PW Eagle produces PVC pipe for a variety of applications servicing the potable water, well casing, sewer, turf, agriculture, plumbing, communications and electrical markets. Our eleven manufacturing facilities in Oregon, Washington, California, Utah, Nebraska, Texas, Missouri and West Virginia assure on-time delivery. PW Eagle C905 high pressure water pipe combines superior materials with the latest manufacturing technology. PW Eagle products meet or exceed industry standards because of our rigorous quality-control program. PW Eagle supports the PVC pipe industry’s efforts to maintain the highest design and manufacturing standards. We are members of the Uni-Bell PVC Pipe Association and American Water Works Association (AWWA). Why more specifiers choose PW Eagle C900 for potable water systems. 2 Corrosion Resistance C900 is immune to nearly all types of internal and external corrosion. Since PVC is a non-conductor, it is not affected by electrolysis. Nor is it sus- ceptible to alkaline or acid soil condi- tions. A correctly installed PW Eagle system will provide long-term service at reduced operating costs. Water Quality Extractant water purity tests performed by independent test laboratories ensure that our pipe meets the requirements for water purity as specified by ANSI/NSF Standard 61. Superior Flow Characteristics An extremely smooth inner surface gives C900 a Hazen-Williams flow coefficient of C=150. This means less burden on pumps and reduced pumping costs, because there’s less friction between moving water and pipe walls. Exceptional Strength and Durability Every piece of C900 is hydrostatically proof tested at four times its pressure class. A 2.5-to-1 safety factor is applied to the long-term pressure capacity of the pipe. The resulting value is further reduced by a surge pressure value, which also incorporates a 2.5-to-1 safety factor. Burst test pressure capability of C900 Class 150 is at least 755 psi, with sustained pressure test capability of 500 psi. Throughout the country, in all conditions and climates, C900 has served admirably in municipal water mains, fire lines, and sewage force mains. Joint Integrity PW Eagle’s integral bell gasketed joint meets the same strength requirements of the C900 pipe, as well as the demanding test criteria of ASTM D 3139. The ability of PVC to bend without breaking allows the joint and pipe assembly to compensate for minor earth movement, which can cause problems in more rigid, non-PVC assemblies. Certification C900 is periodically tested to maintain listings from Factory Mutual System* (FM) and Underwriters Laboratories (UL). C900 also conforms to applicable requirements of the Uniform Plumbing Code™. *Factory Mutual is not applicable to Class 100, DR 25 products. 3 Basic Assembly Instructions 1. Clean all debris from the bell end of the pipe. Check the gasket position. Be sure it’s completely seated in the groove, with no raised areas. 2. Lubricate the spigot end, using only the PW Eagle recom- mended lubricant supplied with the pipe. 3. Place the pipes in straight alignment. Assemble to the insertion line on the spigot—but no farther. See the PW Eagle installation guide for more detailed instructions. 1. 2. 3. Hydraulics C900’s pipe wall is extremely smooth and energy-efficient. It has a Hazen-Williams coefficient of C=150. Pressure Class PW Eagle offers a choice of three pressure classes (100, 150, and 200) which can be used where operating pressures do not exceed the pressure class plus surge allowances. When you have questions or encounter unusual circumstances, call a PW Eagle representative.

The integral bell is tested with the pipe. Falling Weight Impact Test C900 withstands an impact energy of 100 ft-lbs, per the requirements of UL 1285. Quick Burst Test Randomly selected C900 samples are tested in accordance with ASTM D 1599 to withstand pressures listed below. Class 100 has a minimum burst pressure of 535 psi; Class 150, a minimum burst pressure of 755 psi; Class 200, a minimum burst pressure of 985 psi. Pipe Stiffness C900 meets these minimum stiffness requirements: Quality Assurance Longitudinal Bending Axial deflection at the pipe joints is not recommended, However, it is possible to curve C900 to allow for slight changes in direction. Bending to these minimum radii will not jeopardize C900’s design capability. See PW Eagle’s Technical Bulletin “Longitudinal Bending of PVC Pipe” for more details. Nominal Minimum Pipe Size Bending Radius (inches) (feet) 4 100 6 145 8 190 10 235 12 275 Note: Values are estimated for horizontal thrusts at depths of burial which exceed 2 feet. Note: These values should be used only for estimating purposes. Values for design should be determined by an engineer familiar with site soil conditions. Table 2.

