Although, Standazd Plan Ptos. 505 and 506 will work quite adequately in many situations, Lty should not be used to su6stitute for professional engineering design, particulazly in situations invp(ving lazge diameter pipe lines (greaier than 12 inches), high velocity simations (greater than 10 ft/sec), or soils where soil rype or srabilit� may be quesrionable. One of the more r mmon cases of thn�st block failure is the installation of thrut�t blocks in unstable soil, or in ]ocations too close to ueuches for� other pipe lines. 5-14 HYDROSTATIC PRESSU1tE TFST .0'� water mains and appwtenances shall be hydrostatically tested az speeified in Secdon 7-11.3(11) of the A'�DOT/APNA Srandard Specifications.
