Dave, '10 Handbook, 10.10.2.2, "The trench must be backfilled prior to hydrostatic testing to prevent movement of underground piping. The backfilling can take place between joints if it is desired to observe the joints for leakage and if the backfill depth is sufficient to prevent movement..."

It failed the hydrotest. I went to look up in 13 and 24 the "requirement" that underground piping be tested before being buried. I can't find it. Is my memory bad (no comments about old age, Ron, please) or am I perhaps thinking of a best practice that I previously included in a spec? Any help in finding that would be appreciated.