Use embedment material that is free of large stones, frozen matter, or other debris. Use proper compaction procedures to provide soil densities as specified by the design engineer. Service Connections Direct Tapping:Direct taps may be made in C900 Class 150 and Class 200 in nominal sizes 6 inch through 12 inch. Corporation stops should be in sizes 5⁄8, 3⁄4, or 1 inch. When sizes larger than 1 inch are required, tapping saddles or sleeves should be used. Saddle Tapping:Saddle taps may be made in any size or class of C900 pipe. Maximum outlet size recommended for saddle taps is 2 inches. For sizes larger than 2 inches, a tapping sleeve should be used. Tapping Sleeves:Tapping sleeves may be used on all sizes and classes of C900. Sleeves are available up to size-on-size. Caution: Saddles and sleeves should not: • Distort the pipe when tightened • Have lugs that dig into the pipe when the bolts are tightened • Have a clamping arrangement not fully contoured to the outside diameter of the pipe For more information on tapping, see Uni-Bell’s tapping video and publications Uni-B-8 and Uni-Pub-8.

The “push on” features of our joints provide many installation advantages, but without adequate thrust restraint they can become “push off” problems. The large thrust forces present in water-distribution systems (see Table 1) require thrust restraints designed to handle test and peak operating pressures. Concrete Thrust Blocks If concrete thrust blocks are used, the size and type of thrust blocking must be based on the load-bearing capacity of the soil, pressure in the pipe, and diameter of the pipe. Table 2 provides conservative estimates of load-bearing values for various soil types. When soil conditions are not known, samples should be tested to determine soil properties. Mechanical Restraints If mechanical thrust restraint devices are used, they should be a type designed for use with PVC pipe. The devices should meet the test requirements of Uni-Bell’s Specification Uni-B-13 “Joint Restraint Devices for Use with PVC Pipe.” Design manuals and computer software are available from the restraint manufacturers. For typical thrust blocking and mechanical thrust restraint examples, see Figures 1 through 6. 7 Thrust Restraint FIGURE 1: Through line connection, tee FIGURE 2: Direction change, elbow FIGURE 3: Change line size, reducer FIGURE 4: Through line connection, cross used as tee FIGURE 5: Direction change, elbow FIGURE 6: Direction change, tee used as elbow THRUST BLOCKS MECHANICAL THRUST RESTRAINT DEVICES Place sufficient backfill before pipe filling and field testing. Under conditions requiring immediate back- filling of trenches, test after backfilling but prior to placement of permanent surface. Testing short lengths of pipe first will verify proper installation and joint assembly. If concrete thrust blocks are required, allow sufficient curing before testing. Separate tests for pressure and leakage may be performed. If separate tests are done, the pressure test should be done first. See Table 4. Procedure While the line is under pressure, check for leaks in all exposed pipe, fittings, valves, and hydrants. Repair or replace all defective elements. Repeat the test until all visible leaks stop and the allowable leakage requirements are met, per Table 5. For detailed pressure-testing requirements, consult your engineer or the PW Eagle installation guide. Table 5.

Injury or death may result due to the cata- strophic nature of pipe failure should failure occur. Rapid expansion of compressed air could propel shards of plastic throughout the area. WARNING:Expel all air from the pipeline during filling and again be- fore testing for pressure or leaks. Automatic air-release valves are rec- ommended. Compressed entrapped air can greatly amplify surges or pumping pressures. Also, com- pressed air might leak through a joint that will not leak water.
