Primer shall first be applied to the outside of the Pipe and the inside of the fitting socket with a small paint brush. After priming, solvent cement shall be applied to the outside of the pipe and inside of the fitting socket with a small paint brush. Solvent shall be applied in such a manner that no material is deposited on the interior surface of Lila pine or extruded into the interior of the pipe during joining. The coated surfaces shall be immediately pushed snugly together and the pipe rotated approximately 1/4 turn to insure uniform distribution of cement. Excess cement on the exterior of the joint shall be wiped clean immediately after assembly. Care shall be exercised in assemblying a pipeline with solvent welded joints so that stress on previously made joints is avoided. Handling of the pipe following jointing, such as lowering the assembled pipeline into the trench, shall not occur prior to the set times specified in ASTM D2855. The pipeline shall not be exposed to water for 24 hours after the last solvent welded joint is made. *306-1.2.13 Utility Crossings, Separation and Protection All utility crossings, separation and protection requirements shall conform to the City's Standard Drawings for separation between reclaimed water mains and conflicting utilities. *306-1.2.14 Installation of PVC Pipe PVC pipe installation shall be in accordance with ASTM D2774 and these Standard Specifications.
