Fittings must be non-flare compression type with stainless steel pipe stiffeners, heat-fused, or electro-fused. An isolation ball valve (brass, ¼-turn handle) and polyethylene valve box (minimum 21 inches length × 16 inches width × 12 inches height; recommended manufacturer: NDS or approved equal) are required.

The contractor must maintain 30-inch horizontal and 12-inch vertical separation between water and sewer lines, provide thrust blocking at direction changes, and install the pipe at minimum 30 inches depth. Trenches must be hand-tamped initially with 6-inch lifts until 12 inches covers the pipe, then final backfilled with 12-inch mechanical lifts to match surrounding soil density. All work must be inspected and approved before covering, with leak testing required before backfilling. The contractor must provide a minimum one-year warranty on all materials and labor and restore the site to original condition upon completion.
