What is the proper procedure for pressure testing of JM Eagle’s pressure pipe?

The recommended maximum test pressure of installed PVC pressure pipe is 1.50 times the anticipated working pressure of the system; however, if the test pressure exceeds the rated pressure, the maximum test pressure should be the rated pressure. In addition, in no case should the test pressure exceed the rating of the valves or fittings, whichever is less. The typical test duration is 2 hours. Ensure that all the air is removed from the pipe prior to testing.

JM Eagle™ does allow testing of the system to 50 psi above the rated pressure for C900 pipe only. For DR 14 C900 pipe, this would be 250 psi. Make sure that the valves, fittings, and thrust blocks will be able to handle the extra pressure. The AWWA C900 standard is conservative compared to all other PVC pipe standards regarding the allowable pressure of the pipe, but that does change the fact that a DR 14 pipe made to this standard is marked with an allowable rated pressure of 200 psi.
