches (76 mm) of concrete to be packed around

entering connection. Cut end of connection pipe passing through pipe or structure wall to

conform to shape of and be flush with inside wall unless otherwise indicated. On outside

of pipe, manhole, or structure wall, encase entering connection in 6 inches (150 mm) of

concrete for minimum length of 12 inches (300 mm) to provide additional support of

collar from connection to undisturbed ground.

3.9 FIELD QUALITY CONTROL

A. Inspect interior of piping to determine whether line displacement or other damage has occurred. Inspect after approximately 24 inches (610 mm) of backfill is in place, and again at completion

of Project.

1. Submit separate reports for each system inspection. 2. Defects requiring correction include the following:

a. Alignment: Less than full diameter of inside of pipe is visible between structures.

b. Deflection: Flexible piping with deflection that prevents passage of ball or cylinder of size not less than 92.5 percent of piping diameter.

c. Damage: Crushed, broken, cracked, or otherwise damaged piping. d. Infiltration: Water leakage into piping. e. Exfiltration: Water leakage from or around piping.

3. Replace defective piping using new materials, and repeat inspections until defects are within allowances specified.

4. Reinspect and repeat procedure until results are satisfactory.

B. Test new piping systems, and parts of existing systems that have been altered, extended, or repaired, for leaks and defects.

1. Do not enclose, cover, or put into service before inspection and approval. 2. Test completed piping systems according to requirements of authorities having

jurisdiction.

3. Schedule tests and inspections by authorities having jurisdiction with at least 24 hours' advance notice.

4. Submit separate report for each test.

C. Leaks and loss in test pressure constitute defects that must be repaired.
